Proceedings (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- 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.

- Product-mix flexibility is one of the major types of manufacturing flexibility, referring to the ability to produce a broad range of products or variants with presumed low changeover costs. The value of such a capability is important to establish for an industrial firm in order to ensure that the flexibility provided will be at the right level and used profitably rather than in excess of market requirements and consequently costly. We use option-pricing theory to analyse the impact of various product-mix issues on the value of flexibility. The real options model we use incorporates multiple products, capacity constraints as well as set-up costs. The issues treated here include the number of products, demand variability, correlation between products, and the relative demand distribution within the product mix. Thus, we are interested in the nature of the input data to analyse its effect on the value of flexibility. We also check the impact at different capacity levels. The results suggest that the value of flexibility (i) increases with an increasing number of products, (ii) decreases with increasing volatility of product demand, (iii) decreases the more positively correlated the demand is, and (iv) reduces for marginal capacity with increasing levels of capacity. Of these, the impact of positively correlated demand seems to be a major issue. However, the joint impact of the number of products and demand correlation showed some non-intuitive results. ⌐ 2002 Elsevier Science Ltd. All rights reserved.

Tidskriftsartikel (refereegranskat)abstract
- Flexibility in manufacturing operations is becoming increasingly more important to industrial firms, due to e.g., increasing market demand volatility, internationalisation of markets and competition, and shorter product life cycles. Defining, measuring and evaluating manufacturing flexibility have not been straightforward - neither in theory nor in practice. The use of real options has shown to be an accessible approach for the valuation of certain types of flexibility. When using real options for capital budgeting purposes it is possible to take flexibility options into account in the valuation process. In this paper, we use real options to evaluate one specific type of manufacturing flexibility, i.e., product-mix flexibility. We provide both theoretical and practical perspectives, based on a real case. The main interest of the company under study is to evaluate product-mix flexibility with respect to capacity, set-ups, level of automation and multi-functionality of resources. The case involves multiple products and demand uncertainty, wherefore product demands are used as the underlying asset in the real options models. Thus, the contribution of this paper concerns the combination of real case, multiple products, capacity constraints, and set-up costs. The results of the analysis show that (i) the value of flexibility decreases when demand volatility increases, (ii) flexible resources add substantial value as compared to dedicated resources, and (iii) the flexibility value of marginal capacity decreases with increasing levels of capacity.

- 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

- The purpose of the paper is to explore the way manufacturing firms use internal and external suppliers in the design and management of manufacturing networks. The main area of interest is to explore the similarities and differences between internal and external suppliers, with respect to their roles and the reasons for choosing a certaintype of supplier. We base our analysis on data from 104 Swedish manufacturing plants and their corresponding manufacturing networks of internal and external suppliers. The results of the study show that there are significant differences between the criteria that are influential in choosing a certain type of supplier. The choice of an internal supplier is largely based on a single corporate decision, while an external supplier has to perform well on a number of criteria (primarily quality, cost, and delivery dependability). When comparing the selection criteria withcompetitive priorities and plant performance, we find that the criteria for selecting external suppliers has a better match than those for selecting internal suppliers. The sample contained plants having only external suppliers as well as plants having both internal and external suppliers,but the selection criteria for external suppliers are the same for both groups and not dependent upon the presence or absence of internal suppliers.
