Remaining useful life (RUL) based maintenance decision making for deteriorating systems

This paper deals with a remaining useful life (RUL) based maintenance policy for single unit deteriorating systems whose condition are periodically monitored. Thank to the RUL information, which is estimated from the available monitoring information, various decisions related to inspections, logistic support, maintenance opportunities and maintenance actions are considered in the proposed policy. To illustrate the use and the advantages of the proposed maintenance policy, different sensitivity studies are analyzed and discussed through a numerical example. A comparaison with a classical condition based maintenance policy is also investigated.
