  This study explores how knowledge co-creation in the learning process is affected and facilitated by digital technologies, in particular 3D printing and RFID reading. A qualitative single-case study presents the learning process in class based on a model of intermodal transportation with RFID reading and 3D-printed objects. Data from five semi-structured interviews, questionnaires, situation observations in three experiential labs, and archival materials are interpreted through the experiential learning approach to emphasize the role of 3D printing in learning and knowledge creation. The study reveals how digital technologies transform the learning process to help students develop practical skills in the supply chain management (SCM) field. The active experimentation further shows that the use of 3D printing and RFID reading encourage meaningful communication between students and lecturers and increases students’ active engagement in learning and knowledge creation. The findings reveal that the learning process in the digital era becomes transformed into increasingly new forms of integrative knowledge and competence, emphasizing practical and technical skills. It results in a shift from passive to active learning or from a teacher-centered to a student-centered approach to developing students’ practical skills for companies’ needs when adopting new technology in practice. The study shows the potential of digital technologies for further adoption in SCM and logistics curriculums beyond the so-called STEM disciplines. More empirical studies applying experiential learning are suggested on how learning from formal education and so-called strategic learning from companies’ experience can be integrated into the process of knowledge co-creation based on digital technology.

  The literature on product variety provides great insights into various businesses. However, little research has been conducted on product variety in the healthcare industry. This study aims to explore the influence of product variety on inventory in hospitals. Since most hospitals are known to replenish products using a homegrown ad-hoc system, a model is developed for exploring all possible product combinations and substitutions. This article presents the behaviour of product substitution, which may be either one-to-one or many-to-one for both sterile and non-sterile products, in the hospital with cost factors. It discusses the product variety reduction and its corresponding cost impacts. The data on a hospital inventory over the course of six years has been procured from a hospital in Norway. Based on the results, the hospital could have a potential product variety reduction of approximately 11% and cost savings from the spending of approximately NOK 3.6 million. Reducing the variety of products in hospital inventories proves to be an approach to reducing costs. The model developed for the research is universal in nature and could be used in other fields, such as retail, marketing etc.

  Waste electrical and electronic equipment (WEEE) as a reverse supply chain (RSC) has a low degree of circularity, mainly focusing on recovering or recycling. Targets to increase the circularity have recently been introduced in the EU WEEE directive. In this case study, we have investigated how WEEE is handled within an electric and electronic (EE) equipment manufacturer. The case study includes findings from two different Nordic countries, Norway and Denmark, with interviews of six stakeholders. The case study shows that there are significant differences in how the case company fulfills its extended producer responsibility (EPR), especially related to reporting. The study also found that there is a mismatch between the ambitions in the WEEE directive and a company’s approach related to circularity in the end-of-life phase of an EE product. Based on the results of this case study and from the literature we propose recommendations on alignment with other directives and on a common information regime within the WEEE RSC. Keywords: waste electrical and electronic equipment (WEEE); product information flow; reverse supply chain; manufacturer; circularity.

  ERP implementation is a complex and expensive project for organisations because it touches upon social, behavioural and technical issues. This article presents an in-depth case study of an ERP consultancy in order to comprehensively understand ERP implementation from the consultancy’s perspective. Interviews were conducted with consultants, project managers, senior managers and other employees. The interview responses indicate that both the client and the consultancy measure success in terms of quantifiable units of time, cost and scope. In addition, qualitative measures of client maturity and client satisfaction are central to achieving project success for the consultancy when implementing ERP systems. Through incorporating critical success factors (CSFs) in the project methodology, the consultancy can ensure repeatable implementation processes, which contribute to a higher probability of success for both the consultancy and its clients. This study contributes by identifying consultancy CSFs: project management, IT environment, training and education, change management, and maintenance and support. Furthermore, the client’s maturity, and the management of client expectations are identified as unique CSFs for the ERP consultancy. This study will be beneficial for ERP consultancies, practitioners and researchers.

