基于遗传算法的产品造型设计阶梯求解法

A Ladder-type Method Based Genetic Algorithm for Product Shape Design

基于参数化产品设计的造型编码,采用产品目标用户参与的方式评定造型参数的权重;根据权重次序将产品设计的造型编码进行阶梯分级;通过阶梯降级的方式对原始解空间进行数据处理,每次降级利用交互式遗传算法搜索产品造型设计的最优解,逐级完成造型设计的细化设计。求解过程基于解码的造型方案进行,并为设计师提供了直观的操作界面。

Based on the parameterized coding of product shape,the method that lets customers participate the process is used to evaluate parameters’ weights.According to the order of the parameters’ weights,the shape coding of product design is sorted.The data is processed by the ways that degrade the ladders,and the seeking optimal is searched through interactive genetic algorithm.Then the product shape detail is determined gradually.The solving process is thoroughly based on decoded product shapes,which provides designers the visualized interface.
