Abstract

The problems inherent in expert systems which model human design processes are discussed. An example of such a system is given with PLEX, a knowledge-based expert system that does initial placement of components on a printed circuit board. A discussion follows on how dependency-directed backtracking and human-aided machine design are being added to PLEX to help overcome some of the difficulties in modeling a human designer.
