摘　　要：针对离散时间下由n个不同部件组成的串联可修系统,假定系统中任一部件的故障率和修复率都为正的常数,本文建立了基于故障率和修复率的系统状态转移模型。然后,在此基础上推导出系统可靠度、系统首次故障前平均时间和瞬时可用度等可靠性指标。最后,给出一组算例来说明该模型。This paper discusses an n-unit discrete-time serial repairable system in which the failure rate and repair rate of each unit are all supposed to be non-negative constants. A state transition model is proposed based on failure rate and repair rate. The reliability performances such as reliability, mean time to first failure （MTTFF） and instantaneous availability of the system are obtained via the proposed model. Some textbook examples are given to illustrate the new model.
