SFT中故障及其影响因素的背景关系分析
Analysis of background relationship between fault and its influencing factors in SFT
摘要
Abstract
In order to make the SFT has the ability of intelligent reasoning,based on the basic principle of the analysis of the background relationship in factor space,this paper put forward analysis method to analyze the fault and its influencing factors of actual fault data.It made affecting fault factors as affecting factors and made failure probability as the target factors.Through the establishment of the phase space,it established the background relationship state corresponding table to analyze the background relationship.It calculated factor marginal distribution and obtained influence situation from affecting factors to target factors.This method can get the influence degree of the influence factors on the target factors through the qualitative analysis and according to the fault state frequency.It obtained the last influence about analysis working time and temperature effected on the failure probability by the example,and gave of the specific process the analysis.关键词
