Abstract:

A replacement model for a oneunit repairable system equipped with a repairman who has multiple vacations is proposed. Repair upon failure might not be immediately carried due to the fact that the repairman might be on vacation. The system might therefore be at one of the three states:working, being repaired, and waiting for repair. Suppose that the system cannot be repaired as good as new and a repair can be delayed with a probability of 1-p, an explicit expected cost rate using an extended geometric process and N replacement policy is given. Numerical examples are also used to validate the replacement policy.
