- The IFIP series publishes state-of-the-art results in the sciences and technologies of information and communication. The scope of the series includes: foundations of computer science; software theory and practice; education; computer applications in technology; communication systems; systems modeling and optimization; information systems; computers and society; computer systems technology; security and protection in information processing systems; artificial intelligence; and human-computer interaction. Proceedings and post-proceedings of referred international conferences in computer science and interdisciplinary fields are featured. These results often precede journal publication and represent the most current research. The principal aim of the IFIP series is to encourage education and the dissemination and exchange of information about all aspects of computing.

- The design and management of the manufacturing network for a firm is an important factor for its competitive position. By manufacturing network we mean the plant or plants of a manufacturing firm and the relationships with external suppliers. The way that these operate together is crucial for supporting the competition of the products in the marketplace. This article presents the results of a survey of 106 Swedish manufacturing plants. We find that the markets and supply networks of Swedish plants are global, but there is a focus on Europe. The main reason for locating a plant in Sweden is proximity to skills and knowledge, and we find no pure low-cost plants. The overall level of site competence is very high. There are many significant differences between how internal and external suppliers are selected. The choice of internal suppliers, i.e. those suppliers in the manufacturing network that belong to the same firm, is to a large extent based on a single corporate decision reflecting quality and competence, while external suppliers are chosen based on quality, price and delivery dependability considerations. This study provides a broad analysis of the manufacturing networks in which Swedish plants operate, and the roles of these plants.

- The design of the manufacturing network for a firm is an important factor for its competitive position. By manufacturing network we mean the plant or plants of the manufacturing firm and the relationships with external suppliers. The way that these operate together is central to the entire supply system supports the competition of the products in the marketplace. The decisions are typically categorised as related to facilities and vertical integration, two decision categories in an operations strategy. This paper presents the results of a survey of 84 Swedish manufacturing plants. The results show that competitive priorities such as quality and price play different roles in the networks, and that there is a significant difference in terms of how internal and external suppliers are selected

- Purpose: To evaluate the accuracy of articular cartilage thickness measurement when implementing a new technology based on spectroscopic measurement into an arthroscopic camera. Methods: Cartilage thickness was studied by ex vivo arthroscopy at a number of sites (N = 113) in human knee joint osteoarthritic femoral condyles and tibial plateaus, removed from 7 patients undergoing total knee replacement. The arthroscopic image spectral data at each site were used to estimate cartilage thickness. Arthroscopically derived thickness values were compared with reference cartilage thickness as measured by 3 different methods: needle penetration, spiral computed tomography scanning, and geometric measurement after sample slicing. Results: The lowest mean error (0.28 to 0.30 mm) in the regression between arthroscopic and reference cartilage thickness was seen for reference cartilage thickness less than 1.5 mm. Corresponding values for cartilage thickness less than 2.0 and 2.5 mm were 0.32 to 0.40 mm and 0.37 to 0.47 mm, respectively. Cartilage thickness images-created by pixel-by-pixel regression model calculations applied to the arthroscopic images-were derived to demonstrate the clinical use of a camera implementation. Conclusions: On the basis of this investigation on osteoarthritic material, when one is implementing the spectroscopic method for estimating cartilage thickness into an arthroscopic camera, errors in the range of 0.28 to 0.30 mm are expected. This implementation does not, however, influence the fact that the spectral method performs less well in the cartilage thickness region from 1.5 to 2.5 mm and cannot assess cartilage thicker than 2.5 mm. Clinical Relevance: Imaging cartilage thickness directly in the arthroscopic camera video stream could serve as an interesting image tool for in vivo cartilage quality assessment, in connection with cartilage diagnosis, repair, and follow-up.

Simulating production and inventory control systems : a learning approach to operational excellence

Tidskriftsartikel (refereegranskat)abstract
- The search for operational excellence includes both a thorough understanding of the nature of the manufacturing operations and a choice of the right production and inventory control system for the environment in which it will operate. Understanding the nature of manufacturing operations can be facilitated by simulating the manufacturing system, so that the interrelationships among parameters can be studied. Production and inventory control systems can be simulated together with the physical manufacturing environment in order to enhance the understanding of the behaviour of a particular control system and also to facilitate the selection of control systems for the manufacturing system under study. In this paper we report on the design and learning effects of using simulation for investigating the behaviour and impact of different production and inventory control systems in a manufacturing system. We discuss the structure and simulation perspectives of production and inventory control systems. We provide a review of the benefits of using simulation for learning the manufacturing environment, and the related testing of alternative control systems.

Tidskriftsartikel (refereegranskat)abstract
- This paper deals with the impact of supply chains on operations management at Ericsson Mobile Communications. It specifically deals with the transition of the Link÷ping plant from being a production unit to the role of a supply unit in a demand-driven supply chain. This change has had a great impact on many factors. We discuss and analyse the most important issues. These are related to supply chain structure and flexibility, reengineering the information flow, the management of the supply process, and performance measurement.
