| 摘 要： | 本文在故障树定性和定量分析基础上，提出了基于故障树的智能型故障诊断方法。该方法是建立在故障模式按发生概率大小排序和底事件按发生概率大小排序基础上，因此较好地反映了故障诊断过程中各个底事件和中间事件对系统故障的影响。

| Abstract: | Fault tree analysis is a technique by which many events that interact to produce other events can be related using simple logical relationships;these relationships permit a methodical building of a structure that represents the system.Based on qualitative and quantitative analysis of fault tree,a kind of intelligent fault diagnosis method is presented in this paper.Minimal cut sets are queued by their occurrence probabilities.And basic events are queued by their critical importance factor.Diagnosis result is derived from the queued sequential access method. |

| Keywords: | Fault tree analysis Fault diagnosis Minimal cut set |
