  What effect would talking about doping have? All players in a classical doping game have the option of telling their opponent that they will announce their doping decision before the sports competition is executed. What effects, if any, would such a move have? This question is analysed in the paper at hand. As opposed to most people’s intuition, the effect on classical doping games is limited. Still, some peculiar situations prove otherwise.

  This paper examines the role of compensatory and subjective scoring elements in determining competition outcomes in ski jumping. Using detailed data from seven seasons of men’s World Cup events (2010/11–2016/17), we decompose final scores into their constituent components: jump distance, style points awarded by judges, wind compensation, and gate compensation. We then simulate alternative ranking systems that exclude one or more components to assess how much they matter for event- and season-level standings. Our results show that jump distance alone explains most of the variation in rankings, and that removing style, wind, or gate points individually leads to only modest statistical changes in aggregate correlations. However, even small positional shifts — often one or two places — can be decisive for professional athletes, affecting prize money, sponsorships, and career trajectories. The findings illustrate a central tension in the design of scoring systems: subjective and compensatory elements may appear marginal in statistical terms but can have substantial consequences for individuals and for perceptions of fairness. By situating ski jumping in the broader economics literature on contests, subjective evaluation, and institutional design, we highlight how this case sheds light on the trade-offs between transparency, fairness adjustments, and competitive incentives in performance evaluation systems.

• Haugen, Kjetil K. (2024). The paradox of wealth : a satirical exploration of intelligence and financial success. Qeios. doi: 10.32388/VLZQ4U. Full text in Research Archive Show summary

  This brief commentary presents a satirical examination of the relationship between wealth and intelligence, challenging the conventional wisdom that links financial success with rational decision-making. Through humorous and provocative arguments, the manuscript posits that achieving extreme wealth often involves taking significant risks, which may be seen as irrational or “stupid” by conventional standards. Using a combination of economic theory and anecdotal evidence, the discussion explores how high-risk decisions can lead to substantial financial gains, while also highlighting the absurdity of measuring personal qualities by wealth. This analysis aims to provoke thoughtful reflection on societal values and the true determinants of financial success. By engaging with themes such as risk-taking, economic theory, and societal perceptions of wealth, this concise contribution invites a broader discussion on the nature of financial success and the qualities it truly reflects.

  This article investigates training in sports and argues (and demonstrates) that training (game-theoretically) works exactly as doping do. That is, the Nash equilibrium is, under reasonable assumptions, a Prisoner’s Dilemma outcome. Furthermore, several other performance improving categories within sport are examined, and proven to behave similarly. Finally, a link to general competitive economic activity is examined and proven NOT (necessarily) to have similar characteristics. The article also discusses (initially) the Prisoner’s Dilemma game and its lack of a sensible definition. Such a definition is proposed, although this proposition is not considered the main finding in the paper. Keywords: game theory, prisoner’s dilemma, economics of doping

  This article argues by casual empirics that a low draw percent in chess may work as a simplified cheating indicator. Data from a large number of historical chess games (53331) indicate that this extremely simple heuristic may be used as a first test if suspicion of cheating arises for professional chess players. This heuristic does not prove any cheating, but it may be applied as a quick primal indicator of potential cheating behaviour for a player suspected of cheating.

  This paper demonstrates, by simple classical game theory, that the claim by Savulescu et al. (2004) of a safer and fairer sport with legalized doping is a highly unlikely outcome. This result, with added arguments related to adverse effects on both demand and supply for the sports product, should hopefully affect the debate on legalization of performance-enhancing drugs. The Nash equilibrium obtained in the analysis predicts more doping, and maybe more importantly, use of more dangerous performance-enhancing drugs. As a consequence, a legalization of performance.enhancing drugs may threaten the actual existence of professional sports markets

  Based on an assumption of an existing scoring probability difference between two teams engaged in a football match, the conditional probability distribution given the number of goals in the match for the low quality team beating the high quality team, is derived. Furthermore, similar distributions for the high quality team beating the low quality team as well as a draw are also derived. Based on a Poisson distribution of goals, we discuss a potential for optimizing expected uncertainty of outcome (UO) by adjusting intra-match rules or league rules for team sports. The main variables in this regard are (i) the typical number of goals scored, and (ii) the evenness of competing teams. We identify a curve defining the optimal expected number of goals as a function of team quality difference.

  The 50th anniversary of the McClintock effect deserves a new view on the subject. This paper applies (evolutionary) game theory to gain further insight. Among interesting results are strong indications of Nash equilibria in mixed strategies, indicating that the effect depends on parameters characterizing both females and males in the group. As such, much of the empirical research conducted on the subject over the last 50 years may be questioned. Furthermore, the article predicts that the effect’s potential presence depends strongly on female envy/jealousy as well as male preferences on female attractiveness

  This article applies game theory to explain why football clubs have a tendency to sack their managers when relegation is a realistic option. As opposed to coach succession literature, which typically reports contradiction between theory and practice, this article produces credible explanations for this “problem”. In addition, observations indicating accelerated manager replacements in modern professional football are also easily explained. Derived Nash equilibria are also quite robust to parameter assumptions and hence the possible variations.

  After many years of teaching utility maximization in Microeconomics a certain paradoxical puzzle has come to our attention. It is very simple and straightforward, but we still find it hard to explain it to students. Our hope is that the distinguished community of theoretical economists may help us solve this mystery. After all, we would find it extremely unlikely that we are the first persons to identify this paradox. Keywords: microeconomics, utility maximization, demand curve, market demand curve, supply curve

  Optimal values of parameters which play the major role in the implementation and financial sustainability of waste-to-energy plants technology can be obtained through the solution of mathematical programs corresponding to the minimization of total costs for the waste treatment. However, decisions based on the idea of total costs minimization can neglect the behavioural aspect of the problems and assume full cooperation between waste producers, which might not occur. The aim of this paper is to present possible approaches to modelling of cooperation between the waste producers in a certain location in the setting with limited or banned landfilling using the apparatus of cooperative game theory. The underlying idea is to justify and formalize the decision-making process leading to a cooperative reduction of the costs for non-recyclable solid waste treatment. In this paper, each application-oriented class of cooperative games is briefly described, and the games modelling interactions between waste producers in exemplary problems with different cooperation restrictions are defined. The Shapley value and its modifications are calculated for these games in order to present possible development of waste producers’ costs in a case of cooperation and to demonstrate the distinction between considered classes. The main contribution is an introduction of the newly implemented cooperative game theory approaches enabling analysis and prediction of waste producers’ behaviour. These approaches are suitable and prospective for the further research in the field of waste management and can be used in a prediction of the impact of WtE plants building on public finances and assessment of the waste treatment infrastructure sustainability.

  This article discusses an alternative to Video Assisted Refereeing (VAR) in football. An alternative option of positively adjusting the distance from the penalty spot to the goal, leading to a decrease in penalty scoring probabilities is suggested. 90 years of empirics from Serie A in Italy is used to discuss the suggested method. The article concludes by an example illustrating the proposed method. Keywords: serie A, penalty kicks, VAR, football, 12-yard mark

  This article presents an algorithm, which by taking both goals scored as well as matches played into account, is meant to provide \more sensible" top scorer lists in football. The algorithm computes Upper Hulls recursively in order to provide a new and improved list. The complexity of the algorithm is reasonable, and should imply practically feasible execution on a modern computer. The proposed algorithm may also be an interesting alternative to academic scholar ranking. It has interesting properties for instance compared to the h-index.

  The article formulates, solves and draws inference from a game model intended to shed light on the evolution of artificial turf in professional European football (soccer). The main results indicate that quality of teams (sports performance-wise) define which teams choose to play on artificial turf or not. Furthermore, teams with low quality are predicted to be the "artificial turf pioneers", both model-wise, as well as indicated by some empirical examples. The fact that artificial turf may play a significant role also in the evolution of uncertainty of outcome is interesting and is commented on in the conclusion.

  This article proposes an alternative mathematical formulation to one (among many) ways of estimating Uncertainty of Outcome. This alternative formulation holds potential to make such estimation processes easier for both practitioners as well as researchers. Additionally, some approximative estimators are derived, tested and discussed. Even though these estimators may not perform perfectly for football leagues, they may have stronger potential for use in other sports.

  In this short note, we offer a suggestion that we believe may be ethically sound for research. Requiring co-authors to be able to deliver a reasonable presentation of a paper may lead to co-authors being fewer in number and more representative in nature. A research market involving research papers with hundreds of au- thors, single authors who have been credited with several hundred articles, or strict definitions of who has done what can be troublesome for public faith in research. To some extent, the public view of research as very trustworthy has changed and academic society should consider radical propositions to regain its position as solid and credible.

