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.
This text aims to extend the concept of intelligent CAD (computer-aided design) to the concept of "knowledge intensive engineering". The concept advocates that intensive life-cycle knowledge regarding products and design processes must be incorporated in the centre of the CAD architecture. It focuses on the systemization and sharing of knowledge across the life-cycle stages and organizational boundaries. The fields covered in this text include: computer-aided design and manufacture (CAD/CAM), engineering design research, artificial intelligence and knowledge-based systems, computer science, particularly distributed systems, and software engineering.
