| Tiivistelmä: | In this paper, the authors study a modified minimal repair/replacement problem that is formulated as a Markov decision process. The operating cost is assumes to be a nondecreasing function of the system's age. The specific maintenance actions for a manufacturing system to be considered are whether to have replacement, minimal repair or keep it operating. It is shown that a control limit policy, or in particular a (t, T) policy, is optimal over over the space of all possible policies under the discounted cost criterion. |
