Dempster-Shafer combination results may be not in agreement with the real condition when the evidences are highly conflict;and this problem has been widely investigated by some improved methods. However, those methods are not as good as Dempster-Shafer combination rule when the evidences are consistent. Therefore, a novel evidence combination method is proposed in this paper based on evidence credibility. First, the mean square Euclidian distance between evidence and evidence subset is obtained after establishing the evidence distance matrix, and the credible factor Εis calculated to modify the evidence resource correspondingly by a confidence function, and then these modified evidences are combined together according to the D-S rule. Simulation experiments demonstrate the effectiveness of this new improved algorithm when dealing with conflicting evidences and consistent ones.
