Design methodology in knowledge-based design systems

Knowledge-based systems, reinforced through research and development, are penetrating industrial areas of application. Meanwhile they have successfully proven their practical applicability for certain fields of operation. To enlarge the computer support in the design area, it is necessary to develop a CAD methodology, which makes the work with CAD systems more effective. Computer supported knowledge processing opens a new class of solutions for design which did not seem to be achievable with the conventional systems available up to now.
