Condition‐Based Maintenance with Imperfect Preventive Repairs for a Deteriorating Production System

This paper presents a condition‐based maintenance policy considering aspects of maintenance cost and productivity for a single‐unit deteriorating production system whose condition is periodically monitored. Imperfect preventive maintenance actions, which restore the production system to better than old, are considered with both deterministic and random intervention gains. Moreover, the system is assumed to be repaired only a limited number of times. In order to assess the performance of the proposed maintenance policy, different types of imperfect preventive maintenance cost functions are investigated. A numerical example of a multi‐state production system is finally introduced to illustrate the use and the advantages of the proposed policy. Copyright © 2012 John Wiley & Sons, Ltd.
