一种新的冲突衡量方式

New Method of Conflict Measurement

冲突证据的合成问题一直是学者们的关注重点,解决冲突证据的合成问题首先要解决的就是证据冲突程度的衡量,判断证据间有无存在冲突,冲突程度有多大。但是目前对冲突证据中的"冲突"缺乏一个很好的衡量标准。针对这个难题,分析了D-S证据理论中冲突系数存在的不足,介绍了几种常用的冲突衡量方式,并提出了一种基于Pignistic转换的冲突衡量方式,最后通过算例验证,与其他方法进行对比表明这种方法的有效性。

The problem of the combination of conflict evidence has been the focus of attention of scholars.To solve the problem of the combination of conflict evidence,the first thing to be solved is to measure the degree of conflict evidence,and judge whether there is a conflict between evidence and how big the degree is.But there is a lack of a measure of conflict.Aiming at this problem,this paper analyzes the insufficiency of conflict coefficient in D-S evidence theory,introduces several common conflict measurement methods,and puts forward a kind of conflict measurement method based on Pignistic probabilistic transform.Finally,the validity of this method is verified by numerical examples and compared with other methods.The proposed method is robust and more efficient.
