The combination method of local conflict evidence based on credibility of focal element

摘要

Though the D-S evidence theory has been widely used in information fusion, when the evidence is in high-conflict, but the results of D-S combination rule may be wrong. As to solve this problem, this paper proposes a combination method of local conflicts evidence based on credibility of focal element. First, get the trust degree and average evidence based on Jousselme theory. And then obtain the absolute distance from seeking distance. Finally, we can obtain the trust degree of focal element. The experimental results show that the proposed algorithm can improve the efficiency and rationality of evidence synthesis results.
