KNOWLEDGE-BASED SYSTEMS FOR DESIGN

knowledge-based systems are a special class of computer programs that purport to pet-form, or to assist humans in performing, specified inte llectual tasks. This paper describes how knowledge-based programs are special; that is, how they differ from other computer programs. A stru cture for understanding the use of knowledge-based programs in enginee ring design is presented, together with an example. The role of knowle dge-based systems in design research is discussed.