  There has been a strong growth in aquatic products supported by the global seafood industry. Consumers demand information transparency to support informed decisions and to verify nutrition, food safety, and sustainable operations. Supporting these needs rests on the existence of interoperable Internet of Things (IoT) platforms for traceability that goes beyond the minimum “one up, one down” scheme required by regulators. Seafood farmers, being the source of both food and food-information, are critical to achieving the needed transparency. Traditionally, seafood farmers carry the costs of providing information, while downstream actors reap the benefits, causing limited provision of information. Now, global standards for labelling, data from IoT devices, and the reciprocity of utility from collecting data while sharing them represent great potential for farmers to generate value from traceability systems. To enable this, farmers need an IoT platform integrated with other IoT platforms in the value network. This paper presents a case study of an enterprise-level IoT platform for seafood farmers that satisfies consumers’ end-to-end traceability needs while extracting data from requests for information from downstream actors. Keywords: IoT platform, seafood traceability, seafood farmer, reciprocity, supply chain, value

  Manufacturers in the oil and gas industry face increasing documentation requirements of assets for compliance, quality assurance and contractual purposes. The documentation includes hundreds of documents for each asset that are compiled into a Manufacturer Record Book (MRB) to be delivered with the asset. The MRB is created by collecting all necessary documents and storing them in the MRB as scanned copies in PDF format. Creating an MRB is a cumbersome, error-prone and time-consuming activity. Using an MRB in PDF format is equally hard as it requires humans to search and extract data. Several initiatives have been undertaken by joint industrial projects and standardization agencies to represent the documents by their data in a language understandable to computers and humans. It has been proven that ontologies are effective tools in digitalization by making data from diverse sources interoperable. This paper presents a case study of MRB digitalization for CodeIT, a company developing software solutions for industrial applications. The focus is on creating an ontology for a welding certificate, following an Extract-Transform-Load (ETL) procedure that extracts data from a welding certificate in PDF format and uses the ontology for transforming the data into subject-predicate-object triples in a Resource Description Framework (RDF) model. The results demonstrate the applicability of ontologies for digital transformations. Keywords: manufacturing record Book, ontology, interoperability, FAIR principles, digitalization

  Purpose Most companies include a commitment for sustainable growth involving a switch towards the circular economy (CE) model. The purpose of this paper is to present barriers to CE adoption identified by a literature review. The paper also addresses the particular challenges faced by manufacturers by answering the research question: What are the dominant barriers faced by the manufacturing industry in moving towards a CE? Design/methodology/approach This paper presents a literature review of research identifying barriers for adopting to CE in the manufacturing sector. The literature review is followed by a case study identifying barriers to CE as seen by ten companies within manufacturing, including the GS1 global information standardisation agency used by all manufacturers. Findings The manufacturers investigated focus mostly on recycling and waste reduction. These policies have low or very low CE effect. High CE effect policies like maintenance and reuse targeting the CE ideal of no waste, are nearly non-existent. The results identified seven main barriers to the CE: (1) high start-up costs, (2) complex supply chains, (3) challenging business-to-business (B2B) cooperation, (4) lack of information on product design and production, (5) lack of technical skills, (6) quality compromise and (7) disassembly of products is time-consuming and expensive. Research limitations/implications The data come from participants in a single country, Norway, although the manufacturers are multinational companies adhering to enterprise policies. Practical implications This research shows that all the companies interviewed are well aware of the growing need for their company to move towards more sustainable operations involving CE concepts. The barriers identified are explored, and the findings could guide such companies in their efforts to move to maintenance, reuse, remanufacture and recycle (M+3R) operational model. Social implications The study has found that the major barriers for implementation of CE are quality issues in recycled materials, supply chain complexities, coordination problems between companies, design and production of the product, disassembly of products and high start-up/ investment costs. Originality/value The research shows how the transition towards a CE takes place in manufacturing industries by studying the manufacturing sector.

