Abstract

The cost-benefit analysis of a 1-server n-unit system has been carried out under the assumption that the repair time distribution of a unit is general while the failure time distribution of a unit is exponentially distributed. The service facility is called for whenever r(0 ≤r ≤ n ) units are in a failed condition and is retained until no unit is waiting for repair. The s-expected busy period of the service facility, s-expected uptime of the system and the availability of the system under different policies are obtained by using the regenerative technique. The particular case when n = 2 and the repair time distribution is two-stage Erlangian is discussed. Numerical results pertaining to the above case have been obtained.