  In this article, a new set of rules in professional handball, introduced in July 2016 are discussed. The discussion is aided by a reasonably broad empirical analysis, comparing uncertainty of outcome between European handball and football (soccer). This analysis indicates that European handball, already before the introduction of the new rules, may have had problems with severe lack of uncertainty of outcome. Given this fact, we discuss the new rules, and conclude that they may lead to further increased competitive imbalance (reduced uncertainty of outcome) in handball. Such a conclusion should be of interest for handball officials, especially when the new set of rules, here identified as possibly harmful for uncertainty of outcome, still are under debate.

  The purpose of this study is to analyze the consequences that point score systems in association football may have on potential collusion between teams. The study applies game theory and empirical analysis to derive and test hypotheses. The main findings of the article include Nash equilibria indicating a higher collusion potential associated with the 3-1-0 point score system than with the 2-1-0 system. Of particular interest is the finding that the competitive balance of the league affects collusion, and that (theoretically) high competitive balance in fact makes collusion more probable. Empirically, we are not able to prove that real-world participants do collude, but we provide circumstantial evidence that is consistent with collusion. The empirical analysis is based on a sample of 25 European top leagues with 823 played matches in the 2017 and 2016/17 seasons. These data are used to estimate uncertainty of outcome and draw ratio. We apply a standard t-test to test our main hypothesis. The main conclusion of the paper may hence be summed up as advice to reinstall the 2-1-0 point score system in association football.

  This article applies economics of doping theory (game theory) to corruption. Similarities, and significant differences between the two topics are identified. As a consequence of such differences, the corruptive action - the bribe - is introduced as a decision variable for the players. Nash equilibria of the "corruption game" are structurally similar to the doping-situation - e.g. "everybody is corrupt". However, the size of the bribe becomes, as a consequence of a significant revision of the basic models, "as high as possible"; indicating that the event corruption case should be at least as hard to handle as the doping problem and with possibly even more drastic adverse effects. Although the article focuses on corruption in sports and events, the results are also relevant for other types of corruptive action. Corruption in sports is a problem threatening the existence of professional sports. Methods for better understanding, which we present in this article, are hence of vital importance for the professional sports business. Keywords: game theory, economics of doping, economics of corruption, bribe equilibrium.

  This commentary discusses how the rules of the game may affect doping positively and negatively. The link between rules and doping prevalence is established. Some examples are given, indicating what to do and not. The main scientific outcome of the paper is perhaps that the fight against doping can be performed cheaper than through classical means such as improved test quality/higher test frequency, or less progressive (more egalitarian) prize functions, or tougher sanctions. As such, the recommended strategy may be seen as a “Columbi Egg”. But, as always, nothing comes for free, and some serious creativity in sport redesign is needed to realize this method’s potential.

Still, a simple comparison between win and profit maximising game models indicate surprising complexity in game prediction.

  The Norwegian company EWOS AS produces fish feed for the salmon farming industry, supplying approximately 300 customers spread along the coast of Norway. The feed is produced at three factory locations and distributed by a fleet of 10 dedicated vessels. The high seasonality of the demand and the large number of customers make the distribution planning a substantial challenge. EWOS handles it by operating a system of mostly fixed routes with decentralized planning at each factory. The distribution can be described as a multi-depot vehicle routing problem with time windows, multiple vehicle usage, inter-depot routes, heterogeneous fleet and a rolling horizon. The paper presents a mathematical model for this problem, which is solved by heuristics and meta heuristics. Based on detailed historical data collected by EWOS during the autumn of 2010, the model has proposed a dynamic set of routes with a significant reduction of travelled distance - close to 30% - and an increase of average vessel fill-rate - from 60% up to 95%. This implies a substantial fuel saving, with a positive environmental impact, and also a potential for downscaling the fleet, with additional considerable cost savings for the company.

  In this paper, a game between two football (soccer) teams is analysed. The focus is on how the choice of point score system may affect Nash equilibria in a given simultaneous game and a corresponding sequential version. The reason for this choice, is (to some extent) experience related to the growing secrecy on pre-game strategic choices among football coaches. It is demonstrated by the relatively simple game theory, that the point score system plays a vital role in how teams (coaches) will “play” such games, given that they are rational and recognize Nash equilibrium as a reasonable game prediction. In fact, some evidence on an increased tendency for more pre-game strategic secrecy is logically established in a move from a 2-1-0 point score system to a 3-1-0 point score system.

  This paper applies simple game theory to investigate an equilibrium link between composition of football clubs’ fans preferences and the clubs’ talent acquisition decisions. Such a link is identified, and wealth of the clubs turns out to be important for such equilibria to be established. However, even poor clubs can reach equilibria where they end up being winners of the “talent-acquisition-game”, given that their fans are ‘die-hard’ enough. In short; clubs with a long history and a dedicated fan base are much better prepared for successful competition in the football market.

  The effect of advertising on sales has been the subject of recent studies as an important aspect in many demand-based problems. Herein, we deal with the newsvendor problem, due to its simple structure, as a suitable tool for illustrating how facets of marketing may affect decision-making concerning operational problems. In the setting presented, the newsvendor is faced with advertising-sensitive stochastic demand, where a demand-related random element comprises an advertising decision of the multiplicative or additive form. We assume that a suitable advertising strategy results in increased sales. Two advertising response functions are considered, these being concave downward and S-shaped. We review and extend the existing results relating to the newsvendor problem with marketing effects, which mostly pertain to the concave function. These are generalized by defining the S-shaped function, and some original insights into the effect of advertising are given. We establish that the optimal advertising expenditure for the multiplicative case is always less than or equal to the optimal amount in the equivalent deterministic model while it is always equal in the additive case. We finally illustrate the results that are obtained by providing numerical examples involving various advertising response functions, as well as management-related interpretations.

  The new Norwegian system for calculation of publication credits is examined. The new system was launched due to criticism for penalizing collaborative research. It turns out that adverse incentive problems emerge as a result of this system change. We show by a simple case, that institutions will benefit (credit-wise) by adding more authors to a scientific publication. Even worse, the beneficial effect increases the more authors the paper has initially. Alternative cases indicate even stronger incentives for co-author maximization.

  In this paper, a game between two bookmakers is analysed. The simple game involves high or low odds strategies for each bookmaker, and an inherent Prisoner's Dilemma structure is revealed. However, this structure may be partially resolved given parametric changes in profit structures that might lead to a "Stag Hunt Game". An argument for possible bookmaker arbitrage is added. Although this argument is well known, it is sparsely treated in research literature. A proof of the necessity of differing beliefs between gamblers to obtain bookmaker arbitrage is added.

  In this article, we present further discussion provoking explanation, why the existing fight against doping in sport is not fully successful although widely presented in media. Our paper is based on economical arguments derived from discussions of practitioners due to lack of statistically valid data and their fundamental mathematical modeling. Hence, the maximization of a (two-variable) sports attendance demand function, depending on athletes’ performance and doping prevalence, may result in a positive optimal doping prevalence and explain the existing sport doping related situation. Given reasonable assumptions on relevant functional behavior, this result can be interpreted as an incentive for sports officials to allow (and even welcome) some doping. As a consequence, we conclude that one should not be surprised that doping exists and is widespread under the assumption of aggregated rational behavior that is common in economical research. Therefore, the need for a global coordinated system of testing and sanctions decoupled from sport may be a necessary condition in order to meet these challenges and together with the proposed model should be the subject of further discussions.

The system is operated by Omya’s regional office in Cologne, Germany, responsible for distribution planning at the regional distribution center (RDC) in Moerdijk, the Netherlands. The distribution planning is a vital part of supply chain management of Omya’s production of Norwegian high quality calcium carbonate slurry, supplied to European paper manufacturers. The DSS operates within a vendor managed inventory (VMI) setting, where the customer inventories are monitored by Omya, who decides upon the refilling days and quantities delivered by barges. The barge planning problem falls into the category of inventory routing problems (IRP) and is further characterized with multiple products, heterogeneous fleet with availability restrictions (the fleet is owned by third party), vehicle compartments, dependency of barge capacity on water-level, multiple customer visits, bounded customer inventories and rolling planning horizon. There are additional modelling details which had to be considered to make it possible to employ the model in practice at a sufficient level of detail. To the best of our knowledge, we have not been able to find similar models covering all these aspects in barge planning. This article presents the developed mixed-integer programming model and discusses practical experience with its solution. Briefly, it also puts the model into the context of the entire business case of value chain optimization in Omya.

