Application of Genetic Algorithm in Hierarchical Structure Product Integer Conceptual Innovation Design
一种基于知识进化的多层次结构产品整体方案创新设计方法*

Based on the genetic algorithm, a model of hierarchical structure product integer conceptual innovation design system is researched and proposed. In this paper, particular emphasis is placed on the fact that machine systems generally have hierarchical structures. Via treating those machines conceptual designs as design spaces to resolve, using the genetic algorithm, controlled its search process on the whole, a new hierarchical genotype representation is developed. In order to adapt this kind of representation, the genetic operators include of crossover operators and mutation operators, i.e., are newly constructed. Utilized the reproduction, crossover and mutation i.e. to iteration, a set of optimized design scheme are built automatically. A design example demonstrates this system is effective, exact and applied.
