| 摘 要： | 运用D-S证据理论将用不同模糊方法得出的诊断结果进行融合。试验证明，融合以后的结果比模糊方法得出的诊断结果误判率更低。运用D-S证据理论，可以减小因隶属度函数的不同而带来故障误判的可能性，从而更准确地判断故障原因。

| Abstract: | The diagnosis results of fuzzy methods are fused based on D-S evidence theory. It is shown that the faults can be diagnosed more accurately by the results of fusion than by the results of fuzzy methods. The error of the membership degree of faults resulted from the difference of the membership degree function can be reduced by D-S evidence theory. |
