Reliability Analysis Of Repairable System With Priority And A Repairman Doing Other Work

Reliability of repairable system is very important in the research of reliability. The voting repairable system and cold standby repairable system are the two of the most important repairable systems. On the base of the existing research harvest of repairable system, the paper has extended some system reliability of repairable models.Firstly, this paper discusses a repairable linear C (3 , 2:G) system and cold standby repairable system with a repairman doing other work. Under the condition of different repairment, it is assumed that one component after repair is as good as new, otherwise the others after repair is not as good as new in linear C (3 , 2:G) system. The cold standby system is formed by two same components. It is assumed that the working time of each component and the arrival interval time distributions of the customers are to be exponential distributions, the others are to be general continuous distributions in the system.By using supplementary variable method, the general Markov process method and the tool of the Laplace transform, several reliability indices of this model was obtained: the availability, the stead-state failure frequency and so on.Based on these papers, this paper discusses cold standby repairable system which is formed by two different components, It is assumed one component after repair is not as good as new, we discussed cold standby system with using priority. We further discussed the cold standby repairable system with using priority, repairing priority and the repairman doing other work. The system is formed by two different components. It is assumed that the lifetime distributions of components are all exponentially distributed, and the repair time of components and the work time of the repairman outside the system are all generally distributed. Using Probability Theory and the method of Laplace transformation theory, we obtain the reliability indexes of this system.
