【摘要】 针对当前工程领域中存在大量离散问题,提出了时间参数为离散的假设,然后对单部件可修系统进行了研究,利用更新过程的方法,建立了基于故障率和修复率的系统状态转移模型。在此基础上得到了系统可靠度、可用度、平均故障次数等可靠性指标。最后,该文给出一个数值仿真来说明上述模型的有效性。更多还原

【Abstract】 The time parameter is assumed to be discrete as there are many discrete-time problems in engineering community,but the existing theory only gives us methods in continuous-time systems.Considering the one-unit discrete time repairable systems,this paper proposes a state transition model based on failure rate and repairable rate.The reliability performances such as reliability,availability of the system and the mean failure times are obtained.An example is given to illustrate the effectiveness of the proposed model.更多还原
