Knowledge-Intensive CAD clarifies and elaborates the concepts of knowledge-intensive design and CAD. In today''s advanced manufacturing environment, CAD systems should not only assist designers and engineers during product design, but also in design information for use in later stages of the process such as production, distribution and operation. This book focuses on the sharing of knowledge across life-cycle stages and organizational boundaries.

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 first time, 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. These goals require 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 are not explicitly dealt with in the current systems, in their design tools and design object models.

Computer aided design (CAD) technology plays a key role in advanced manufacturing environment. This work extends the concept of intelligent CAD to knowledge intensive CAD. The concept advocates that intensive life-cycle knowledge regarding products and design processes must be incorporated into the centre of the CAD architecture. Knowledge intensive CAD focuses on the systematization and sharing of knowledge across the life-cycle stages and organizational boundaries.

This work is based on the premise that life-cycle knowledge regarding the product and design process must be incorporated in the centre of CAD architecture. It focuses on the systematization and sharing of knowledge of many types in many places and is concerned with knowledge management over product life-cycle. The topics covered here include: ontology; knowledge-intensive CAD (KIC); knowledge-intensive design (KID); and knowledge representation for KIC. The papers represent some of the proceedings of the Third Workshop on Knowledge Intensive CAD, sponsored by Working Group 5.2 of the International Federation for Information Processing (IFIP) and held on December 1--4, 1998 in Tokyo, Japan.

CAD (Computer Aided Design) technology is now crucial for every division of modern industry, from a viewpoint of higher productivity and better products. As technologies advance, the amount of information and knowledge that engineers have to deal with is constantly increasing. This results in seeking more advanced computer technology to achieve higher functionalities, flexibility, and efficient performance of the CAD systems. Knowledge engineering, or more broadly artificial intelligence, is considered a primary candidate technology to build a new generation of CAD systems. Since design is a very intellectual human activity, this approach seems to make sense. The ideas of intelligent CAD systems (ICAD) are now increasingly discussed everywhere. We can observe many conferences and workshops reporting a number of research efforts on this particular subject. Researchers are coming from computer science, artificial intelligence, mechanical engineering, electronic engineering, civil engineering, architectural science, control engineering, etc. But, still we cannot see the direction of this concept, or at least, there is no widely accepted concept of ICAD. What can designers expect from these future generation CAD systems? In which direction must developers proceed? The situation is somewhat confusing.
