一种修正的冲突证据融合方法

对于冲突证据,D-S证据理论无法使用甚至无法得出正确的结果,进而引发了专家学者的研究。针对该问题,提出了一种新的冲突证据融合方法,建立了多传感器综合可信度的计算模型,根据综合可信度得到多传感器的合成结果,采用D-S证据理论对合成结果进行组合,既解决了高冲突问题,又解决了低冲突问题。最后通过仿真验证了该方法的有效性。

A Modified Method of Conflict Evidence Fusion

Dempster-Shafer (D-S) evidence theory cannot be used and even provide correct results especially when evidences conflict highly. A new method which is used to handle with the conflict that appears during the course of combining information. Firstly,the computing model of integrated credibility of multi-sensor is built,and then the combined result of multi-sensor is used by Dempster-Shafer (D-S) evidence theory,which can solve both low and high conflict evidences. By some numerical examples,the new method has good performance in dealing with conflict and improves the reliability and rationality of the combination results.
