摘要
由N个不同部件并联组成系统,各部件失效率分别为(λ1,λ2,…,λn),修复率分别为(μ1,μ2,…,μn)。假定在Δt时间内系统不会同时出现两个以上部件失效,若只有一组维修人员且不能同时修复两个以上失效部件,根据基于马尔可夫过程的系统状态转移图,则共有(n+1)个状态。
Maintainability system is composed of N various components of parallel connection, failure ratio of each components respectively isλ1,λ2,…,λn, maintenance rate isμ1,μ2,…,μn. Assumed in Δt time, the system does not appear failures of two upwards components at one time, if there is only a set of maintainers, it does not maintain two upwards failure components at one time, state transition diagram of system is analyzed according to Markov process to gain n+1 states.
