摘　　要：根据设计领域模糊知识的特点 ,提出一种用模糊变量来表示模糊知识的新方法。每个模糊变量包括一系列模糊子集和一个模糊向量 ,这个模糊向量用来描述这一系列模糊子集的隶属函数。在此基础上 ,提出一种模糊推理模型。该知识表示方法采用了统一的范式 ,并且具有很强的灵活性、通用性和易实现性 ,为设计型专家系统工具中模糊知识的处理提供了一种很好的途径。According to fuzzy knowledge characteristics in design field, a new method using fuzzy variable to represent fuzzy knowledge is brought forward in this paper. Every fuzzy variable consists of a series of fuzzy subsets and a fuzzy vector. The fuzzy vector is used to describe these series of fuzzy subset membership function. Based on these, a fuzzy reasoning model is put forward. This knowledge representation method uses uniform pattern and is rather flexible,spread feasible and easy to implement. And it provides a very good approach to deal with fuzzy knowledge in expert system tool applying to design.
