摘要
首先讨论了冲突信息利用的几种途径 ,在此基础上提出了一种新的证据合成法则 ,将焦元的基数及信度的相对差异引入到新合成法则中 ,并在焦元及焦元的两两并集上分配信度 ,从而更合理地表达不确定和保留冲突信息 ;并且不用针对特殊情况进行处理 ,体现了新合成法则在形式上的统一性 .
This paper discusses several ways to utilize conflicting evidences, and on the basis of them, it presents a new combination rules. dimension of focus element and the belief difference of two belief functions are suggested into the new combination rules; for all of focus element A i,B j, A i, B j and A i∪B j are all provided some BPA, which can express uncertainty and keep conflict more properly; and more the new combination rules avoid special treatment in special cases, which show uniformity formally of the new combination rules.Typical evidences and real instances show this combination rules can combine highly conflicting evidences more satisfactory.
