Abstract Research on machine-repair model including the use of spares with repairmen's performing secondary task was carried out, which was regarded as a finite queue with servers vacations by using the method of quasi-birth and death process. The stable distributions of the number of break-down machines and the time waiting for repair were obtained. Finally the author figured out that the model degenerated to some special cases in given situation and then provided their stable distributions.
