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.

Optimal maintenance period and maintenance sequence planning under imperfect maintenance

Quality and Reliability Engineering International, 2022
AbstractMaintenance is essential for today's equipment or systems and maintenance costs account for a significant portion of the overall expenditure of devices. Maintenance period optimization and maintenance sequence planning are primary aspects of maintainability.

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.

Optimum Policies for a System with Imperfect Maintenance

IEEE Transactions on Reliability, 1987
This paper considers a system with imperfect maintenance, i.e., after maintenance the system may be either (a) not changed, or (b) failed, with certain probabilities. Formulas for the MTTF and the availability are obtained and the policy to maximize availability is derived. A numerical example applies these results to a triple redundant system.