  In this paper, we follow up research of Vatne [23] related to how mentally ill patients could (and perhaps should) be treated. We propose, model, and analyze a simple sequential game of incomplete and asymmetric information where the patient moves first, signaling behavior which is observed by the therapist with lack or limited knowledge of the actual patient type. We assume greatly approximated strategy spaces both for patient and therapist, but will still claim that our results increase knowledge of this important relation. Knowledge that may be critically important in continued improved treatment of patients with mental illness.

  The aim of the paper is to introduce a modified hybrid algorithm to solve a wait-and-see reformulation of transportation optimization model with random demand parameters and 0-1 network design variables. Firstly, the deterministic linear transportation model with network design variables is reviewed. Then, uncertain demand parameters are intorduced and modeled by random variables. The following deterministic reformulation is based on the wait-and-see (WS) approach. Finite discrete probability distributions are assumed for all random variables, and hence, the obtained separable scenario-based model can be repeatedly solved as a finite set of mixed integer linear programs (MILPs) by means of integer programming techniques or some heuristics. However, the authors combine a traditional optimization algorithm and a suitable genetic algorithm to obtain a hybrid algorithm that is modified for the WS case. Its implementation and test results illustrated by figures are also discussed in the paper

  This paper applies simple game theory in order to analyze the UEFA Financial Fair Play (FFP) policy, which was fully implemented in the 2013/14 season. By involving budget constraints put on clubs, FFP may lead to unintended or even adverse effects as indicated by some of the obtained results. In particular, the analysis shows that due to being in the situation of a Prisoner’s Dilemma, the clubs have a strong incentive to bypass the new regulations, what results in additional costs both for clubs to hide and UEFA to detect deviant behavior. As these costs might deter small clubs from trying to cheat, this consequently must have negative consequences on the level of competitive balance within a league. However, a positive outcome of FFP might be that clubs become more independent from benefactors or sugar daddies.

  In this research note, we discuss a peculiar development in the Norwegian top football league - ‘Tippeliagen’. Since 2007, a significant drop in attendance numbers has been observed, and we investigate possible causes through regression analysis. Our main findings indicate that we can explain the complete attendance figures from 1993 to 2013 by a surprisingly simple regression model, including only (binary) new stadium variables. In addition, we estimate the duration of stadium attendance effects that turns out to be 5 years in Norway. In latter parts of the note, we discuss the sense in this model and conclude that a ’gametheoretic’ signaling model may prove worthwhile as an underlying explanatory model.

  This paper presents a model which aims to find an optimal treatment time for patients with musculoskeletal diseases. The stochastic dynamic programming model presented is based on minimizing expected costs given a stochastic processes for cure with and without treatment as well as costs for treatment and reduced quality of life as a consequence of the disease. The main results derived in the paper include explicit conditions for an interior optimal solution and a simple and intuitive approximate solution. Even though the presented model is specifically aimed at musculoskeletal diseases, the model's generality should make it applicable for a wide range of disease treatment strategies.

  The purpose of the paper is to present a hybrid algorithm to solve a transportation optimization model with random demand parameters and network design variables. At first, the classical deterministic linear transportation model with network design 0-1 variables is introduced. Then, randomness is considered for demand parameters and modeled by here-and-now approach. The obtained scenario-based model leads to a mixed integer linear program (MILP) that can be solved by common integer programming techniques, see e.g. the branch-and-bound algorithm implemented in the CPLEX solver. Such a program may reach solvability limitations of MIP algorithms for large scale real world data, so a suitable heuristic development is welcome. Therefore, the idea of combination of traditional optimization algorithm and genetic algorithm is discussed and developed. At the end, the results are illustrated and also verified for a small test instance by figures.

  This paper extends classical work on economics of doping into a multi-player game setting. Apart from being among the first papers formally formulating and analysing a multi-player doping situation, we find interesting results related to different types of Nash-equilibria (NE). Based mainly on analytic results, we claim at least two different NE structures linked to the choice of prize functions. Linear prize functions provide NEs characterised by either everyone or nobody taking drugs, while non-linear prize functions lead to qualitatively different NEs with significantly more complex predictive characteristics.

  This article addresses a generalization of the capacitated lot-size problem (CLSP) as well as the profit maximization capacitated lot-size problem (PCLSP) considering joint price inventory decisions. This problem maximizes profit over a discrete set of prices subject to resource limitations. We propose a heuristic based on Lagrangian relaxation to resolve the problem, especially aiming for large scale cases. Results of experimentation exhibit the major importance of the capacity constraint. When this one is weak, our heuristic performs particularly well, moreover the numbers of possible prices does not really impact the results. Keywords: Heuristics – Capacitated lot-sizing – Dynamic pricing.

  Establishing a requirement for, justifying public spending on, and evaluating the effectiveness of anti-doping policies all accentuate the need for reliable estimates of doping prevalence in sport. To date, despite considerable effort and much empirical research, this critical information is still not available. Methodological concerns that make doping epidemiology research difficult have been noted, and to some degree addressed in relation to under-reporting bias. In this paper, we use a simple game model to outline a potential responding behaviour among self-reporting athletes on the use of doping that could potentially invalidate any prevalence estimation arising from self-reports. We show a paradoxical situation in which a potential strategic behaviour inevitably leads to a game where the ‘lying’ is a dominant strategy for both doping users and non-users. A slightly more advanced look at the situation might possibly alter this seemingly absurd conclusion, however not in a direction offering any easy solutions for empirical doping research. Although we acknowledge that the proportions of respondents engaging in false telling are likely to vary across samples and differ between doping users and clean athletes, our simple model effectively draws attention to a neglected side of evasive responding in surveys. The response bias that potentially could lead to under-and over-reporting should be considered when self-reported prevalence rates are used to inform anti-doping prevention and intervention policies. Survey methodologies that are able to account for potential distortions would make a considerable contribution to doping research.

  In this paper, we demonstrate the computational consequences of making a simple assumption on production cost structures in capacitated lot-size problems. Our results indicate that our cost assumption of increased productivity over time has dramatic effects on the problem sizes which are solvable. Our experiments indicate that problems with more than 1000 products in more than 1000 time periods may be solved within reasonable time. The Lagrangian decomposition algorithm we use does of course not guarantee optimality, but our results indicate surprisingly narrow gaps for such large-scale cases - in most cases significantly outperforming CPLEX. We also demonstrate that general CLSP's can benefit greatly from applying our proposed heuristic.

  The main purpose of the paper is to present a specific case of dynamic pricing for the newsvendor problem. Firstly, the short overview of a newsvendor problem is given together with references to the selected literature and remarks to its applicability. Then, the dynamic pricing principles are discussed together with references to decision dependent randomness case in stochastic programming. The dynamic pricing problem deals with the determination of selling prices over time for a product whose demand is random and whose supply is fixed. We approach this problem by formulating the newsvendor problem, which is introduced as a single period problem in our case. We focus on the specific features of the demand function assuming decision dependent uniform distribution. We assume that its support size linearly decreases with the increase of the price. Under such assumptions, the model has suitable computational features related to the expectation of the objective function. In addition, possibility to increase the profit by the change of the price may appear. The model formulation allows us to use the MAPLE software for symbolic computations and vizualisation of results. The test results for the selected data set are visualised at the end of the paper.

  This paper studies agent-to-agent games in competition for a free public resource. The resource is not evidently scarce, scarcity may, however, be the equilibrium outcome. The agents' attributes may differ as well as quality parameters between different public resources. The examples are taken from the health sector. Based on simple two-player simultaneous games of complete information, results regarding agent equilibrium quality choices are derived. Most notably, Nash equilibria of the type: very ill patients choose low quality hospitals (denoted adverse patient allocation in the paper) are demonstrated. Furthermore, it is argued that a situation characterized by patients with relatively mild diseases but large patient variability (big differences between patients regarding the given disease) and a health system with medium competition are prime candidates for Nash equilibria characterized by such Adverse patient allocation effects.

  The purpose of the paper is to present a step-by-step development of the transportation optimization model with random parameters, network design variables and with pricing. The well-known deterministic linear transportation model with network design 0-1 variables is shortly discussed and it is extended in two separate ways. Firstly, randomness is modeled by so-called here-and-now approach and secondly the deterministic model is enriched with dynamic pricing elements. Then, the combined case is built and the original model is detailed. All cases are illustrated by computations and figures.

