基于层次分析法的二级模糊综合评判在机构选型中的应用

Application of AHP based on two-level fuzzy synthesis judgments in mechanism selection

在概念设计阶段中，机构的选择与评价较为重要．提出基于层次分析法的二级模糊综合评判方法，采用模糊统计实验法确定隶属度，采用层次分析法中的1～9标度法确定权重．该方法将定性分析与定量分析相结合，把数学处理和人的经验与主观判断相结合，把人的主观因素限制在较小的范围内，保证了评价结果的准确性．

In concept design phase, selection and evaluation of mechanism are crucial. Two-level fuzzy synthesis judgments method based on hierarchical analysis method is proposed, which adopts fuzzy statistical cut-and-try method to determine degree of membership and utilizes 1-9 scale law in analytic hierarchy process （AHP） to decide weights. This method combines qualitative analysis with quantitative one, and integrates personal experience and judgments with mathematical operation, which circumscribes person＇s subjective factor into minimum range to guarantee the correctness of evaluation result.
