D-S证据理论中冲突问题的解决方法

Conflict Solution in D-S Evidence Theory

针对传统D-S证据理论中冲突证据合成存在的问题,提出一种基于数学模型修正证据源的冲突证据合成方法。在不改变Dempster组合规则的前提下,逐一比较识别元素的基本概率分配值和平均基本概率分配值,结合数学模型修正基本概率分配。仿真结果表明,该方法在处理冲突证据合成时有效、可行。

In order to solve the problem of the conflict evidence synthesis in the traditional D-S evidence theory,this paper proposes a novel approach based on the mathematical model to modify the evidence source. This approach compares the basic probability assignment value of focus and the average basic probability assignment value of focus, and corrects the basic probability assignment value of focus by a new mathematical model. The simulation result show that the proposed approach is effective and feasible for dealing with conflict evidence synthesis.