  This article uses simple game models to investigate penalty kick shootouts in soccer. As opposed to existing research, which mainly focuses on empirical/experimental problems, the game itself is the main focus here. Interesting findings include a proposed Nash equilibrium invariance for possible preference differences between penalty kick Executors and Keepers as well as identification and demonstration of how game models may be used in order to estimate player performance characteristics through observed Nash equilibria outcomes. A nonmixed strategy Nash equilibrium is also shown to be possible with potential interesting consequences for goal keepers.

  This essay discusses why many European football clubs have experienced financial problems, despite earning high revenues. The fact that European football clubs are win maximizers make them more aggressive when competing for talented players than professional teams on other continents. So-called eyes of a needle, such as promotion, (avoiding) relegation and qualifying for international tournaments strengthen the cost push effects. Due to the free movement of labour, any regulations have to be implemented simultaneously across the whole of Europe. Achieving such unilateral agreement in 52 national leagues is difficult. European football has a history of powerful clubs that are not favourable to regulations that can reduce their advantages. A game-theory approach illustrates the mechanisms that lead European clubs to spend more resources than they can afford. Additionally, this part offers a new and hopefully interesting explanation, besides objective function differences, when it comes to understanding micro differences between US and European sports.

  This paper proposes a simple game theoretic framework for analyzing strategic choices in soccer matches. This framework is applied in order to explain the rise and fall of soccer nations like Norway, who reach international competitive performance by introducing specialized strategies. Additionally, it is shown that the best choice for such teams may - at certain time points in their "life cycle" - not be to improve their preferred strategy further. It is actually possible to show that such a strategic choice may be disadvantageous. Finally, certain cases are shown to have characteristics such that it is "optimal", in a game theoretic perspective, to actually decrease playing strength in order to "fip" the Nash equilibrium to a more suitable one. As such, "unexpected" behavior of very good teams choosing to loose against very bad teams may be explained.

  This paper analyses soccer clubs' buying choices of foreign versus local players through simple game theory. Restricted to a single soccer match, the main result indicates Prisoner's Dilemma structures in the games. Furthermore, the game models reveal the central (logical) trade-off in the clubs' player choice: a foreign player is acquired if the player's marginal expected financial benefit exceeds his marginal cost. Also, situations that are more complex and difficult to predict are analysed, such as foreign player cost consequences, crowding costs and diverging market potential between clubs.

  This paper proposes an alternative view of classical sports economic labour market theory. Through simple direct game theory, we are able to show explanations other than the traditional marginal or average revenue equality equilibrium models of Quirk and El-Hodiri (1971). For instance, the choice of objective is important, however not vital. We build our approach directly on preliminary research by Solberg and Haugen (2010) and extend their relatively simple modelling and conclusions. Particulary, we focus on the claimed economic crisis of European football and propose more complex explanatory patterns than objective function choice for observed financial differences between US sports and European football.

  This article addresses effects caused by the transition from a 2-1-0 to a 3-1-0 award system in soccer. The first part of the article discusses consequences of the transition on offensive versus defensive play. This part may be seen as a valuable supplement to work by Brocas and Carrillo (2004) as the choice of a different game theoretic framework provides increased insight into the concept offensive/defensive play in soccer. The second and main part of the paper addresses additional effects induced by the award system transition, especially effects on competitive imbalance. It is shown by simple game theory that under a relatively general set of team descriptions, such a transition may affect competitive balance adversely. In the final sections of the paper some empirical examples strengthen the hypothesis on adverse competitive effects.

  The Norwegian company Omya Hustadmarmor supplies calcium carbonate slurry to European paper manufacturers from a single processing plant, using chemical tank ships of various sizes to transport its products. Transportation costs are lower for large ships than for small ships, but their use increases planning complexity and creates problems in production. In 2001, the company faced overwhelming operational challenges and sought operations-research-based planning support. The CEO, Sturla Steinsvik, contacted More Research Molde, which conducted a project that led to the development of a decision-support system (DSS) for maritime inventory routing. The core of the DSS is an optimization model that is solved through a metaheuristic-based algorithm. The system helps planners to make stronger, faster decisions and has increased predictability and flexibility throughout the supply chain. It has saved production and transportation costs close to US$7 million a year. We project additional direct savings of nearly US$4 million a year as the company adds even larger ships to the fleet as a result of the project. In addition, the company has avoided investments of US$35 million by increasing capacity utilization. Finally, the project has had a positive environmental effect by reducing overall oil consumption by more than 10 percent

  This paper introduces a simple heuristic for a quadratic programming sub-problem within a Lagrangean relaxation heuristic for a dynamic pricing and lot-size problem. This simple heuristic is demonstrated to work well on both "standard problem instances" from the CLSP-literature, as well as on very large-scale cases. Additionally, we introduce price constraints within the framework of dynamic pricing, discuss their relevance in a real world market modelling, and demonstrate their applicability within this algorithmic framework.

  There are two types of random phenomena modeled in stochastic programs. One type is what we may term "external" or "natural" random variables, such as temperature or the roll of a dice. But in many other cases, random variables are used to reflect the behavior of other market participants. This is the case for such as price and demand of a product. Using simple game theoretic models, we demonstrate that stochastic programming may not be appropriate in these cases, as there may be no feasible way to replace the decisions of others by a random variable, and arrive at the correct decision. Hence, this simple note is a warning against certain types of stochastic programming models. Stochastic programming is unproblematic in pure forms of monopoly and perfect competition, and also with respect to external random phenomena. But if market power is involved, such as in oligopolies, the modeling may not be appropriate.

  This article addresses the problem of competitive balance within a sports league. As opposed to standard literature on the subject, a direct game theoretic approach is made to predict trade between two marginally different teams. The main results may be summed up by proven existence of unique pure-strategy Nash equilibria that form player trade. These Nash equilibria are solely determined by the shape of the revenue function. A convex revenue function yields increased competitive imbalance, while a concave revenue function implies the opposite. The article closes by discussing some central assumptions, and the possible consequences of relaxing them.

  Antidoping work consumes huge economic resources. Formal understanding of economic forces that drive athletes to use drugs is lacking. Consequently, work on this phenomenon may be of interest to the sports community, especially the antidoping community. This study uses simple game theory to analyze simple two-player games representing various situations of sports activity. The basic findings are the existence of Nash equilibria forcing agents to use drugs that are very often the prisoner's dilemma type, and antidoping work with small or no effects may hence lead to Pareto-worsened situations. This study also shows that antidoping activity should be differentiated between sports activities. Finally, some discussions on alternative regulatory policies conclude that improved testing may not be the most efficient way to fight doping - if the fight against doping is as important as sports officials like to tell us.

  This paper uses simple game theory to analyze a situation where two agents compete in the transport market. The modeling frame is that of a mode choice model, where the two mode options are boat or car transportation. The basic findings are that non pareto optimal (car, car) equilibrium outcomes, may occur in a surprisingly large amount of cases. Additionally,the possible different Nash equilibria outcomes are fairly large leading to a situation which may be hard both to model and predict for regulatory authorities. Finally, in certain situations, subsidizing boat transportation may not lead to increased use of boat as transport modal choice. In final sections of the paper, the case of demand uncertainty is examined. The basic findings here, is that unique Nash equilibria where both agents choose car emerge as a consequence of added uncertainty.

  This paper shows that market values for UK football (soccer) teams may be described by a remarkably simple regression model. This model is used to estimate the value of the Premier league. A tentative estimate of the Norwegian club Rosenborg Ballklubb is also established. As Rosenborg Ballklub is a 'membership club' – meaning that a small entrance fee (independent of the clubs performance) is the real price of 'a share' in the club – the return of an investment in the club is shown to be 'unbelievable'.

  In a great many situations, the data for optimization problems cannot be known with certainty and furthermore the decision process will take place in multiple time stages as the uncertainties are resolved. This gives rise to a need for stochastic programming (SP) methods that create solutions that are hedged against future uncertainty. The progressive hedging algorithm (PHA) of Rockafellar and Wets is a general method for SP. We cast the PHA in a meta-heuristic framework with the sub-problems generated for each scenario solved heuristically. Rather than using an approximate search algorithm for the exact problem as is typically the case in the meta-heuristic literature, we use an algorithm for sub-problems that is exact in its usual context but serves as a heuristic for our meta-heuristic. Computational results reported for stochastic lot-sizing problems demonstrate that the method is effective.

  In the continental shelf off the coast of Norway, there are several petroleum fields containing a mixture of oil and gas. A multiperiod mixed integer programming model for investment planning for these fields has been used by The Norwegian Petroleum Directorate for more than fifteen years. In practical use, the production from each field has mostly been declared to follow profiles given by the user, but the user may also declare that the production can vary from the given profile. This paper describes the model and comments on some of the real problems the model has been used to analyze and the modeling process involved.

