中文摘要：

针对具有置信度信息的多属性匹配决策问题，提出了一种决策方法．给出了等级置信度的概念及其相关证明，将双边的多种形式置信度评价信息转换成等级置信度信息．在此基础上，把等级置信度信息作为证据，通过融合证据计算双边匹配融合度，并求解基于融合度的优化模型来获得匹配结果．最后，通过算例验证了该方法的可行性和有效性．

英文摘要：

A decision-making method is proposed to solve the multi-arrtibute matching decision-making prob- lem with belief degrees. First, the description of rank belief degrees is given and related theoretical proofs are presented. Then, belief degrees with multiple format data are transformed into rank belief degrees. On this ba- sis, rank belief degrees are taken as pieces of evidence and fusion degrees of two-sided matching are computed by using evidence fusion. Furthermore, a two-sided matching alternative is obtained by solving optimization model based on fusion degrees. Finally, a numerical example shows the feasibility and validity of the proposed approach.
