摘要:
Modified age replacement policies, where a system is not always as good as new after each maintenance, are discussed. The expected total discounted cost for an infinite time-span, introducing some costs and a continuous type discount rate is applied as a criterion of optimality, and the optimum policies minimizing this cost are obtained. It is shown that, under certain conditions, there exists a finite and unique optimum policy. Relations to the existing publications are also shown.