  This paper describes a serial and parallel implementation of a hybrid stochastic dynamic programming and progressive hedging algorithm. Numerical experiments show good speedups in the parallel implementation. In spite of this, our hybrid algorithm has difficulties competing with a pure stochastic dynamic programming approach on a given test case from macroeconomic control theory.

  Norwegian deliveries of natural gas to Europe have grown considerably over the last years. Additionally, plans involve even greater supplies, introducing major gas fields as the Troll field. The market for natural gas may to a large extent be viewed as a contractual market. This is normally explained by the big investments involved in development and transport. In such a perspective, the supplier's planning problem of scheduling fields and pipes may prove important in order to be able to meet contractual agreements. This paper describes a model of Stochastic Dynamic Programming type which may be viewed as a first attempt in solving this type of problem. The main focus in this model is on project scheduling and resource uncertainty. Each project's production profile is viewed as a stochastic variable. Then a possible goal could be to minimize expected deviation from a given predicted contract profile. We use the term SPSP (Stochastic Project Scheduling Problem) to refer to our problem. Besides a simplified description of the mathematical model, the paper also describes some tests with model-examples. These examples are constructed to obtain some interesting (non-intuitive) effects. The paper concludes with some remarks on complexity and speedup possibilities.

  We formulate a simple model of the interaction between a sponsor and a bureau. The sponsor sets the bureau's budget while the bureau decides on how much to spend on slack. We compute numerically Markov perfect equilibria of multi-period games where the agents move alternately and apply Markov strategies. Both agents are worse off compared to the one-period game with simultaneous moves. As the discount factors increase, the equilibrium outcome becomes less cooperative in nature.

  This Second Edition is greatly expanded from the First Edition. Four new chapters are added to summarise the authors’ collected research work on doping. Crime and NO Punishment is a rare and intellectually sharp contribution to the literature on doping, sport, and strategic behaviour. Rather than approaching doping as a moral, medical, or purely regulatory issue, Haugen and co-authors treat it as what it fundamentally is: a strategic interaction shaped by incentives, competition, and human rationality. The result is a book that is both academically rigorous and surprisingly readable. Crime and NO Punishment is one of the most insightful and original works on doping ever published. It reframes the entire debate by showing that doping is not primarily a moral failure but a structural inevitability in competitive environments. The second edition strengthens the book’s position as a foundational text in the economics of sport. For scholars, policymakers, and anyone interested in understanding why doping persists — and why it is so difficult to eradicate — this book is essential reading.

  This text gives a comprehensive coverage of how optimization problems involving decisions and uncertainty may be handled by the methodology of Stochastic Dynamic Programming (SDP). A rapidly changing world with seemingly growing uncertainty needs a modern approach to this classic methodology. The book treats discrete, as well as continuous problems, all illustrated by relevant real world examples. The book presents a comprehensive outline of SDP from its roots during World War II until today. Much of recent research are covered, as well as parts of the authors’ own original research. Algorithms and computer techniques are added when needed.

  This article discusses the obvious paradox of economic theory. What is the point of a theory that cannot work and should not work in practice? If economic theory did work, a multitude of economic models could be used to predict any variable with economic and financial consequences for humans or organizations. Knowledge of future realized values of such economic and financial variables, ranging from stock market values to the number of nurses needed in Norway in 2030, gives the power to make a profit. Given information on Apple’s stock market values in a multitude of future time periods, the information holder has the ability to buy stock when it is cheap and sell when it is expensive. Such a strategy builds risk-free profits, in principle infinitely high. We all know what happens in markets where one or a set of agents obtains infinite profits: the rest of the market will lose infinite profits, and the market breaks down. Perhaps we can say it like this: If economic theory had worked, no economy would exist.

  This article discusses "extreme" Prisoner's Dilemma games, and questions Nash equilibrium as a solution concept in such situations. A slight reformulation of the concept is suggested, securing that a more reasonable solution is chosen. A small warning to the reader: This article is special, not everything is true. That is, there are fictional parts. The reader is left for deciding what is fictional and what is science. Perhaps we could categorize the paper as a quiz where the objective is to rule out fictional parts from the content which at least is meant to be scientific.

  This brief commentary presents a satirical critique of New Public Management (NPM) practices in higher education, using a fictional university in Norway as a case study. Drawing parallels with Soviet-era production methods, we explore the implications of applying industrial management tactics to academic settings. Through a humorous lens, we discuss how such approaches can lead to a dilution of academic standards and integrity, evidenced by tactics such as lowering student assessment criteria to artificially boost pass rates and employing superficial methods to enhance institutional reputations. This analysis aims to provoke thoughtful reflection on current educational policies and their long-term impacts on academic quality, university governance, and policy formulation. We critically examine the metrics-driven approach to educational success and its consequences on teaching quality and academic freedom. By engaging with themes such as accountability in education, marketization of higher education, and the commodification of learning, this concise contribution invites a broader discussion on the sustainability of NPM strategies in nurturing genuine educational excellence.

  This (short) article/commentary discusses the video-assisted referee (VAR) system in association football. Based on simple logic, the link between uncertainty of outcome and VAR is established, and the article concludes that general introduction of the VAR system may be harmful to association football as it may lower uncertainty of outcome to levels which may seriously harm future demand. Keywords: video-assisted referee, uncertainty of outcome, adverse effects

  Pricing and advertising principles have been recently applied in decision making problems of several application areas. Among them, we deal with transportation networks and related network design problems that serve to logistics of energy resources within considered regions of the Czech Republic. Transportation of certain types of raw materials often requires modifications of the used network structure. Especially, when random demands and amounts of resources need to be taken into the account, the robust network is necessary. To study possible flexibility of the obtained network structures, we assume that stochastic demand can be both pricing and advertising sensitive. Using suitable nonlinear dependencies (pricing-demand and advertising-demand related) we model the problem by a scenario-based two-stage mixed integer nonlinear stochastic program. Test computations are realized for simulated and real application based data. Software implementation in GAMS, and its modifications based on hybrid algorithms, are also discussed.

  In this short note, I address the question many of us have had a “YES-feeling” about all our lives. Does getting stinking rich implicate wisdom, or might it be the other way around? Or, may wisdom have no causality to the concept at all? Hopefully, through relatively easy arguments, I will try to persuade the reader to believe – as I do – that one must be really stupid to get really rich.

  For people with a genuine interest in sports - what's going on in the women's soccer league?; how did Roger Federer do in Rogers Cup?; who's ahead in the Formula 1 circus? It's probably rather difficult to fully grasp the economic and financial foundations of modern competitive sports. What does it mean for example that a European club football team buys players for sums exceeding 120 percent of the club's turnover? How does one go about staging a sporting event that lasts two to three weeks with a turnover of more than £2 billion, which, by the way, exceeds the GDP of some African countries? What is behind the French car brand Citroën's sponsoring of the Chinese national badminton team? You won't find the answers to these questions in Stefan Szymanski's latest book Play Books and Cheque Books: An Introduction to the Economics of Modern Sports (Princeton University Press), but the fundamental issues of sports and economics are elucidated for, says our reviewer Kjetil K. Haugen, even novices to the terminology of the economics sciences. The author has totally refrained from using the language, formulas and diagrams of mathematics. This is brave, but, according to Haugen, there are unwanted consequences in terms of communicative inefficiency, in an otherwise good book.

  The upstream natural gas infrastructure development is crucial for the Norwegian natural gas sector. This paper introduces a two player game which describes the competition between two natural gas companies while they are developing new upstream natural gas pipelines. Different Nash Equilibria are demonstrated under different circumstances. Given our assumptions, we observe that tariffs can influence development of new pipelines. Natural gas companies will minimize their new pipelines' size if they can rely on others' infrastructure, and the current Norwegian natural gas transportation system may give rise to such situations. Thus, while Norwegian authorities is trying to provide a safe and reliable transportation system, reduced incentives for new infrastructure investments can be the outcome.

