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...

this study investigates the coordination of production scheduling and maintenance planning in theflow shop scheduling environment. the problem is considered in a bi-objective form, minimizing themakespan as the production scheduling criterion and minimizing the system unavailability as themaintenance planning criterion. the time interval between consecutive maintenance activities as well as the...
