  • The reliability for a cold standby n-component repairable system with a repairman having multiple vacations is studied. If all of units are in normal state, the repairman may take his vacations, and the vacation time is a random variable. During the repairman's vacation, if a unit online fails to work, one of cold standby components becomes the component online immediately the failure unit will not be repaired until the repairman comes back from his vacation. The operational time of the unit online, the repair time and the vacation time of repairman are governed by different phase-type (PH) distributions, respectively. The system is studied in a transient and stationary regime. The reliability, availability, rate of occurrence of failures and busy probability of repairman are derived by Kronecker operator and Markov process theory. A numerical example is given to illustrate the results obtained.
