Life Prediction of Carrier-Based Aircraft Replaceable Units With Time-Varying Drift and Optimization Strategy for Imperfect Maintenance

IEEE Transactions on Reliability
The aircraft is the sharpest sword of the carrier, and the lifetime of the replaceable units determines its availability. At present, few studies refer to the hybrid impact of maintenance and degradation on the lifetime. This article proposes a model for

Condition-Based Maintenance with both Perfect and Imperfect Maintenance Actions

Annual Conference of the PHM Society, 2012
This 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.

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 ...

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.

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.

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.

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.
