Intelligent (knowledge-engineered) computer-aided design emulates the human activity of design so that production planning, decision making and inventional design (creating new designs from sets of given, human-based, design activities) can be performed by computers. With OPTDEX, a cognitive CAD system, concentration is focused on design optimization. Based on the history of human experience in engineering design, a procedural design methodology which includes procedures from (1) conceptual (top level) design, (2) layout (cell level) design and (3) numerical (optimization level) design have been incorporated within OPTDEX. A methodology for planning, and the problems associated with it, within large scale design, are discussed. The generality of our design hypothesis for the design optimization process is examined within the context of a prototypical mechanical design model. An example which demonstrates the applicability of this approach to mechanical power transmission design, and which is representative of a large scale design problem, is given.
