Abstract

The main intention of this paper is to develop a cost-benefit analysis for a single-server two-unit system subject to arbitrary failure, inspection and repair. The service facility is called for whenever (i) a unit fails, (ii) the system fails and is retained until no unit is waiting for service. Various system parameters or vital significance, such as point-wise availability of the system at any instant t, s-expected up-time of the system, s-expected inspection time of the server, s-expected type i (i = 1, 2) repair time of the server and s-expected net gain per unit time in a specified time span, say (0,t] have been obtained. Regeneration point technique is adopted to carry out the analysis. Numerical results pertaining to the case when failure and inspection times are exponentially distributed while repair times are distributed as two-stage Erlangian have been obtained.
