1 KNOWLEDGE INTENSIVE COMPUTER AIDED DESIGN

2 IFIP - The International Federation for Information Processing IFIP was founded in 1960 under the auspices of UNESCO, following the First World Computer Congress held in Paris the previous year. An umbrella organization for societies working in information processing, IFIP's aim is two-fold: to support information processing within its member countries and to encourage technology transfer to developing nations. As its mission statement clearly states, IFIP's mission is to be the leading, truly international, apolitical organization which encourages and assists in the development, exploitation and application of information technology for the benefit of all people. IFIP is a non-profitrnaking organization, run almost solely by 2500 volunteers. It operates through a number oftechnical committees, which organize events and publications. IFIP's events range from an international congress to local seminars, but the most important are: The IFIP World Computer Congress, held every second year; open conferences; working conferences. The flagship event is the IFIP World Computer Congress, at which both invited and contributed papers are presented. Contributed papers are rigorously refereed and the rejection rate is high. As with the Congress, participation in the open conferences is open to all and papers may be invited or submitted. Again, submitted papers are stringently refereed. The working conferences are structured differently. They are usually run by a working group and attendance is small and by invitation only. Their purpose is to create an atmosphere conducive to innovation and development. Refereeing is less rigorous and papers are subjected to extensive group discussion. Publications arising from IFIP events vary. The papers presented at the IFIP World Computer Congress and at open conferences are published as conference proceedings, while the results of the working conferences are often published as collections of selected and edited papers. Any national society whose primary activity is in information may apply to become a full member oflfip, although full membership is restricted to one society per country. Full members are entitled to vote at the annual General Assembly, National societies preferring a less committed involvement may apply for associate or corresponding membership. Associate members enjoy the same benefits as full members, but without voting rights. Corresponding members are not represented in IFIP bodies. Affiliated membership is open to non-national societies, and individual and honorary membership schemes are also offered.

8 Preface Computer Aided Design (CAD) technology plays a key role in today's advanced manufacturing environment. To reduce the time to market, achieve zero defect quality the at first production, and use available production and logistics resources effectively, product and design process knowledge covering the whole product life cycle must be used throughout product design. Once generated, this intensive design knowledge should be made available to later life cycle activities. Due to the increasing concern about global environmental issues and rapidly changing economical situation worldwide, design must exhibit high performance not only in quality and productivity, but also in life cycle issues, including extended producer's liability. This requires designers and engineers to use various kinds of design knowledge intensively during product design and to generate design information for use in later stages of the product life cycle such as production, distribution, operation, maintenance, reclamation, and recycling. Therefore, future CAD systems must incorporate product and design process knowledge, which is not explicitly dealt with in the current systems, in their design tools and design object models. Between 1987 and 1989, the [FIP Working Group 5.2 organized a series of three workshops on "Intelligent CAD," which were followed by a working conference on the same subject in This new series of workshops extends the concept of intelligent CAD to the concept of "knowledge intensive engineering." The concept advocates that intensive life cycle knowledge regarding products and design processes must be

9 x Knowledge Intensive Computer Aided Design incorporated in the center of the CAD architecture. The concept focuses on the systematization and sharing of knowledge across the life cycle stages and organizational boundaries. The first workshop was held at Helsinki University of Technology, Espoo, Finland in September The second workshop was held at Carnegie Mellon University, Pittsburgh, USA, in September The aim of the workshops is to clarify and elaborate the concepts of knowledge intensive design and CAD by providing an international forum for mutual discussions and exchange of opinions of experts of the field. The first workshop focused on exploring the concept of knowledge intensive design as a part of knowledge intensive engineering activities. The second workshop examined architectures and methodologies for "knowledge intensive CAD" based on the results of the first workshop. The third workshop looked at implementations and applications of knowledge intensive CAD systems. The scope of the third workshop included: Ontology Knowledge intensive CAD (KIC) Knowledge intensive design (KID) Knowledge representation for KIC All in all, 17 papers were presented at the workshop, of which 13 were accepted for this volume after a review. The selected papers provide a vivid discussion to encapsulate particular aspects of the central themes. For example, Ontology and Knowledge Representation streams cover some of the fundamental issues associated with these subjects and the KIC and KID streams begin to introduce the applications. We included a keynote speaker paper to discuss the knowledge life cycle and a report about the past, present and future research directions of KIC. Together with the proceeding of the previous workshops, the volume presents an overview of an important novel area of research for researchers, graduate and postgraduate students, system developers of advanced computer-aided design and manufacturing systems, and engineers involved in industrial application of KIC. It discusses not only theoretical aspects but also practical systems and experiences gained from these, and aims to provide a multi-disciplinary view of the subject both from computer science and engineering research angles. The workshop was organized by the IFIP Working Group 5.2 and cosponsored by the following bodies. Japan Society of Precision Engineering.
