多色集合的研究及在机械产品概念设计中应用

Study of Polychromatic Sets and Its Application in the Concept Design for Mechanical Products

在多色集合这一信息处理工具的基础上 ,建立了面向离散系统建模与分析的多色集合模糊数学模型 ,给出按多色集合模糊数学模型进行设计的准则和机械产品概念设计的搜索算法 .使用该搜索算法可以得到符合技术规范的若干可行产品方案 ,组成可行产品方案集 ;然后利用方案选择算法 ,可以在确定的可行产品方案集中选择出合理的产品方案 ;

Fuzzy mathematics m odel built up on the basis of polychromatic sets is developed to modeling and analyzing the discrete system.Design rules and search algorithm are worked out for conceptual design of m echanical products.The search algorithm is able to find out several feasible schem es of product design conforming to the established technical specifications,resulting in a set of candidate solutions.Evaluation functions are applied to choose the m ost reasonable one.An example of m achining center layout is presented to illustrate the feasibility of new approach.
