摘　　要：首先在转换开关完全可靠、转换开关寿命连续型和转换开关寿命0-1型3种情形下讨论不可修系统的可靠性指标得到可靠度的表达式,然后在一定的假设条件下讨论可修系统,运用马尔可夫系统理论讨论系统状态的定义、转移概率的计算,进一步探讨求解系统可靠性瞬时和稳态指标,最后以5部件组成的系统作为实例系统地讨论本系统可靠性指标的计算。It discussed unrepairable system in three cases,including the completely reliable switch,the continuous lifetime switch,and the 0-1type lifetime switch.The system reliabilities were obtains respectively.Then we discussed repairable system under certain assumptions.Using Markov process theory,it defined system states.State transition probabilities were calculated.Some important reliability indexes and some steady state system indexes ccould be derived.Finally,an example with five components was given to illustrate the theoretical results of the model.
