摘要
通过改进证据相似度提出一种新颖的证据合成规则方法,有效解决了存在冲突证据时的证据理论(Dempster-Shafer,D-S)合成悖论问题。引入相容系数构造参考证据体,运用加权平均证据作为参考证据体;借助相似三角函数,判定异常证据体;运用D-S合成进行证据合成方法对各个证据进行融合。仿真结果表明,所提出的方法能够有效处理冲突证据,相对于其他几种典型改进算法具有更快的识别速度和精度。
A novel evidence synthesis rule method is proposed by improving the similarity of evidence,which effectively solves the Dempster-Shafer(D-S)synthesis paradox in the presence of conflicting evidences.The reference body is constructed by using compatibility coefficient,and weighted average evidence is used as reference body.Abnormal evidence body is determined by using similar trigonometric function.The D-S synthesis method is used to integrate all the evidences.The simulation results show that the proposed method can effectively deal with conflicting evidences,and has faster recognition speed and better accuracy than other typical improved algorithms.
