AEX: a DFA analysis and advisor system

Abstract
The concept of designing products for low cost and easy assembly operations is explained. The general system architecture and methodology of assembly expert (AEX), knowledge-based software under development that will assist the designer optimize product design with respect to low cost and easy assembly, are described. AEX is intended as a subsystem of a general CAD system, rather than a substitute for it. Results for the prototype system and the current status of the full-scale development of AEX are reported. The prototype shows that AEX is cleanly hierarchical and easily expandable, due to the hierarchical nature of the GT code part representation used.<>
