文章研究了带有多个温贮备部件的机器维修问题,系统中有R个修理工,修理工进行N-策略休假.同时还考虑了故障部件止步和中途退出的现象.文中利用Markov过程理论建立了系统状态概率满足的微分差分方程组,利用矩阵理论和Laplace变换反演的方法求解出了系统故障状态概率的精确表达式,得到了系统可靠度及首次故障前的平均时间的精确表达式,并给出了数值结果. In this paper, the problem of machine maintenance with multiple temperature reserve components is studied. In the system, there are R mechanics and N-strategists on vacation. At the same time, the phenomenon of stopping and halting of the faulty components is also considered. In this paper, Markov process theory is used to establish the system The exact differential state of the differential equations, the use of matrix theory and Laplace transform inversion method to solve the exact expression of the system fault state probability, the system reliability and the average time before the failure of the exact expression, and to The numerical results.
