Optimizing Preventive Maintenance Models
We deal with the problem of scheduling preventive maintenance (PM) for a system so that, over its operating life, we minimize a performance function which reflects repair and replacement costs as well as the costs of the PM itself. It is assumed that a hazard rate model is known which predicts the frequency of system failure as a function of age. It is also assumed that each PM produces a step ...
متن کاملPreventive maintenance models with random maintenance quality
In real-world environments it is usually difficult to specify the quality of a preventive maintenance (PM) action precisely. This uncertainty makes it problematic to optimise maintenance policy. This problem is tackled in this paper by assuming that the quality of a PM action is a random variable following a probability distribution. Two frequently studied PM models, a failure rate PM model and...

متن کاملControl-limit preventive maintenance policies for components subject to imperfect preventive maintenance and variable operational conditions
This paper develops two component-level control-limit preventive maintenance (PM) policies for systems subject to the joint effect of partial recovery PM acts (imperfect PM acts) and variable operational conditions, and investigates the properties of the proposed policies. The extended proportional hazards model (EPHM) is used to model the system failure likelihood influenced by both factors. S...
متن کاملA SUMMARY OF OPTIMUM PREVENTIVE MAINTENANCE POLICIES MAXIMIZING INTgRVAL RELIABILITY
This paper considers the interval reliability of a repai:rable system for the time interval [T, T+xl. Optimum preventive maintenance policies maximizing (i) the limiting inten'al reliability when T is constant, and (ii) the interval reliability when T is exponential, and minimizing (iii) the expect,ed cost per unit of time, are derive;\. It is shown that under suitable conditions there exist op...
