D-S（Dempster-Shafer）证据理论能够有效地处理不确定信息，在信息融合领域得到了广泛的应用。针对 D-S 证据理论在处理高冲突证据时存在的不足，提出了一种新的证据组合方法和量化的评价指标。所提方法利用相容系数来确定每个证据关于各个命题的权重，对证据源进行修正后再利用 D-S 证据理论组合规则进行融合。评价指标则是利用证据源的权重对合成结果与原始证据之间的冲突进行加权求和。仿真实验结果表明，同已有方法相比，所提方法的合成结果更加合理。相应的评价准则也符合主观认识，显示出良好的评价性能。

Dempster-Shafer (D-S)evidence theory can effectively deal with the dubious information and has been widely used in the field of information fusion.Because of the shortcomings of D-S evidence theory in com-bining highly conflict evidences,a novel combination method and a quantitative evaluation index are proposed. The proposed method uses the weight of each proposition in the evidences,which is generated based on the com-patibility ratios to modify the original evidences,and then the D-S rule is applied to the evidence combination. The evaluation index is obtained by averaging the conflicts between the combination results and the evidences ac-cording to the weights of the orighinal evidences.Simulation experiments show that the results of the proposed method are more rational than other existing methods.Also the proposed evaluation rule is in accord with the subjective understanding and performs well.
