摘　　要：针对传统模糊综合评判方法对定性指标量化较为粗糙、评价过程未考虑系统整体信息的缺陷,给出了利用模糊数对定性指标进行量化的方法;将灰色系统理论引入设计方案的多属性模糊优选,形成基于灰色关联分析的模糊优选模型.该优选模型综合考虑相关因素交叉耦合后的影响,对方案优劣进行整体比较.利用该模型对履带式推土机设计方案进行优选,结果表明新模型可信有效.In view of the shortcomings of traditional fuzzy comprehensive evaluation, which are coarse quantification of qualitative indexes and unconsidering holistic information in the evaluating process, the method of qualitative index's quantification with fuzzy number is proposed. Grey system theory is introduced into the multi-attribute fuzzy optimal selection of design scheme, the fuzzy optimal selection model is formed based on the grey relational analysis. In this model, the influence of crossover and coupling among correlative factors is synthetically considered, and the schemes from the point of view of a holistic are compared. Using the model to select the optimal pedrail bulldozer design scheme, the results show it to be reliable and effective.
