摘要
Pignistic probability distance can describe evidence distance accurately. The paper calculates the similarity of evidence based on Pignistic probability distance, then determines the relative weight of evidence. In the Dempster’s combination rule, every piece of evidence has equal importance, which severely limits the application of evidence theory, thus we revise the combination rule by introducing the weight into it. The system simulation shows that the revised combination rule reaches better result which in accordance with basic human cognition.
