基于Jousselme距离的证据理论决策方法

Decision method of evidence theory based on Jousselme distance

针对证据理论融合结果的决策问题,提出了利用Jousselme距离对融合结果进行决策的方法。首先把辨识框架中的元素表示为目标证据,然后计算融合结果与目标证据之间的Jousselme距离,当距离最小时对应一个目标证据,此目标证据对应的元素即为最终的决策结果。仿真算例表明该方法可以得到合理的决策结果。

A decision method using the Jousselme distance is proposed to deal with the decision of the evidence theory fusion result. Firstly,transform every element of the discernment frame into the object evidence.Then calculate the Jousselme distance between the fusion results and every object evidence. When the distance is the nearest,the corresponding element of the object evidence is the decision result. Simulation calculation examples indicate that this method could complete the decision work.