  Moving towards more sustainable operations is a challenging goal for industries. The growth of interest in corporate sustainability performance has brought attention to the importance of accounting and transparency across economic, environmental and social dimensions. This paper provides an explorative study addressing sustainability from the perspective of industrial firms. The paper presents case studies on the application of the Triple Layered Business Model Canvas, which allows for relevant insight into how firms account for economic, environmental and social values. The findings show that while accounting for economic values is well taken care of, accounting for environmental values are at an initial stage, and accounting for social values are virtually lacking. Thus, the ability for the industrial firms to conduct a sustainability assessment is limited. The opportunities lie in the adaptation of digital technologies providing cost efficient feedback mechanisms for environmental and social values. This can support environmental and social accounting, giving industrial managers a decision management tool to guide their transition towards more sustainable operations, and aligning company goals with the UN Sustainable Development.

  The manufacturing industry has to withstand an increasing competition requiring customization of products, shorter time to market and a transition towards more sustainable operations and products. There is a need for a transition to business models that incorporate sustainability while keeping business activities profitable. Leveraging the advantages of new technologies within the concept of Industry 4.0 is seen as an important factor to maintain competitiveness while responding to the sustainability challenge. Changing the way businesses operate is not easy as is evident from studies that have identified many barriers, including costs, lack of competence, loss of jobs, and process, product or production facilities not suitable for Industry 4.0. Due to these barriers, firms are slow to make a transition towards customized products, shorter lead times and more sustainable operations and products. The commitment for sustainability includes a shift towards Circular Economy (CE) that poses additional barriers like geographic dispersion, product complexity, and lock-in to the contemporary linear ‘take-make-consume-dispose’ model of operation. This paper addresses how manufacturers perceive Industry 4.0, what motivates their investments in Industry 4.0, and what barriers they see in adapting Industry 4.0 followed by a literature review identifying barriers for adhering to CE in the manufacturing industry sector. The study offers empirical insights identifying a need for a roadmap for implementation of Industry 4.0 to support CE as well as providing directions for future research.

  In this paper, we explore the use of network routing for production planning and control in manufacturing of complex industrial products. Such a product is the result of a joint effort of many manufacturing companies; each considered a collection of work centre nodes connected by transportation links forming a company-wide manufacturing network. Each company is, in turn considered a manufacturing node connected to other manufacturers by transportation links forming a distributed manufacturing network that produces the final product. We model the manufacturing network as a distribution network where the incoming and outgoing inventories of products are distinct nodes in addition to the work centre nodes. Production planning and control are done by minimizing the cost of handling all products in all work centre nodes. This formulation provides a scalable and flexible production planning and control scheme adhering to the networked structure of manufacturing of complex products. We apply the model to a company-wide manufacturing network as a first approach. A case study using the model demonstrates production planning using network routing at a manufacturer of ship propulsion engines.

  Business decision-making is based on a combination of explicit and tacit knowledge. Tacit knowledge is difficult to codify, manage and share in the same manner as explicit knowledge. The ability to share tacit knowledge offers great value to an organisation. The growing level of global business activities leads to an increasingly competitive environment with a greater demand for communication of tacit knowledge over distance. This chapter presents a study of the suitability of virtual-worlds for business decision-making over distance involving the exchange of tacit knowledge to support decisions at the tactical and strategic management layers. The avatar, being the primary interaction object in virtual-worlds, forms the basis of a model of the role concept in user-to-user communication. We present a case study showing how the selection of an avatar reflects the user’s role, and how an avatar situates the user in a business environment. Our study shows that virtual-worlds support the mediation of tacit knowledge. This is contrasted with state-of-the-art enterprise business systems commonly used for business transactions based on explicit knowledge exchanged over distance. The avatar is found to fulfil the role of the communicator and the role expectations from real-life situations. Our findings show that virtual-worlds have unique properties in supporting tacit knowledge exchange required for decision-making in a distributed business environment.

  The growth in world trade is doubling every 5-7 years with a corresponding increase in cargo container movements most of which are handled by seaports. Moving more traffic through the limited area of a seaport can only be achieved by an increase in port performance. Ship owners, terminal operators and forwarding agents each have optimized their performance guided by values collected on key performance indicators. However, our results from a case study at Oslo port shows that operations suffer from insufficient information sharing resulting in an unused integration potential which not captured by the current performance indicators. We propose a new Information Sharing Indicator calculated as the sum of zero/one variables showing whether electronic information sharing between actors is shared (1) or not shared (0), plus with a value metric measuring the level of the information shared on a scale from 1 (lowest) to 3 (highest). We propose to extend the multi-dimensional port performance measurement framework commonly used by ports by extending it with the Information Sharing Indicator.

