| Abstract: | A repairable system is considered in which the repairmen can be selected randomly and the repair can be delayed.Assuming that the working life,the repair delay time and the repair time have all the broad sense exponential distribution,some main reliability index of the system,such as availability,reliability,repairable frequency and the probability of repair delay,are derived by using the supplementary variable technique,the broad sense Markov process and the tool of the Laplace transform. |
