Optimal Maintenance Policy with Imperfect Preventive Maintenance

IEEE Transactions on Reliability, 1981
This 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, 2014
The 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.

Optimization of equal-cycle maintenance strategy considering imperfect preventive maintenance

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2021
Preventive maintenance is an important means to extend equipment life and improve equipment reliability. Traditional preventive maintenance decision-making is often based on components or the entire system, the granularity is too large and the decision-making is not accurate enough. The meta-action unit is more refined than the component or system, so

Optimal Age-Policy with Imperfect Preventive Maintenance

IEEE Transactions on Reliability, 1981
We 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.

On an imperfect preventive maintenance model

International Journal of Quality & Reliability Management, 2000
Presents 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.