  The LogisticsHub is an event tracking solution to manage information of cargo carrying units (CCUs) and their content along the upstream oil and gas supply chain. The main objective is to facilitate the best possible flow of information between the companies in the oil and gas sector related to offshore upstream oil exploration and production activities. The LogisticsHub uses the EPCIS (Electronic Product Code Information Service) standard by GS1 for tracking events and for creating dashboard applications accessing the data. In the first version the focus is on tracking CCUs (cargo container units), while in the second version also the content of the containers will be tracked. The increased visibility enables enhanced performance of actors along the chain. In this paper we show how the overall complexity of multi-party information flows is reduced by the introduction of hubs, and how this contribute to improve performance of the supply chain as a whole and for each actor. Each actor in the supply chain generates tracking data into the LogisticsHub in a push fashion. The data enables the parties to evaluate their performance based on actual location data, and enhances the resilience of the supply chain. Based on lessons from the early stages of the EPIM LogisticsHub solution we evaluate the relevance of this design in a more general intercontinental container supply chain setting. The LogisticsHub solution is contrasted with the data pipeline concept being based on a pull approach to gather tracking data. The data pipeline has been developed under the recent EU-funded Cassandra project.

  Streamlining the operation of the extended global supply chain is challenging since it involves a multitude of information systems and companies in several countries. Academia partly fails to fulfill the demand for candidates with the knowledge and skills for executing international business transactions. Consequently, we lack candidates who can translate theory into actions, thereby creating a knowledge-doing gap. This paper contributes to bridging this gap by introducing a new learning activity: the global supply chain learning activity denoted as the GSC-Activity. The GSC-Activity lets students execute export and import transactions in an international business-to-business environment involving several companies while handling both the inter-company order flow and the internal order management cycles at each company using their ERP system. This provides student with deep exposure to the information flow along the chain and experience in executing export and import processes of each company. We provide a workable example of the GSC-Activity with a case study repeated over several semesters involving students from Australia and Norway.

  In his article we explore how educational institutions are faced with changes in the modern global business environment, and how this leads to need for changes in curricula for business schools and information systems schools. Most of academia still uses a strict disciplinary model of education resulting in a high degree of specialization within each discipline while the modern business environments require knowledge workers who can address problems that cut across disciplines on an increasingly global scale. Research papers and governmental reports call for more emphasis on particularly three interdisciplinary topics; 1) competencies in globalization issues, 2) communication/working in team, and 3) information literacy. The disciplines of business and in particular information systems education have received much attention in this respect with several calls for change. How to bring about such a change is, however, still an open question. This paper proposes to address this issue in two ways; by suggesting two new educational activities and by proposing a new educational interdisciplinary competency framework to guide curriculum development when including interdisciplinary topics.

  This paper describes the use of a virtual world environment to facilitate a role play assignment for buying and selling Enterprise Resource Planning (ERP) software solutions in a distributed environment. The exercise involved the use of Second Life to facilitate the virtual presentation and meeting among the vendors and the purchaser of the software. Students playing vendors and purchase roles were organized into teams who meet, collaborate, and negotiate business transactions in the virtual environment. The aim of the experiment was to introduce students to properties of ERP-systems which are the most common software systems used by businesses, and at the same time introduce tools for virtual team collaboration in an international setting between students in Norway and Australia. This paper reports the experiences from the students’ and teachers’ perspectives and we give recommendations regarding the use of Second Life in role-playing exercises.

  There is significant growth in global business operations and ERP systems are deemed as important applications in order to unify and improve fragmented and globalised markets. These systems are complex and students struggle to grasp not only the underlying business concepts but also the technology involved. This paper describes the design and implementation of teaching materials for a multinational cross-company collaboration assignment using a commercial ERP system. It includes elements of i) integrated business processes, ii) globalization and iii) experiential learning in Masters courses at two universities - one in Australia and the other in Norway. We discuss the lessons learned from the pilot study including the development of an evaluation tool, inter-university student communication, evaluation of the learning outcome, and the benefits of the cross-country business role play exercise.

