This paper studies a condition-based predictive maintenance policy in the presence of imperfect repairs for deteriorating systems. The effect is assumed to be random sense that action reduces systems degradation level by proportion. associated distribution allows characterizing repair efficiency. As an example, beta considered. It defining wide range efficiencies. A with aperiodic and inspectio...

This paper investigates the effects of preventive-maintenance cost functions on the optimal preventive-maintenance policy for a leased product with Weibull life-time distribution. During the lease period, any product failures are rectified by minimal repairs and may incur a penalty to the lessor, if the time duration for performing a minimal repair exceeds a pre-specified time limit. To reduce ...

This paper presents the stochastic analysis of a two unit parallel system model with the concept of correlation between time to preventive maintenance and preventive maintenance time. The joint distribution of time to preventive maintenance and preventive maintenance time is taken bivariate exponential. Using regenerative point technique, various measures of system effectiveness useful to syste...

Preventive maintenance is the essential part of many maintenance plans. From the production point of view, the flexibility of the maintenance intervals enhances the manufacturing efficiency. On the contrary, the maintenance departments tend to know the timing of the long term maintenance plans as certain as possible. In a single-machine production environment, this paper proposes a simulation–o...
