USES OF ARTIFICIAL-INTELLIGENCE IN DESIGN OPTIMIZATION

In this paper, basic ideas and concepts of using artificial intelligence in design optimization of engineering systems are presented. The purpose of the study is to develop an expert (knowledge-based) system that helps the user in design optimization. Two basic ideas are advocated: (1) the successful numerical implementation of algorithms needs heuristics; and (2) the optimal design process can be greatly benefited by the use of heuristics based on knowledge captured during the iterative process. Various steps in the optimization process, where artificial intelligence ideas can be of tremendous help, are delineated. Some simple rules are presented to utilize the knowledge base and raw data as it accumulates in the iterative process. A simple example is used to demonstrate some of the basic ideas.