  Many universities and colleges are investing in teaching and learning developments in virtual worlds despite a lack of any clear guidelines or rules for when virtual worlds will provide benefits over established communication media. Among activities that have been successfully tried out so far are interpersonal role play and oral language education, while other practices like traditional lecturing and business transaction orientated role plays seem to be less suitable for successful implementation. Our objective in this paper is to develop an evaluative framework educational for educational activities in virtual worlds based on Media Richness and Task Closure Theories from Management Information Systems. We demonstrate the use of the framework for three educational activities conducted in the Virtual World of Second Life.

  In this paper we consider the problem of rerouting after a failure in MPLS based networks. MPLS technology enables scalable VPNs and end-to-end QoS over the Internet which requires efficient fault recovery in presence of link or node failures. A major factor on network performance in connection oriented packet switched networks is the transient congestion that results from restored Label Switched Paths trying to retransmit packets lost since the failure. We focus on the step in the restoration process where new recovery paths are selected, and we discuss various strategies for picking paths in order to reduce the transient effects on network performance after a failure. We present results from a simulation-based performance study of four routing algorithms. The results show that using dedicated fault recovery routing algorithms can improve MPLS-network performance after a failure compared to steady state algorithms.

  This paper reports on findings of two surveys conducted in April 2001 and November 2002 on broadband infrastructure and utilization of ICT services in 38 local governments of one county in Norway. Services include internal administrative services for the employees and services to the residents of the communities. We examine how well actual adoption of services had met with expectations. Findings show adoption and use was not as pervasive as expected. Our study is compared to several other regional area studies carried out in Spain. We conclude this can be an inhibitor to this area's regional economic development.

  Connection oriented quality-of-service (QoS) based networks offer several service classes each designed to handle connections supporting various types of applications. A network failure will typically result in a large number of disrupted connections in each service class, all of which need to be restored simultaneously. In this paper we propose a distributed fault recovery priority scheme for dynamic restoration of connections. The proposed scheme exploits available network resources immediately after a failure together with properties of typical applications carried by the connections in order to give the applications sufficient network performance. The scheme is formulated within the context of switched virtual circuit routing in ATM networks, but it is applicable to ATM virtual path restoration as well and to other class based QoS networks like DiffServ MPLS based networks. The priority based restoration scheme is formulated as a centralized path flow integer programming optimization problem serving as a comparison benchmark for suboptimal distributed schemes. We propose a distributed heuristic scheme and give numerical results illustrating the quality of the proposed distributed scheme in comparison to the centralized optimal approach. Our numerical results show that the proposed distributed scheme can significantly improve utilization of network resources and enhance network performance after a failure.

  Industrial manufacturers are moving to a digital world driven by rapid technological developments and the need for costs reductions. Industry 4.0 technologies give more information on most aspects of industrial production, including the inventory management process. This paper investigate how digital technologies of Industry 4.0 can provide information that support the claim that information substitute inventory. This is linked with a case study investigating how a manufacturer use information to manage their current inventory. The findings show a potential to reconsider inventory management strategies in general, and that the manufacturer studied have challenges that can be alleviated by adhering to the information handling strategies identified.

  Most companies include in their strategy, a commitment for sustainable growth which involves a switch towards a circular economy (CE). A CE transition is hindered by barriers that must be overcome to comply with sustainable growth. In this paper we identify barriers faced by industries, and we propose solutions for how to overcome these barriers. The main barriers were found to be complexities in supply chain, coordination problems, quality issues, little attention to CE in production and design, difficulties in disassembly of products and high start-up costs. To overcome these barriers, we present a model supporting life cycle information. Keywords: circular economy, sustainability, barriers

