一种有效处理冲突证据的组合方法

EFFICIENT COMBINATION APPROACH OF CONFLICT EVIDENCE

为了有效融合高度冲突的证据 ,提出一种新的基于证据距离的组合方法 .首先引入了一个证据体距离函数 ,之后求出系统中各证据被其它证据所支持的程度 ,对支持度归一化后获得各个证据的可信度 ,并将可信度作为证据的权重 ,对系统中的证据加权平均后再利用Dempster组合规则实现信息融合 .与其它方法比较 ,该方法在系统存在伪证据 (干扰 )

In order to efficiently combine highly conflict evidence, a new method based on the distance of the bodies of evidence was proposed. First, a distance function between the bodies of evidence was introduced. Then, the support degree and the credibility of each evidence were obtained. Finally, weighted averaging the evidence in the system, the Dempster combination rule was used to realize information fusion. Comparing with the existing methods, the proposed approach is more efficient in combining conflict evidence.
