一种处理冲突证据的合成方法

证据推理广泛应用于不确定推理和数据融合等方面。但D-S合成规则对于高冲突情况的处理不是十分合理的。因此文中提出了一种基于证据相似系数的冲突证据合成方法。此方法首先引入了相似系数的概念。然后求出各证据被其它证据所支持的程度，对支持度归一化后可得到各证据的可信度，并将可信度作为证据的权重。对证据加权平均后再利用D-S合成规则。

A Kind of Evidence Combination Rule in Conflict

The evidence reasoning widely applies in indefinite inference and data fusion aspect, but the D-S combination rule regarding high conflict situation processing is not extremely reasonable. So this article proposed one kind of conflict evidence combination rule based on the similarity, This method has first introduced the concept of similarity sign, and then extracts various evidence the degree which is supported by other evidence, may obtain various evidence confidence level after the support normalization, and the confidence level took the evidence the weight, uses the D-S combination rule again after the evidence weighted average.
