Abstract: The talk focuses on theoretical properties of a well-spread imperfect maintenance model named ARA Infinite. The new results are applied to two configurations often observed in practice. Firstly, many systems are not necessarily new at the beginning of their observations (second-hand units, missing data). However, the classical modellings usually assume either that the system is new at the beginning of the observations or that no failure/maintenance has been carried out since the startup of the system. Secondly, preventive maintenance schedules always assume that the system has to be fully renovated (renewal point) during the life course of the system. The new developments of the ARA Infinite model allow to study repairable systems which are not new at the beginning of the observation and to implement an optimal preventive maintenance schedule over an infinite planning horizon with imperfect maintenance only.
