摘要

针对D-S证据理论在处理高度冲突证据时存在的不足

提出了一种新的基于证据预处理的组合方法。该方法根据各证据体与其余证据的冲突程度定义各证据体的可信度

利用证据体的可信度和原证据集中命题的支持度对原证据集进行预处理

然后对处理后的证据集采用D-S组合规则进行合成。此方法不仅有效地避免了在冲突证据合成时出现有悖常理的现象

又保留了经典D-S合成规则优越的信息聚焦性能。通过算例验证了新方法合成结果的可靠性与有效性。

Abstract

In view of the deficiency of D-S evidence theory in combining highly conflictive evidence

a new combination rule based on evidence preprocessing is presented.In the improved method

evidences are preprocessed according to their reliable degree and the supported degree of every proposition.The unreasonable combination results when evidences conflict with each other is avoided and the superiority of information focusing like a classical D-S rule is reserved by the improved method.The reliability and effectiveness of the new combination rule are proved by an example.
