Abstract: With the supplementary variable method, reliability analysis of a n-unit series repairable system with finite number of vacations is discussed. Some main reliability indexes of the system are obtained, such as the availability, the failure frequency, the probability that the system is waiting for repair, and the expected renewal time. Furthermore, special cases of the model are given and the profit of the system is considered.

Key words: OR, series system with vacations, supplementary variable method, failure frequency, profit
