摘要：This paper considers a two component load-sharing system. The load and components failure rate are time dependent. It proposes a maintenance policy considering minimal repairs, imperfect maintenance and replacements. The existence of the optimal cost rate in the long run is proved. The optimal maintenance results are derived from the theoretical propositions and the sensitivity of the system parameters to the maintenance policy optimization criteria is pointed out.
