Optimum policies for a system with general imperfect maintenance

Reliability Engineering and System Safety, 2006
This study considers periodic preventive maintenance policies, which maximizes the availability of a repairable system with major repair at failure. Three types of preventive maintenance are performed, namely: imperfect preventive maintenance (IPM), perfect preventive maintenance (PPM) and failed preventive maintenance (FPM).

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 ...

Optimum Policies When Preventive Maintenance is Imperfect

IEEE Transactions on Reliability, 1979
This 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.

First hitting time distribution and cost assessment in a two-unit system with dependent degradation processes subject to imperfect maintenance

Proceedings of the Institution of Mechanical Engineers. Part O, Journal of risk and reliability, 2023
This paper proposes a degradation model for a two-unit series system, where the components exhibit dependence and are subject to imperfect maintenance. The interdependence between both components is captured using the trivariate reduction method.

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.

Modeling and solving the multi-objective energy-efficient production planning and scheduling with imperfect maintenance activities

Journal of Quality in Maintenance Engineering, 2023
PurposeThe purpose of this study is to propose a new mathematical model that integrates strategic decision-making with tactical-operational decision-making in order to optimize production and scheduling decisions.Design/methodology/approachThis study ...
