为解决高冲突证据下的D-S证据理论失效这一问题,在对已有一些代表性改进方法分析的基础上,提出了一种新的基于最优权重分配的D-S改进算法.在保证证据冲突整体最小情况下,建立证据最优权重分配模型,对原证据模型进行修正.通过实例分析,并与其它改进方法进行对比,验证了该算法在解决冲突证据方面更为有效.
In order to solve the problem of failure of DS evidence theory under the evidence of high conflict, a new improved DS algorithm based on optimal weight assignment is proposed based on the analysis of some existing representative methods of improvement. In the smallest case, the optimal evidence weight distribution model is established and the original evidence model is modified, and by comparing with other improved methods, it is verified that the algorithm is more effective in resolving conflict evidence.
