PROLAMAT 2001

IFIP 11th  PROLAMAT 2001 Conference on Digital Enterprise – New Challanges.

The information technology revolution of the 1980s and 1990s made a strong impact on production technology as well as on its management, and many of today’s enterprises can rightly be called digital enterprises. The pervasiveness of computers and networks has enabled the full computerization of production, and further on the whole supply chain. Decision support systems and other management support tools have also become more and more widespread. As the web of computer networks gradually expanded, it opened up the possibility of global, computer assisted production, management, etc. Different stages of the design and production process can now be conducted at different parts of the globe, and still be overseen by real-time control and management. Networked activities are not restricted to one enterprise: virtual enterprises allying different companies for the lifetime of a project are heavily relying on computer-enabled communication, cooperation and coordination, and business-to-business (B2B) commercial activities via electronic communication are becoming everyday practice. The computing power of today’s equipment has reduced the calculation time of modeling and simulation to such an extent that new approaches using computation intensive methods, techniques and algorithms have become feasible to employ. Using modeling and simulation tools a wide range of alternatives can be examined quickly to provide support for decisions. Design and manufacturing time has also been reduced, which allows faster response to market needs. The 2001 PROLAMAT focused on one of the greatest new challenges facing these digital enterprises: Life Cycle Approach in Management and Production. In an increasingly environment conscious world manufacturing and production is regarded as part of a larger picture: the product life cycle (production – use – disposal). This approach is characterized by three aspects: technology, economy and ecology (environmental impact). The PROLAMAT conference focused on technology but also included papers on the other two aspects; various solutions for the different activities are described in the papers. While elements of integrating several phases of the product life cycle have been apparent in earlier approaches, such as Design for Manufacturing, Design for Maintenance etc., the life cycle approach looks at the different phases from a holistic aspect. Modeling can help in calculating the cost of a product, both in the manufacturing stage and in later stages of the product’s life. As cost can be a decisive factor in a product’s success, support tools can be used to facilitate the examination of economy aspects. Other uses of modeling include analysis and simplification of complexities in the supply chain that includes life cycle dependencies. Using the life-cycle approach a product model can be reverse engineered from the intended use and the given set of constraints, and the optimum design is derived from the desired outcome. The principal message of the conference was that engineering has to embrace the whole life-cycle of the product, which includes environmental, social and economic sustainability of the production – supply chain, customer use and disposition phases. Life cycle thinking integrates many different processes to give a complete view; from product design to decommissioning and disposal.
