基于信度优势的比例冲突再分配规则

比例冲突再分配规则是高冲突证据合成的一种有效方法,但其处理思想保守,没有充分利用证据的信度。为此,提出了基于信度优势的改进规则,通过构造信度函数,并作为权重对原始分配比例进行加权,增大两信度之间的比值,提高优势命题的权重,使证据的信度优势得到了明显体现。算例分析验证了该规则的有效性。

Proportional Conflict Redistribution Rules Based on Preponderant Belief

Although the proportional conflict redistribution rule is an effective method of high conflict evidence combination,its processing idea is conservative for exploiting the belief of evidence insufficiently.Therefore,an improved rule based on preponderant belief is proposed.A novel belief function weighted for the initial distributed proportion is constructed.Thus,the ratio of two belief is increased,and the weighting of the dominant proposition is enhanced,which obviously represents the preponderant belief o...
