An imperfect maintenance model with block replacements

Abstract: We consider a model in which when a device fails it is either repaired to its condition prior to failure or replaced. Moreover, the device is replaced at times kT, k = 1, 2, … The decision to repair or replace the device at failure depends on the age of the device at failure. We find the optimal block time, T0, that minimizes the long‐run average cost of maintenance per unit time. Our results are shown to extend many of the well known results for block replacement policies.
