An Exact Method for Solving Selective Maintenance Problems Considering Imperfect Maintenance
2016 International Conference on Intelligent Networking and Collaborative Systems (INCoS), 2016In the past few decades, analytical models for maintenance optimization have been extensively investigated. As research continues, the cases considered during the mathematical modeling are much more practical, as well as complex, which brings many difficulties for solution. In this paper, we present an exact method for solving the selective maintenance

Imperfect Preventive Maintenance Models
2000This chapter surveys the earlier results of imperfect preventive maintenance (pm) models which could be applied to actual systems; (i) the unit after pm has the same hazard rate as before pm, (ii) the age of the unit becomes x units of time younger at pm, and (iii) the age reduces to at when it was t before pm.

Selective maintenance optimization when quality of imperfect maintenance actions are stochastic
Reliability Engineering & System Safety, 2016Abstract This paper addresses the selective maintenance optimization problem in a multi-component system, carrying out several missions with scheduled inter-mission breaks. To improve the probability of the system successfully completing the next mission, maintenance is performed on the system׳s components during the break. Each component is assigned

Imperfect repair models with preventive maintenance
Journal of Applied Probability, 2003Brown 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 ...

Selective Maintenance for Systems under Imperfect Maintenance Policy
2014Due to the advent of complex engineering systems in the last few decades, reliability and maintenance issues are gaining more attention than ever. Maintenance is important to keep a system running and ensure that it performs its functions satisfactorily. Often, there are limited resources to complete the maintenance of a system.

Optimum Policies When Preventive Maintenance is Imperfect
IEEE Transactions on Reliability, 1979This paper considers three models with imperfect preventive maintenance (pm), viz the unit after pm is not always like new; i) the unit is repaired upon failure, ii) the unit undergoes minimal repair at failure, and iii) the failed unit is detected only by perfect pm.

Maintenance optimization in failure-prone systems under imperfect preventive maintenance
Journal of Intelligent Manufacturing, 2018In the majority of the existing preventive optimization models only costs related to maintenance actions are accounted for, while breakdown and operational costs are usually ignored. Liao et al. (J Intell Manuf 21(6):875–884, 2010) proposed a preventive maintenance model to deal with this shortcoming.
