摘要
研究了具有两水平修理策略和两类修理工的表决可修系统,其中部件的工作时间和修理时间均服从负指数分布.使用马尔可夫分析方法和马氏链吸收时间理论,讨论了系统可用度、故障频度、首次故障前的平均时间等指标.在此基础上,分析了不同条件下系统相关指标随系统参数变化的情况.最后,通过蒙特卡罗仿真和特殊情形的数值结果验证了所得表达式的正确性.
This paper investigates a repairable system with bi-level repair strategy and two types of repairmen,in which the working times and repair times of components follow exponential distributions. Employing the Markov analysis method and the theory of the absorption time of a Markov chain, this paper discusses the system availability, the rate of occurrence of failures of the system, the mean time prior to failure of the system and some other system performance measures. Further, this paper also analyzes the influence of system parameters on system reliability measures. Finally, Monte Carlo simulation and special cases are provided to show the correctness of the theoretical results.
