摘　　要：从产品结构设计入手,论述了面向装配的机械产品结构设计通用评价指标体系以及针对具体产品的专用评价指标体系的建立方法,探索了产品结构设计的模糊评价方法和步骤,论述了面向装配的机械产品结构设计模糊评价的实现技术。其中包括框架和规则相结合的知识表达形式、利用Matlab建立评价指标知识获取平台的方法、推理确定隶属度函数的方法以及采用德尔菲法确定指标权数的步骤等,并针对具体机械产品进行了评价和分析。Starting with the product structure design mechanical product structure design for assembly , the general evaluation index system of and the special evaluation index system for concrete product have been set up, meanwhile the fuzzy evaluation methods and procedure for product structure design were explored. Some techniques related with fuzzy evaluation of mechanical product structure design for assembly have been carried out, and knowledge representing form of combining frame with rule, establishing method of acquiring knowledge platform for evaluation-index by using Matlab, membership function determination method through reasoning, adopting the Delphi method for determining the steps of index weighing were all included in the techniques. Further more, a specific mechanical product was assessed and analyzed.
