Control-limit preventive maintenance policies for components subject to imperfect preventive maintenance and variable operational conditions

Reliability Engineering and System Safety, 2011
This paper develops two component-level control-limit preventive maintenance (PM) policies for systems subject to the joint effect of partial recovery PM acts (imperfect PM acts) and variable operational conditions, and investigates the properties of the proposed policies.

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.

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.

Imperfect repair models with preventive maintenance

Journal of Applied Probability, 2003
Brown and Proschan (1983) introduced the imperfect repair model, in which an item, upon failure, is replaced with a new one with probability α, and is minimally repaired with probability 1 − α. In this paper we equip the imperfect repair model with preventive maintenance, and we obtain stochastic maintenance comparisons for the numbers of failures ...

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.

Modelling and analysis of maintenance contract with imperfect preventive maintenance

2015 International Conference on Technology, Informatics, Management, Engineering & Environment (TIME-E), 2015
In 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.

Scheduling Imperfect Preventive and Overhaul Maintenance

International Journal of Quality & Reliability Management, 1991
Although each maintenance task performed on an item of equipment may enhance its reliability, neither preventive nor overhaul maintenance can return the equipment to good‐as‐new condition. Applying the concept of maintenance improvement factors to both types of maintenance, mathematical models are developed that are used to generate preventive and ...

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.

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

Scheduling Preventive Maintenance as a Function of an Imperfect Inspection Interval

IEEE Transactions on Reliability, 2015
This paper considers a system with periodic inspections and periodic preventive maintenance (PM) to detect and correct hidden failures that generate a penalty cost per unit time undetected. Imperfect periodic inspections (IPIs) occur at a chosen interval $t$ , and detect hidden failures with probability $p\in (0,1)$ .
