有效处理冲突证据的融合方法

Efficient fusion approach for conflicting evidence

为解决Dempster-Shafer证据理论在对高度冲突的证据进行融合时可能导致与直观结果相悖的问题,该文提出了一种有效处理冲突证据的融合方法。该方法综合了Dempster-Shafer证据理论所具有的收敛性好及加性融合方法所具有的可靠性高的优点,首先通过对证据进行冲突检验,然后对冲突证据进行加性合成,消除证据之间的冲突。仿真试验结果表明该算法能更好地排除干扰,得出符合实际的组合结果,与典型算法相比,该方法在收敛性和可靠性方面体现了优越性。

A method was developed for dealing with seriously conflicting evidence when the Dempster-Shafer combination result can not identify the actual conditions. The method utilizes the advantages of the Dempster-Shafer evidence theory and an additive strategy. The conflicting evidence was first verified and then the additive strategy was used to modify the properties of the conflicting evidence. Simulation and tests show that accurate identification results can be achieved by this method when the evidence seriously conflicts. This method improves the reliability and rationality of combination results compared with traditional methods.