• Løkketangen, Arne; Haugen, Kjetil Kåre; Lanquepin, Guillaume & Olstad, Asmund (2009). Using a set of fixed prices when solving Profit Maximization Capacitated Lot-Size Problems (PCLSP). Full text in Research Archive Show summary

  The Capacitated Lot-Size Problem, CLSP, is central in production planning research, and a lot of publications on this problem exists (see e.g. [2]). Many formulations, variants and extensions exist for this problem. We have previously looked at this problem using a profit maximization formulation instead of the customary cost minimization (see [4]). This work has later been extended by solving larger instances, using heuristics, and adding price limits (see [5]). The reasoning behind these extensions is that instead of having a fixed demand, the actual demand can be influenced by changing the prices for these commodities. This again influences the required capacity. As noted in our previous work, we assume a monopolistic situation. This is somewhat unrealistic, but we argue that our work might be transferable to more realistic (e.g. oligopolistic/gametheoretic) market environments. The main point is that demand can be affected, not necessarily the complexity of the demand description. In [3] the authors argue that there are three factors driving the trend towards demand based management: (1) increased availability of demand data, (2) it is becoming increasingly easier to change the prices, and (3) the increased availability of decision support tools. They claim that dynamic pricing will migrate from the hotel and airline industry to retail and other industries where sellers are able to store inventory. Lee [9] writes: What will be the next competitive battleground in the 21st century? It will be managing the demand for the total value maximization of the enterprize and value chains - Demand- Based management. In our previous work the prices where continuous, and could take on any value within its bounds. This is a somewhat unrealistic condition. It is much more common for most commodities that the prices are discretized, with a certain distance between the price levels. We will look at this case of a fixed set of prices per commodity. Of interest are the consequences of the discretization algorithmically and how the computational results are affected. We will also look at the consequences of the various pricing policies that can be applied. This is work-in-progress. Novel heuristics, based on Tabu Search (see [6]), but also integrating Cplex [1], and classical heuristics based on the Wagner-Whitin [10] and Thomas [8] algorithms as subproblem solvers will be developed. Extensive computational results will be reported, based on (modified) instances from Lotsize-lib [7] and on instances previously published by the authors.

  Traditional sports economic research focuses strongly on sports labour markets, player wages and competitive balance. This line of research stretches back to a paper by Quirk and El-Hodiri [10]. Through redevelopment of this modelling frame, several authors have discussed various extensions to the basic model - see for instance Quirk and Fort [11], Fort and Quirk [3], Vrooman [14], [15], [16], Hausman and Leonard [5], Rasher [12], and Goddard and Dobson [1]. Of special interest in this setting is the work of Stefan Késenne [7], [6], [8], [2] who looks at an extension of the original model of Quirk and El-Hodiri by applying an alternative objective function - win as opposed to profit maximization. Through this grip, Késenne is able to establish equilibria solutions through comparisons of average revenue functions as opposed to the traditional marginal revenue comparisons in the profit maximization case. We, however, propose a direct (simplified) game theoretic approach as an alternative. By doing so, we obtain a framework where similar comparisons may be executed with somewhat different and interesting results. For instance, the choice of objective is important, however not vital. We build our approach directly on preliminary research in a forthcoming article by Haugen and Solberg [4] and seek to extend the relatively simple modelling and conclusions presented here. We will pursue different and more advanced game formulations. Particularly, we will focus on the claimed economic crisis of European football (see e.g. Lago [9] et al) and propose more complex explanatory patterns than objective function choice for observed financial differences between US sports and European football.

The last process type corresponds to continuous process industries that are least researched with respect to specific optimization issues. This disbalance has developed due to traditional contrasting of discrete and continuous environments without a proper differentiation between distinct process industries. In this paper we consider conceptual and optimization issues related to production planning in continuous process industries with nondiscrete products. The purpose of this paper is to locate continuous nondiscrete production within existing theoretical frameworks, discuss general features of continuous process industries and clarify their core production planning characteristics, contrasting them with other manufacturing process types. In particular, we consider a concrete example of a coninuous nondiscrete manufacturing environment to further refine its features and discuss known formalization methods applied to production planning for similar settings, assessing their potential use for the system in question. Finally, we develop a mathematical optimization model for the incumbent production system allowing a better utilization of production capacity with respect to energy costs while synchronizing production and distribution planning in the holistic supply network context.

A significant theoretical basis related to production planning for different manufacturing processes has been established in the extant literature. The classic product-process matrix has been put forward to match the product features with the process characteristics, distinguishing between the four process types: jumbles, disconnected line, connected line, and continuous flows. The last process type corresponds to continuous process industries that are least researched with respect to specific optimization issues. This disbalance has developed due to traditional contrasting of discrete and continuous environments without a proper differentiation between distinct process industries.

  Omya Hustadmarmor supplies calcium carbonate slurry to European paper manufacturers. The products are transported out from a single processing plant. In 2001, the company was facing a situation with overwhelming operational challenges and decided to look for OR-based planning support. Møre Research Molde conducted a project that led to the development of a Decision Support System for maritime inventory routing, providing planners with the necessary support to make stronger and faster decisions. This has increased both predictability and flexibility throughout the supply chain, resulting in direct savings in production and transportation costs of close to $7US million a year. Also projected are additional direct savings of nearly $4 million a year, since even larger ships can be added to the fleet. Investments of $35 million have been avoided due to increased capacity utilization.

  Bosman-dommen skapte store endringer i fotballnæringen med økte lønninger, flere internasjonale overganger og skyhøye overgangsbeløp. Dommen i den såkalte Perugia-saken forventes å falle i løpet av vinteren. Denne kan skape tilsvarende store endringer dersom dagens overgangsbeløp mellom klubbene faller bort. I denne artikkelen drøftes konsekvensene av en slik dom. Spillerlønningene forventes å gå ned i Norge og å gå opp i de rike ligaene som Premier League. Et større lønnsgap mellom norske og utenlandske toppspillere vil gi enda sterkere incentiver for norske spillere å søke ut, og for f.eks Rosenborg kan det bli enda vanskeligere å holde på kvalitetsspillere siden spillerne ikke kan låses i langtidskontrakter, men det kan bli billigere å rektuttere i Norge og lettere å hente hjem igjen de som ikke lykkes ute. Graden av konsentrasjon kan komme til å øke, men her er det litt motstridende effekter og denne virkningen kan dempes med omfordelingstiltak tilsvarende det man gjør i ligaene i USA.

  We use the progressive hedging algorithm (PHA) of Rockafellar and Wets as a meta-heuristic for a stochastic lot-sizing problem with a multi-stage decision process with recourse. We cast the PHA as a meta-heuristic with the sub-problems generated for each scenario solved heuristically. Rather than using an approximate search algorithm for the exact problem as is typically the case in the metaheuristic literature, we use an algorithm for sub-problems that is exact in its usual context but serves as a heuristic for our meta-heuristic. We describe application of our method to the lot-sizing problem, and extend it to also include profit maximization. Computational results demonstrate that the method is effective.

This gives rise to a need for stochastic programming (SP) methods that create solutions that are hedged against future uncertainty. The progressive hedging algorithm (PHA) of Rockafellar and Wets is a general method for SP. We cast the PHA in a meta-heuristic framework with the sub-problems generated for each scenario solved heuristically. Rather than using an approximate search algorithm for the exact problem as is typically the case in the meta-heuristic literature, we use an algorithm for sub-problems that is exact in its usual context but serves as a heuristic for our meta-heuristic. Computational results reported for stochastic lot-sizing problems demonstrate that the method is effective.

  This paper discusses various modelling problems related to the problem of finding an optimal timing of treatment for Musculoskeletal Diseases. Characteristics for these diseases are uncertainty, both regarding diagnostics and treatment effects. As a consequence, methodology from Stochastic Optimisation seems applicable. Some simple modelling examples are given along with some basic solution characteristics. It is shown that under fairly general assumptions, no optimal timing of treatment exists (“bang-bang” solutions). Some approximate optimal solutions for alternative cases are also presented.

