Condition-based maintenance under an imperfect repair policy for a deteriorating production system

This paper presents a condition-based maintenance policy taking into account both maintenance cost and production capacity aspects for single unit deterioratin production system whose condition is periodically monitored. Imperfect preventive maintenance activities, which restore the production system to better states and might not be as good as new, are considered. We assume however that the system can be repaired only a limited number of times. In order to access the performance of the proposed maintenance policy, both linear and non-linear imperfect preventive maintenance cost functions are investigated. A numerical example of a multi state production system is finally introduced to illustrate the performance of the proposed policy.
