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.

Continuous degradation modeling under random shocks and imperfect maintenance using generalized renewal process

Journal of Quality in Maintenance Engineering
PurposeThe idea is to develop a condition-based maintenance (CBM) model for continuously monitored degrading systems under imperfect maintenance. The system is subjected to random shocks, inspection, corrective maintenance (CM) and preventive maintenance

Optimal maintenance—replacement policy under imperfect maintenance

Reliability Engineering & System Safety, 1992
Abstract 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.

Selective maintenance optimization for multi-state systems considering stochastically dependent components and stochastic imperfect maintenance actions

Reliability Engineering & System Safety, 2020
This paper presents a selective maintenance optimization problem for complex systems composed of stochastically dependent components. The components of a complex system degrade during mission time, and their degradation states vary from perfect ...

Data-Driven Time Dependent Reliability Prediction Approach for Overhead Contact Lines Subjected to Imperfect Maintenance, Common Cause Failure and Lightning Strike

IEEE Transactions on Power Delivery
To ensure the high-reliability operation of overhead contact lines (OCLs), this paper proposes a data-driven time dependent reliability prediction approach, incorporating the maintenance factor, common cause failure (CCF), and lightning strike into ...

Optimal maintenance decisions under imperfect inspection

Reliability Engineering & System Safety, 2005
The process industry is increasingly making use of Risk Based Inspection (RBI) techniques to develop cost and/or safety optimal inspection plans. This paper proposes an adaptive Bayesian decision model to determine these optimal inspection plans under uncertain deterioration.

Optimal Policies With Decreasing Probability of Imperfect Maintenance

IEEE Transactions on Reliability, 2005
This study applies periodic preventive maintenance to three repair models: major repaired, minimal repaired, or fixed until perfect preventive maintenance upon failure. Two types of preventive maintenance are performed, namely imperfect preventive maintenance, and perfect preventive maintenance.

Reliability and maintainability estimation of a multi‐failure‐cause system under imperfect maintenance

Quality and Reliability Engineering International
Estimating the reliability and maintainability (R & M) parameters is crucial in various industrial applications. It serves purposes such as evaluating system performance and safety, minimising the risk and cost of potential failures, and designing ...

IMPERFECT PRODUCTION SYSTEMS WITH IMPERFECT PREVENTIVE MAINTENANCE, INFLATION, AND TIME VALUE OF MONEY [PDF]

Asia-Pacific Journal of Operational Research, 2006
A model that integrates the issues of production, quality, maintenance, inspection, inflation, and time value of money is proposed in this paper. It is assumed that the production system starts in the in-control state producing items of high or perfect quality.
