机械系统概念设计的机构选型模糊综合评价

把层次分析法（ＡＨＰ）与二级模糊综合评价法相结合，进行机构选型的评价与决策。其过程包括：确定备选 机构的评价准则及综合评价指标体系、二级模糊综合评价模型及评价方法、机械产品原理方案中备选机构的排序、 确定各评价目标所占的权重，最终选定执行机构。

Fuzzy Synthetical Evaluation for Selecting Mechanism Types on Conceptual Design of Mechanical System

We combine the Analytic Hierarchy Process (AHP)and the Fuzzy Synthetical Evaluation Method to evaluate mechanisms, which are selected. The new process consists of several steps: confirm an evaluation objectives and a synthetical evaluation index system of the mechanisms; a fuzzy synthetical evaluation model and a method of the mechanisms are proposed; put the synthetical score of the mechanisms in order; calculate the weights of evaluation objectives; we make a mechanism ac-cording to the synthetical score. Finally, a practical example is given.
