摘　　要：针对机床设备的最优选择问题,提出一种结合模糊层次分析(FAHP)法与模糊复杂比例评价(COPRAS)法的优选方法.首先,基于生产需求和专家知识确定机床性能的主要属性和候选机床方案.然后,根据以三角模糊数表示的专家判定,构建各属性间的模糊比较矩阵,并利用FAHP方法获得各属性的重要性权重.接着,构建各属性与备选方案之间模糊决策矩阵,并将其与属性权重相乘获得加权归一化决策矩阵.最后,利用模糊COPRAS方法对决策矩阵进行分析,获得各备选方案的效用度,从而选择出最优备选方案.以铣削机床优选为案例进行分析,结果表明该方法具有可行性和有效性.For the issue that the optimal selection of machine tool equipment,a method combining fuzzy analytic hierarchy process（FAHP）with fuzzy complex proportional assessment（COPRAS）is proposed.Firstly,the main properties of the machine tool performance and candidate machines are determined based on the production requirements and expert knowledge.Then,the fuzzy comparison matrix of each attribute is constructed according to the expert judgment represented by triangular fuzzy number,and the FAHP method is used to obtain the importance weight of each attribute.After that,the fuzzy decision matrix between attributes with alternatives is constructed,and multiplying it with the attribute weight so as to obtain the weighted normalized decision matrix.Finally,the fuzzy COPRAS method is used to analyze the decision matrix to get the utility of each alternative.The results show that the method is feasible and effective in the case of milling machine tool selection.