  GMS prosjektet "Nyskaping og næringsutvikling i Møre og Romsdal" har hatt sitt faglige fokus rettet mot den videre utvikling av verdiskapingspotensialet i den maritime næringsklyngen i regionen. Arbeidet har vært nær knyttet opp til et langvarig arbeid i fagmiljøet med næringsøkonomiske studier av den maritime klyngen. Utsiktene for den videre utvikling i den maritime næringen etter den globale finanskrisen, har vært et dominerende tema i prosjektet den siste tiden. Arbeidet innen dette prosjektet har gitt anledning til å inkludere sentrale tema som innovasjon og kunnskapsdeling i globale og regionale næringsklynger. Det er i prosjektet utviklet en modell for logistikkplanlegging knyttet til produksjon på ulike geografiske steder og ved bruk av ulik type arbeidskraft. Modellen gir et grunnlag for å drøfte spørsmål knyttet til outsourcing ved produksjon i lavkostland. Det har videre vært arbeidet med å utvikle et beslutningsstøtteverktøy for operasjonell planlegging i prosjektorientert produksjon. Prosjektet har vært gjennomført i tett dialog mellom referansegruppen og prosjektgruppen. Referansegruppen har ut fra sin brede erfaring fra næringen, på en meget konstruktiv måte bidratt til å fange opp sentrale forskningsmessige tema som er av stor praktisk relevans for næringen. Vi ser denne arbeidsformen som et eksempel på et vellykket samarbeid mellom bedrift/næring og forskningsmiljø. Samlet har prosjektet på en meget god måte bidratt til å bygge ut og styrke den samlede forskningskompetansen ved Høgskolen i Molde og Møreforsking Molde AS, på områder av potensiell stor betydning for den videre utvikling i den maritime næringen. Flere av de forskningsmessige temaene som er tatt opp i prosjektet er under videre utvikling gjennom andre prosjekter ved Høgskolen i Molde/Møreforsking. Tilbakemeldingene fra bedriftsrepresentanter er at resultatene fra prosjektet blir oppfattet som relevante og nyttige for å forstå og takle de utfordringene en står ovenfor og gjennom dette bidra til en videre utvikling av verdiskapingspotensialet for den maritime næringsklyngen i Møre og Romsdal.

• Haugen, Kjetil Kåre (2009). Globalisering og logistikkmodeller. Høgskolen i Molde. ISSN 9788279621249. Full text in Research Archive Show summary

  Dette delprosjektet - Globalisering og Logistikkmodeller - har fokusert på kvantitative modeller i logistikk med hovedvekt på modellering av den globale dimensjon. Dette innebærer at problemstillingen knyttet til multilokalisering av produksjon og arbeidskraft har vært i fokus. Til tross for at slike problemstillinger åpenbart har vært aktuelle i flere år, er innholdet i kvantitativ forskningslitteratur innenfor dette problemområdet sparsomt. Riktignok har globalisering og dens konsekvenser vært et "hett" tema i kvalitativ logistikk, men innslaget på den kvantitative siden har foreløpig vært sparsomt. I så måte kan denne typen arbeid vise seg å være viktig, ikke bare som faktisk beslutningsstøtte til aktører i næringslivet, men også som innspill til utvikling av nye forskningsområder i logistikk. Verdien av kvantitativ (matematisk) modellering undervurderes ofte fordi krav om datakvalitet og nødvendige modellforenklinger sjelden gir praktiske modeller som favner nødvendige virkelighetsbeskrivelser. En skal imidlertid ikke undervurdere det prosessuelle knyttet til matematisk modellering generellt og kvantitativ logistikkmodellering spesielt. Ofte vil en slik modelleringsprosess være viktigere enn de modellresultater som foreligger i enden av denne typen prosjekter. Prosessen via forenklinger og diskusjon av tilgjengelige data vil nemlig ofte medføre ny kunnskap som igjen kan lede til kvalitativt nye og forbedre beslutninger i mange praktiske situasjoner. Selve modelleringsprosessen med problemstrukturering og diskusjon av nødvendige datakrav vil dermed ofte kunne ha en egenverdi for bedrifter, selv om det endelige modellresultat ikke alltid medfører operative, kjørbare, implementerte modeller. I rapporten Globalisering og Logistikkmodeller beskrives resultatene av dette delprosjektet. Rapporten faller naturlig i to deler. I første del diskuteres muligheter for å tilpasse en klassisk logistikkmodell - "den aggregerte produksjonsplanleggingsmodellen" - til en mer moderne globalisert virkelighet. Valget av aggregert produksjonsplanlegging falt egentlig naturlig, ettersom denne modellen bl.a. fokuserer på planlegging på mellomlang sikt der også mannskapsressursen og håndtering av denne omfattes av sentrale beslutningsvariable. Ettersom en interessant vinkling i moderne globalisert produksjon er tilordning av arbeidskraftressurser over flere arbeidsmarkeder falt det altså naturlig med et slikt utgangspunkt. Som antydet ovenfor, behandler første del av delprosjektet ulike versjoner av denne planleggingsmodellen. Bl.a. diskuteres muligheter og begrensninger knyttet til en mer eller mindre avansert kobling mot arbeidsmarkeder i form av to ulike modellkonsepter, en lineær programmeringsmodell og en utvidet ikke-lineær versjon der modellen åpner for at forbruk av arbeidskraft kan påvirke lønnsnivået. Et annet hovedfokus i modellene er multilokasjon av produsentressursen. Så litt populært kan en si at disse modellene søker å beskrive hvordan en gitt predikert framtidig etterspørsel skal tilfredsstilles kostnadsoptimalt dersom en tillater bruk av arbeidskraft og produksjonsressurser fra ulike markeder (ulike geografiske lokasjoner). I andre del av rapporten fokuseres det på den enkleste av de to modellene diskutert foran, den lineære programmeringsmodellen. Denne fullspesifiseres, og klargjøres for datamaskinell løsning. Avslutningsvis anvendes denne denne beskrivelsen konkret i noen enkle eksempler for å antyde modellens bruksmuligheter. Spesielt fokuserer denne eksemplifiseringen på problemstillingen "utflagging". Dette velkjente og tidvis offentlig aktuelle problemkomplekset illustreres enkelt ved tomarkedseksempler - et "hjemme"- og et "utemarked". Resultatene fra disse simuleringene (konstruerte inndata) er forsåvidt forutsigbare, men allikevel interessante. En åpenbar konklusjon som kan trekkes er manglende direkte utflaggingstilbøyelighet.

  This paper addresses effects caused by the transition from a 2-1-0 to a 3-1-0 award system in soccer. The first part of the paper discusses consequences of the transition on offensive vs. defensive play. This part may be seen as a valuable supplement to work by Carillo and Brochas [2] as the choice of a different game theoretic framework provides increased insight into the concept offensive/defensive play in soccer. The second and main part of the paper addresses additional effects included by the award system transition - especially effects on competitive imbalance. It is shown by simple game theory that under a relatively general set of team descriptions, such a transition may affect competitive balance adversely. In final sections of the paper some empirical examples strengthens the hypothesis on adverse competitive effects.

  Observeres transportmarkedet i Norge, vil en raskt se at svært mye av transporten utføres ved hjelp av bil. Store deler av fiskeeksporten anvender eksempelvis denne transportformen. Denne typen tilpasning kan, under forutsetning om eksistens av stordriftsfordeler i favør av båttransport synes vanskelig forklarbar. Hovedformålet med denne rapporten er å forsøke å forklare denne typen tilpasning ved hjelp av enkel spillteori. Hovedkonklusjusjonen må sies å være at vi - ved hjelp av enkle spillteoretiske modeller - har vært i stand til å gi en type forklaring på hvorfor biltransport framstår som et gunstig alternativ i sammenlikning med båttransport. Det er i hovedsak to typer effekter som bidrar til denne konklusjonen. Den ene effekten omtales som "Prisoner's Dilemma"-effekten, mens den andre omtales som "Fleksibilitetseffekten". "Prisoner's Dilemma"-effekten innebærer at et sett av aktører som spiller mot hverandre i et spill kan tenkes å realisere et løsningspunkt som individuelt og samlet sett ikke er det gunstigste. Dette er en kjent effekt, og vår vinkling innebærer i prinsippet ikke annet enn modellering, identifikasjon og analyse av denne effekten. De praktiske implikasjoner av denne typen effekt, innebærer at dersom regulerende myndighet (staten) skulle ønske - f.eks. av miljøhensyn - å befordre substitusjon fra biltrafikk mot sjøtransport, er det ikke tilstrekkelig å sørge for at båttransport er billigere enn biltransport. Et annet viktig poeng i arbeidet er eksistens av multiple likevekter. I praktiske termer innebærer dette at det er vanskelig å spå resultatet av den typen spillsituasjoner vi har modellert. For praktiske reguleringsformål vil disse to konklusjonene samlet sett bety at etablering av fornuftige reguleringsmekanismer vanskeliggjøres. Etablering av et sett av nye havner i Norge med sterkt subsidierte transportkostnader behøver altså ikke å lede til redusert biltransport."Fleksibilitetseffekten" innebærer introduksjon av usikkerhet. Her modellerer vi eksplisitt usikkerheten i form av sannsynlighetsfordelinger for aktørenes vurdering av framtidig transportmengde/destinasjon. Den spillteoretiske effekten av denne introduksjonen innebærer endring (fra den deterministiske situasjonen) i retning av økt tilbøyelighet mot valg av bilalternativet. Dette er rimelig intuitivt ettersom bil som transportmedium klart har bedre fleksibilitetsegenskaper. Dette gjelder både fordi kostnadseffektive båtløsninger innebærer koordinasjon - som i seg selv innebærer infleksibilitet - men også infrastrukturelle fordeler knyttet til bilmediet. (Det finnes normalt flere veier langs bakken til en destinasjon enn via havet.) Som en burde forvente, vil tilbøyeligheten til realisasjon av bilalternativet øke med økende usikkerhet. (Verdi av fleksibilitet øker som kjent med økt usikkerhet). Sammenholdes disse effektene kan vi altså konkludere med at sterke krefter virker i retning av økt biltrafikk. Spesielt synes dette å være tilfelle dersom en tror at framtida vil by på økende grad av usikkerhet knyttet til norske bedrifters etterspørselssituasjon. Dette kan vel neppe sies å være en kontroversiell hypotese dersom globaliseringen øker. En naturlig konsekvens av økt globalisering er som kjent økt konkurranse, noe som med rimelig grad av sikkerhet også vil lede til økende usikkerhet for avsetning av norske produkter. Spesielt problematisk synes denne framtidsvisjonen å være for Norge fordi en større andel av totale produksjonskostnader er knyttet til transport hos oss enn f.eks. I de fleste EU-land. I så måte vil et statlig styrt forsøk på å øke graden av godstransport med båt innebære en svært risikabel strategi. Et annet poeng knyttet til denne tankerekken er forståelsen av at ulike markeder vil ha ulike egenskaper. ... (Sammendraget er forkortet).

