変動多数決ルールを用いたCA法による構造最適化の研究

抄録

The structural optimization problems consist of phase optimization and size optimization steps. The size optimization is comparatively easily using a mathematical technique, but the more important phase optimization is difficult. Until now, researches using GA, NN, SA and CA as the phase optimization technique are done. In this paper, “the method by CA changing majority rule” is proposed. It is the method searching an optimal structure without increasing a design variable and keeping design space large. Moreover this method makes the operation from phase determination to size decision systematically. By using the method, the design problems of the optimum board thickness distribution are analyzed as an exercise about the validity
