Optimal maintenance period and maintenance sequence planning under imperfect maintenance
Quality and Reliability Engineering International, 2022AbstractMaintenance is essential for today's equipment or systems and maintenance costs account for a significant portion of the overall expenditure of devices. Maintenance period optimization and maintenance sequence planning are primary aspects of maintainability.

Optimal Maintenance Policy with Imperfect Preventive Maintenance
IEEE Transactions on Reliability, 1981This paper considers a maintenance policy with imperfect preventive maintenance (pm). After pm, the failure characteristic of the system is different (worse) from that of correctively maintained system (viz. after a failure). Optimal policy which minimizes the mean cost-rate is discussed.

Optimal Maintenance Time Under Imperfect Preventive Maintenance
Vulnerability, Uncertainty, and Risk, 2014The preventive maintenance (PM) is scheduled periodically to restore the system condition. However, PM activities cannot generally restore the system to as good as new condition but in an intermediate situation, which is called imperfect PM. The PM interval optimization is useful for improving system reliability.

Optimal maintenance—replacement policy under imperfect maintenance
Reliability Engineering & System Safety, 1992Abstract During a given planning period, in order to have the system working at or below a fixed failure rate, it may be necessary to replace the system to minimize the expected total cost. Preventive maintenance (PM) or replacement should be performed whenever the system reaches the maximum failure rate.

Imperfect Preventive-Maintenance
IEEE Transactions on Reliability, 1979This paper considers a periodic preventive maintenance (pm) policy with ``minimal repair'' at failure; pm is imperfect. A special case of failure (hazard) rate improvement is postulated wherein pm reduces the failure rate, but does not return the time origin all the way to zero.

Reliability-based maintenance optimization under imperfect predictive maintenance
Chinese Journal of Mechanical Engineering, 2012The reliability-based maintenance optimization model has been focused by the engineers and scholars but it has never been solved effectively to formulate the effect of a maintenance action on the optimization model. In existing works, the system reliability was assumed to be increased to 1 after a predictive maintenance.

Condition-Based Maintenance with both Perfect and Imperfect Maintenance Actions
Annual Conference of the PHM Society, 2012This paper deals with a condition-based maintenance (CBM) model considering both perfect and imperfect maintenance actions for a deteriorating system whose condition is aperiod- ically monitored according to a remaining useful life (RUL) based-inspection policy.

Optimal Age-Policy with Imperfect Preventive Maintenance
IEEE Transactions on Reliability, 1981We study the optimal age policy with imperfect preventive maintenance. The preventive maintenance is imperfect in the sense that it can cause failure of a non-failed system.
