基于Markov和SFT的同类元件系统中元件维修率分布确定
Determine component maintenance rate distribution in similar components system based on Markov and SFT
摘要
Abstract
In order to expand the space fault tree SFT,and study component maintenance rate according to the environmental impact,this paper derived component maintenance rate distribution using Markov chain theory.The characteristics of studied system were composed of the same components,then the components had the same failure rate and repaired rate of Markov chain.It substituted the SFT characteristic function of the failure rate in Markov chains,and set the state transition probability considering actual situation,to obtain the components maintenance rate distribution.Repair rate distribution was a function by the work environment factors as the independent variables.Considering the influence of the working time t and temperature c,this paper calculated the component maintenance rate distribution of hybrid system and obtained the component repair rate distribution and the normal state transition probability range.Finally this paper discussed the method's disadvantages and the reasons.关键词