  The two facilitators analyzed a case study of the Ethiopian Public Health Commodity Supply System (EPHCSS) which is supplying more than 3000 health institutions all over the country. The supply network actors are manufacturers, third party transportation providers, the governmental Pharmaceuticals Fund and Supply Agency (PFSA) with a central hub, 11 regional hubs and 7 subhubs, and the health institutions. Process and activity flows of the supply network was mapped in a process model to get a thorough understanding of the EPHCSS. Analysis of the model identified tension points relating to each of the supply chain challenges- stock outs, overstock, counterfeit products and inefficient recalls. To analyze the tension points identified, data was collected using a triangulation of interviews of actors in the supply network, standard operating procedures, and the authors work experience in the Ethiopian health supply system. Based on the process model and the analysis, we identified the potential for mitigating supply chain challenges by enhancing visibility. Based on the insight of the case study, the constraints of the Ethiopian supply system, references to similar projects, and cases from literature; improvement recommendations are suggested. Finally, those improvement recommendations are analyzed for a fitness of relevance using supply chain visibility scorecard methodology.

  As a key motivation to explore approaches to improve supply chain performance, SCV measures can tell where to put the focus. SCV is rated as the most important measure for supply chain performance both by business leaders and researchers. In a wide perspective, authors define SCV as the ability of a focal company and related actors within a supply chain to capture, share, integrate, and create intelligence from key information, or making that information ready for monitoring, controlling, changing or decision making purposes.GS1 define SCV as “the awareness of, and control over, specific information related to product orders and physical shipments, including transport and logistics activities, and the statuses and events and milestones that occur prior to and in-transit”. Therefore, being able to efficiently measure and know the status of this influential aspect-SCV-in a given pharmaceutical supply chain has a significant value for benchmarking or improvement purposes.

Businesses increasingly operate in a global competitive environment use Enterprise Resource Planning (ERP) systems to support their operations. ERP-systems are cross-functional solutions primarily developed to support and automate internal operations of an organization. Businesses being part global supply chains use their ERP-systems to support their export and import operations. Competition among supply chains leads to a focus on efficient crossenterprise operations. Businesses need an end-to-end view of their supply chains to optimize their behavior. The exercises in this paper demonstrate in detail how to execute export and import operations in the SAP ERP ECC 6.0 system in a sample global supply chain.

  This paper outlines the problematic of information and communication aspects of logistics operations and their significance for managerial decision making from the systems model point of view. The systems model view supports understanding in a holistic and interdisciplinary way when doing research of complex organizational systems such as supply chains. We analyze the stages in decision making in an organization that is a part of a supply chain using the systems thinking framework's five phases A-B-C-D-E. Our analysis clarifies what factors are influencing decisions in complex supply chains. The second part of the paper looks at decision making from the Data-Information-Knowledge-Wisdom Model point of view outlining the relationship between hard and soft inputs to the decision-making process. Our analysis contributes to a better understanding of the significance of information in managerial decision making in supply chain operations. The third and last part of the paper is a case study the design to research the decision making process in four manufacturing companies in Norway in the light of the A-B-C-D-E and Data-Information-Knowledge-Wisdom systems models.

  The goal of this research is to develop and evaluate a curriculum that teaches ERP concepts and skills using hands-on practical tasks in a globalised context. The curriculum employs Kolb's experiential learning cycle to facilitate student learning about the issues associated with internationalisation and globalisation of business operations and the use of ERP systems. A small pilot study was undertaken to test the assignment and logistical arrangements with some students undertaking an international inter-group collaboration. Students in Australia and Norway play alternating customer and vendor roles in business transactions recorded on a SAP ERP system. A pre- and post-survey (based on a previous instrument by Seethamraju) evaluated students' perceived knowledge gain across five different areas. The Norwegian students showed only a minor gain in perceived knowledge whilst the Australian students showed significant gains. Students involved in the inter-group (international) role play showed better understanding of the transactional aspects of business operations that those who did not.

  This paper gives the detailed results of a pilot study investigating the use of the 3-dimensional virtual world Second Life for role play exercises in the courses LOG505 Purchase Management and BØK700 Enterprise Resource Planning (ERP) with SAP. Molde University College teaches LOG505 in three different cities; Molde, Ålesund and Kristiansund using videoconferencing equipment, while BØK700 is thought on campus in Molde. Purchasing decisions are made based on both explicit and tacit knowledge. The purpose of the role play exercise is to give students an introduction to the purchasing decision process including the importance of teams, explicit and tacit knowledge and to teach the students basic characteristics of ERP-systems. The role play includes a high degree of simultaneous personal interaction called for in purchasing negotiations. This is not well supported by current videoconferencing tools. Running the role play on-campus in a classroom has drawbacks as well. Given the promising results reported from using virtual worlds like Second Life for role plays we decided to use Second Life to run the role play both for BØK700 and LOG505. The role play is embedded into the courses by going through a pilot study and a full scale study. This paper reports findings and lessons learned from the pilot study and it gives recommendations for the full scale study.

