传统的证据理论由于自身的缺陷,面对高冲突下的证据组合无法正常融合,或者融合结果不理想。针对这个问题,提出一种修正的证据理论,运用模糊测度和置信距离相结合的方法产生新的权重,对冲突证据体进行加权和修正,从而获得较为理想的融合结果。通过仿真实验证明,该方法能够有效处理冲突证据,并获得更好的融合结果。
Because of its defect ,the original evidence theory won't work or made an unexpected result when facing the conflict evidence.For this problem, a modified evidence theory is proposed,which can generate new weights by combining ambiguity measure and confidence distance. New weights can be used to modify the conflict evidence to get a better fusion result. This method is proved that it can handle the conflict evidence and the fusion result is better than before through the simulation.
