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.

A predictive maintenance policy with imperfect monitoring

Reliability Engineering & System Safety, 2010
For many systems, failure is a very dangerous or costly event. To reduce the occurrence of this event, it is necessary to implement a preventive maintenance policy to replace the critical elements before failure. Since elements do not often exhibit incipient faults, they are replaced before a complete exploiting of their useful life.

Optimal lot-sizing problem with imperfect maintenance and imperfect production

International Journal of Systems Science, 2004
In this paper, we develop an integrated model for the joint determination of both economic production quantity and level of preventive maintenance (PM) for an imperfect production process. This process has a general deterioration distribution with increasing hazard rate.

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 Preventive-Maintenance

IEEE Transactions on Reliability, 1979
This paper considers a periodic preventive maintenance (pm) policy with ``minimal repair'' at failure; pm is imperfect. A special case of failure (hazard) rate improvement is postulated wherein pm reduces the failure rate, but does not return the time origin all the way to zero.
