基于幂Pignistic概率距离的加权证据组合方法
Weighted evidence combination method based on power-Pignistic probability distance
摘要
Abstract
To deal with the shortcomings encountered when using the existing similarity/dissimilarity measures to quantify evidence conflict,a new dissimilarity measure called power-Pignistic probability distance was defined.Furthermore,a weighted evidence combination method was proposed based on power-Pignistic probability distance.The conflict degree between two pieces of evidence was quantified by the power-Pignistic probability distance.After that,a similarity measure matrix was constructed,based on which the credibility of evidence was obtained.Then the weighted average method was used to revise the evidence.Finally,the fusion was accomplished by using Dempster's rule.The results of the numerical examples show the efficiency and rationality of the proposed method.关键词