  This paper considers the effects of dynamic restoration routing after a failure in MPLS based networks. MPLS technology enables scalable VPNs and end-to-end QoS over the Internet which requires efficient fault recovery in presence of link or node failures. A major factor on network performance after a failure is the transient congestion that results from restored connections trying to retransmit packets lost since the failure. We focus on the importance of appropriate selection of a rerouting algorithm to control the transient congestion, and we present results from a simulation-based performance study of several routing algorithms. The results show that proper selection of fault recovery routing algorithm can improve MPLS-network performance after a failure.

  This talk considers dynamic fault recovery routing in connection oriented packet switched networks using source node routing. The performance of communication networks immediately after a failure is dominated by a non-stationary traffic load that, in the worst case, can lead to network congestion with severe throughput degradation if not controlled. This talk focus on selecting an appropriate routing algorithm during dynamic fault recovery to control the network performance. A general optimization based formulation of the fault recovery problem is presented and used to model a variety of routing algorithms and fault scenarios. It is discussed how a distributed implementation relates to optimal routing and some results from a simulation based studyare presented. Results show that routing algorithms optimal under steady state conditions are not optimal during failure conditions, and that a dedicated fault recovery routing scheme can improve network performance after failures. The results also show the importance of using representative metrics for measuring the network performance during fault recovery. Finally, some relating issues and some ideas for future work are presented.

  This paper presents a textbook development process for a course in network security in a standard computer science bachelor program. The lack of suitable textbook for the course was coincident with three other needs. One, a change in teaching methods was needed in order to adapt to students with a broad range of skills made necessary by the evolution of universities going from elite- to mass institutions. Second, continuous evaluation of students in a course is required by a new reform of higher education in Norway, and third it is an increased need to document faculty performance. In this paper we present a textbook development process that participate in fulfilling the three needs by using collaborative writing as a tool, and we present some preliminary results from the development of a new course book in network security during the spring semester 2003.

Gitt at det ikke kommer nasjonale bevilgninger for å bygge en ny infrastruktur, og at den økonomiske situasjonen forde fleste kommuner er slik at store investeringer er vanskelig å gjennomføre, må en se på alternative metoder for infrastrukturutbygging slik at en sikrer at kommunene får ta del i den generelle velstandsutviklingen. Det gis tre anbefalinger om hvordanPKI og bredbåndsnett kan implementeres uten store investeringer.

  Information technologies provide opportunities for improved and more flexible working methods in organisations. In particular, the provision of a broadband network infrastructure is an important element in business applications that require the exchange of complex multimedia documents and for integrating many business-to-customer and business-to-business services. The Department of Business and Industry in Møre and Romsdal of Norway proposes that the development of broadband networks could serve to improve the competitive equilibrium between businesses in rural regions and their competitors in more urban regions. This paper presents the findings of a study that investigates the needs of businesses and local governments in this region for subscribingto broadband networks. We address the issues of whether these organisations, feel that they need broadband access, are they currently satisfied with network capacity, and have they future plans for access? Our inquiries separate the issues of business activites from technology requirements. The study asks respondents of their current involvement in e-business activities and in traditional business activities while stating that broadband access is not a prerequisite. Also, we inquire about their future expectations in these areas and in communication opportunities. This study has new and expected findings. The results here in particular focus on the business respondents. Expected findings include a positive interest in broadband networks by the majority of respondents in both rural and urban areas. Revealing feedback was of the types of business activites that were of greatest interest. We also discovered an imbalance in the availability of technological alternatives to rural and urban respondents. This study has lead to a better understanding of the business needs of a region and the importance of broadband network technologies in business strategies.
