Some Extensions of Markov Repair Models.
Abstract
In this paper, two different kinds of discrete time maintenance models with repair shops are studied. The first type of model has a multiple number of repair shops in the system. When information on the type of repair required is available at the moment of each decision, simple optimal maintenance policies are obtained under the mild conditions. On the other hand very restrictive conditions are required for the case when such information is not available. In the next model considered, the action space is expanded to include the option of opening or closing the repair service gate, as well as the option of repairing or leaving an operating machine alone. A two-dimensional control limit policy is defined, and the optimality of such a control limit policy is assured when the repair time of a machine is negligibly small, a very reasonable condition. When the repair time is not negligible, but has a geometric distribution, a restrictive condition on the holding costs must be satisfied. (Author)
