Considering Dempster combination rule's disadvantage in efficiently combining the conflict evidence,this paper presented the improved definition of evidence conflict and computation equation of evidence conflict degree based on conflict coefficient and Jousselme distance and established a new evidence combination method based on evidence conflict degree.This method firstly constructed an evidence support degree matrix.Then computed the evidence weight vector.Finally,used Dempster combination rule to combine the evidence modified by weight vector.A numerical example illustrates the efficiency of the proposed method in combining the conflict evidence.Compared with Dempster combination rule and several typical weighting methods,the proposed method is more efficient.
