In this investigation, the machine repair problem with mixed spares and additional repairmen under no passing constraints have been studied. We assume that there are M operating machines, S cold and Y warm spares machines maintained by R permanent repairmen. In case when all spares are being used, the failure of machines occurs in degraded fashion. In such a situation there is provision of r additional repairmen to speed up the repair. There may be restriction on the departing customers who have to leave the system in the sequential order of the arrival. By using reneging parameters our model becomes closer to the real congestion life situation. The expressions for determining the average number of idle machines, the average number of idle repairmen and waiting time, etc. are established.
