中文摘要：

针对产品方案评价体系中评价指标的权重分配及指标间关联关系的分析问题,提出了一种基于模糊层次分析法（AHP）和模糊决策试行与评价实验方法（DEMATEL）的混合模型。模糊AHP通过对评价粒度和评价指标的两两重要性对比建立二级判断矩阵,然后经过一系列运算确定评价指标的权重精确值。模糊DEMATEL对评价指标间的相互影响关系进行定量分析,同时结合AHP法得到的权重值获得各评价指标的赋权中心度和原因度,并据此构建影响关联图。实例分析表明,所提的理论和方法在工程应用中是可行、有效的。

英文摘要：

To obtain weights of evaluation criteria and analyze the relationship between the criteria in product scheme evaluation system, a hybrid model is proposed based on fuzzy analytic hierarchy process （AHP） and fuzzy Decision Making Trial Evaluation Laboratory （DEMATEL）. Two judgment matrix composed of pair-wise comparison among evaluation dimension and evaluation criteria is built in Fuzzy AHP, and crisp values of evaluation criterion weights are obtained after computation. The weighted degrees of prominence and relation in fuzzy DEMATEL are obtained by quantitative analysis of influential relationship among evaluation criteria , based on which the influence relation map is made. An example is executed and analyzed, which verifies the feasibility and effectiveness of the proposed theory and method in engineering applications.
