中文摘要：

针对经典DS证据理论在处理高度冲突的证据信息时会产生有悖常理结论的情况，基于证据支持度的思想，引入了证据之间相容系数的概念，并随之引入证据可信度的概念，提出了一种新的证据权重的确定方法；最后运用DS证据理论组合规则进行数据融合。与之前其他处理方法相比，考虑到证据之间冲突与包容共存的情况，客观计算证据的权值，收敛更快，融合结论更符合事实，弥补了经典证据理论的不足，为DS证据理论的改进提供了一条新的途径。

英文摘要：

Aiming at there will generate a counter-intuitive conclusion when classical DS evidence theory handle the highly conflict evidence information, this paper introduced the concept of compatibility ratio between conflict evidences based on the evidence support degree, and the concept of evidence credibility ratio, presented a new determine method for evidence weight, using DS evidence theory combination rules for data processing at last. Compared with other existed methods, this paper consid- ered the conflict and consistency, calculated the evidence weight objectively, it was faster in data convergence, the conclusion was more consistent with facts. It made up the deficiency of DS theory and provided a new way for DS evidence theory algorithm improving.
