Abstract: In this article we address the problem of optimally controlling the service rate in a service facility system maintaining perishable inventory for service completion. We consider a finite service facility system having finite waiting space with Poisson arrivals and exponentially distributed service times and lif e time of items. For the given values of maximum inventory and waiting space capacity, we determine the order quantities at various instance of time so that the long run expected cost rate is minimized. The problem is modeled as a semi–Markov Decision Problem. We prove the existence of a stationary optimal policy and solve it by employing value iteration technique. Numerical example is provided to get insight into the system behavior.
