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.

Optimum Policies for a System with Imperfect Maintenance
IEEE Transactions on Reliability, 1987This paper considers a system with imperfect maintenance, i.e., after maintenance the system may be either (a) not changed, or (b) failed, with certain probabilities. Formulas for the MTTF and the availability are obtained and the policy to maximize availability is derived. A numerical example applies these results to a triple redundant system.

A predictive maintenance policy with imperfect monitoring
Reliability Engineering & System Safety, 2010For many systems, failure is a very dangerous or costly event. To reduce the occurrence of this event, it is necessary to implement a preventive maintenance policy to replace the critical elements before failure. Since elements do not often exhibit incipient faults, they are replaced before a complete exploiting of their useful life.

Optimal lot-sizing problem with imperfect maintenance and imperfect production
International Journal of Systems Science, 2004In this paper, we develop an integrated model for the joint determination of both economic production quantity and level of preventive maintenance (PM) for an imperfect production process. This process has a general deterioration distribution with increasing hazard rate.

A proactive condition-based maintenance strategy with both perfect and imperfect maintenance actions
Reliability Engineering and System Safety, 2015 International audienceThis paper deals with a proactive condition-based maintenance (CBM) considering both perfect and imperfect maintenance actions for a deteriorating system.

On an imperfect preventive maintenance model
International Journal of Quality & Reliability Management, 2000Presents two sequential preventive maintenance (PM) models. The first model can be viewed as an extension of Nakagawa’s model where the age reduction of the system is assumed to depend on the level of PM activities. Linear and nonlinear relationships between age reduction and PM level have been considered.

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.

Maintenance policies for protection systems with imperfect inspection and imperfect repair
Reliability Engineering & System SafetyIn this study, we investigate the optimal maintenance policies for stochastically deteriorating protection systems with imperfect inspections and imperfect repairs. We model the system's degradation as a continuous-time Markov chain with three states: good, poor, and failed.

Modelling and analysis of maintenance contract with imperfect preventive maintenance
2015 International Conference on Technology, Informatics, Management, Engineering & Environment (TIME-E), 2015In this paper, we study two dimensional maintenance contracts for a dump truck operated in a mining industry. To keep the truck in a good operational condition, an imperfect preventive maintenance (PM) policy is applied. When the truck fails then corrective maintenance (CM) is done.