  A meta-heuristic is often defined as a heuristic algorithm that controls and guides underlying heuristics applied to a problem. We use the progressive hedging algorithm (PHA) of Rockafellar and Wets as a meta-heuristic for a stochastic lot-sizing problem with a multi-stage decision process with recourse. We cast the PHA as a meta-heuristic with the sub-problems generated for each scenario solved heuristically. Rather than using an approximate search algorithm for the exact problem as is typically the case in the metaheuristic literature, we use an algorithm for sub-problems that is exact in its usual context but serves as a heuristic for our meta-heuristic. We describe application of our method to the stochastic lot-sizing problem, and extend it to also include profit maximization. Computational results demonstrate that the method is effective.

  Voksende oppmerksomhet omkring miljøspørsmål gjør det naturlig å undersøke hvordan logistikkmodeller kan modifiseres for å kunne fungere under nye rammebetingelser som følger av økt miljøfokus. Logistikkmodeller er i denne rapporten definert som det analytiske og numeriske apparat som gir beslutningsstøtte til bedriftsinterne prosesser relatert til materialflyt. Det er fokusert hovedsaklig på de tre tradisjonelle emneområdene innenfor logistikk, nemlig innkjøp/lager, produksjon/lager og transport. Rapporten er delt i to hoveddeler: Første del er en omfattende litteraturoversikt. Det er fokusert på tre ulike tilnærminger til miljøproblematikken, henholdsvis modeller for avfallsbehandling, modeller for gjenvinning og mer gjennomgripende modeller som inkorporerer redusert ressursbruk. Andre del av rapporten er analysedelen. Her blir hovedfokus satt på hvilke konsekvenser offentlige reguleringer i form av henholdsvis miljøbeskrankninger og miljøavgifter vil ha for bedrifters logistikkfunksjon. Virkning på tradisjonelle deterministiske og stokastiske styringsmodellers kompleksitet av henholdsvis miljøavgifter og miljøbeskrankninger analyseres. Resultatene viser at mens en innføring av en miljøavgift bare medfører en justering av inputparametre i modellene, så vil en innføring av nye beskrankninger implisere en økt kompleksitet som gjør at utskifting av eksisterende styringsmodeller ikke er til å unngå. Tradisjonelle modeller finnes i dag innebygget i de fleste styringssystemer. En oppgradering for å takle ekstra miljøbeskrankninger kan medføre betydelige kostnader i form av programutvikling, konsulenthonorarer og opplæring. Avslutningsvis introduseres en ramme som kan brukes til å modellerer markedsrelaterte problemstillinger knyttet til assymetrisk informasjon og markedskobling. Assymetrisk informasjon betyr i dette tilfellet at produsent og konsument har svært forskjellig kunnskapsnivå når det gjelder et produkts virkelige miljøegenskaper. Markedskobling gjenspeiler at lønnsomheten av en bedrifts "grønne" tiltak også vil være avhengig av konkurrentenes atferd.

  Observeres transportmarkedet i Norge, vil en raskt se at svært mye av transporten utføres ved hjelp av bil. Store deler av fiskeeksporten anvender eksempelvis denne transportformen. Denne typen tilpasning kan, under forutsetning om eksistens av stordriftsfordeler i favør av båttransport synes vanskelig forklarbar. Hovedformålet med denne rapporten er å forsøke å forklare denne typen tilpasning ved hjelp av enkel spillteori. Første delen av rapporten tar utgangspunkt i et to-spillers spill der aktørene velger binært og simultant mellom sjø- eller biltransport. Her formuleres ikke transportbehovet som et resultat av produksjon, men reultatene kan allikevel gi intuisjon knyttet til hovedproblemstillingen. I andre del av rapporten behandles tilsvarende situasjon men med transportbehov som et resultat av produksjon i en duopolsituasjon. I dette spillet velger aktørene transportmode i første trinn og produksjonskvanta i andre trinn. Valgene på hvert trinn utføres simultant. Et element som forfatterne anser som viktig i en eventuell forklaringsmekanisme - usikkerhet knyttet til transportbehov/transportmuligheter - er delvis behandlet i tredje del. Et poeng i en slik sammenheng vil være at fleksibiliteten til et bilalternativ både med hensyn til behov og muligheter åpenbart er større. I så måte vil dette klart kunne trekke i retning av bilalternativet som et fornuftig valg for aktørene. I siste delen av rapporten endres fokus noe fra spill-modeller med få aktører til likevektsmodeller med mange aktører. Her presenteres en modell basert på Mohrings arbeider. Rapporten er skrevet som en forprosjektrapport på oppdrag av Norsk Forskningsråd.

  Denne rapporten omhandler ulike algoritmiske løsninger på det problemkompleks som litt løselig kan karakteriseres som profittmaksimerende produksjons- og lagerstyringsmodeller under usikkerhet. Hovedresultatene fra arbeidet kan oppsummeres i form av to foreslåtte algoritmer. Den første algoritmen (heurestikk) søker å løse et klassisk en-produkts "Lot-size" problem med usikker etterspørsel. Det metodiske grep som anvendes er den såkalte "Progressive Hedging" algoritmen. Den rapporterte heurestikk gir svært raskt svært gode løsninger sammenliknet med alternativ programvare. Eksempelvis rapporterer vi en hastighetsforbedring i størrelsesorden 1000 ganger for rimelig store case. Det andre hovedresultatet er konsentrert rundt utvikling av en algoritme for løsning av "CLSP"-problemet med profittmaksimering. Dette problemet - uten profittmaksimering - er en klassiker i "Lot-size"-litteraturen, og en hovedhypotese i denne delen av prosjektet har vært: a) Introduksjon av profittmaksimering gir mulighet for raskere løsning enn i kostnadsminimeringstilfellet. b) Introduksjon av profittmaksimering gir bedre og mer realistiske modeller for næringslivet. Vår foreslåtte algoritme gir bekreftende indikasjon på hypotesen i a). Algoritmen er riktignok ikke testet ut i full bredde, prosjektrammen ga ikke mulighet for dette, men all numerisk testing så langt tyder på at basishypotesen er rimelig. Det har ikke vært en klar målsetting å foreta konkret empirisk vurdering av hypotese b), men samtaler med en rekke aktører i næringsliv og forvaltning indikerer at behovet for denne typen modellering er stort.

  Denne rapporten beskriver sentrale emner knyttet til modellering av verdikjeden ved salg av norsk naturgass. Rapporten faller naturlig i 3 deler. Første del diskuterer eksisterende modellers styrke og svakheter i relasjon til den aktuelle problemstilling. Andre del diskuterer problemstillinger relatert til lagring av gass mens siste del diskuterer markedssiden. Framstillingsformen er med hensikt diskuterende. Dette innebærer at rapporten ikke nødvendigvis gir svar på hvilket modellkonsept som bør benyttes ved modellering av gasskjeden. Rapporten diskuterer imidlertid sentrale problemstillinger en bør ta stilling til dersom en ønsker å gjennomføre en slik modellering. I så måte bør rapporten ses som et første skritt på veien mot en akseptabel modellstruktur.
