Maintenance Model for Series System with Multiple Vacation and CCF

摘要

In order to achieve the long-run expected rewards and the average downtime of the system with repairman vacations and CCF, a series repairable system consisting of K identical components is studied. By the theories of renewal process and geometric process, the expressions of the long-run expected rewards and the average downtime of the system are studied. Finally, a numerical example is given to illustrate some theoretical results in this paper. The simulation demonstrates that the optimal policy M = (N_1,N_2,N_3,......N_k) is existed. It is useful for improving the rewards of company and the safety critical system to make rational use of resources and equipments.
