为了在获得少故障数据条件下得到适合的系统故障演化过程(system fault evolution process,SFEP)中最终事件发生概率分布,提出一种考虑信息扩散且数据较少情况下的最终事件发生概率分布计算方法。该方法利用信息扩散原理以事件发生时因素为中心在研究区域内形成正态分布。同一事件的多次发生在研究区域中取最大值形成该事件发生概率分布,从而得到SFEP中边缘事件发生概率分布。将SFN中事件关系表示为关系组从而叠加关系,得到最终事件发生概率分布解析式计算分布。研究表明,所得结果与原有精确结果具有较高的符合性,但所需故障数据则少得多。可借助该方法在少故障数据条件下研究SFEP最终事件发生特征。

To get suitable probability distribution of the target event in the system fault evolution process (SFEP) with less fault data, we propose a calculation method of the probability distribution of the target event occurrence considering the information diffusion and less data. This method uses the information diffusion principle to form a normal distribution in the study area with the factors at the event occurrence as the center. Take the maximum value for many times of occurrence of the same event in the study area, forming the probability distribution of the event occurrence. Thereby, the probability distribution of the edge event occurrence in the SFEP is obtained. The event relationships in SFN are expressed as relationship set and then the relationships are superposed, and the analytic formula of probability distribution of target event occurrence is obtained. The research shows that the results are in good agreement with the original accurate results with much less fault data. This method can be used to study the target event occurrence characteristics of SFEP under the condition of less fault data.
