Some Extensions of Markov Repair Models ( Book )
1 edition published in 1976 in English and held by 1 WorldCat member library worldwide
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)

Markov Maintenance Models with Repair ( Book )
1 edition published in 1976 in English and held by 1 WorldCat member library worldwide
In this study discrete time finite state Markov maintenance models are investigated. In each model, a machine is assumed to be operating over time with its condition deteriorating as time goes on. The state of the machine is observed at the beginning of a period. An operating machine can be sent to a repair shop at this time, whereas a failed machine must be repaired. When a machine is being repaired, the number of time periods that it is unavailable is usually assumed to have a geometric distribution. A repaired machine becomes available in its best state. An operating cost is charged while a machine is operating, and material and labor costs are charged when it is being repaired. The objective is to find a policy which minimizes the total expected alpha-discounted cost or the long-rung average cost. Special emphasis is being placed on finding sufficient conditions to assure that a control limit policy is optimal. The aforementioned model had only one machine in the system. Models with spare machines in the system are next studied. For these models a penalty cost is added when the system fails (only when all machines are inoperative). (Author)
