| 摘 要： | 为了解决在多传感器信息融合处理故障诊断过程中,传统证据理论对含有冲突证据的处理结果与实际相悖的问题,介绍了传统D-S证据理论的基本构架,分析了其在处理含有高冲突的证据融合过程中将高信任度分配给小可能故障源的不足,提出了一种新的基于模糊成员函数和证据平均距离的证据调整方法,该模糊成员函数充分考虑了专家知识对基本概率分配函... |

| Abstract: | In order to solve the problem that it is inconsistent with the facts when the conventional evidence theory is used to deal with evidences of high conflict in the multi-sensor information fusion fault diagnosis system.This paper introduces the basic framework of the Dempster-Shafer(D-S) evidence theory and analyzes shortcomings of assigning high believe probability to fault source of small possibility in the course of dealing with fusion of evidences of high conflict using the D-S evidence theory.A new metho... |
