| Tiivistelmä: | A single-server queuing system with general service times is considered. While the server is up, it is subject to breakdowns. When the server breaks down, there are two repair operations. The operating costs of the system include customer holding costs, repair costs and running costs. The objective is to find a policy that minimizes the long-run average operating costs of the system. An optimal stationary policy is proved to exist, characterized by a single threshold parameter. It is referred to as monotone. The faster repair is used if and only if the number of customers in the system exceeds this threshold. An efficient algorithm is presented for the determination of an optimal monotone policy and its average cost. |
