In this paper, we deal with a preventive maintenance (PM) scheduling problem for a rolling stock system. We determine the optimal PM intervals for components in the rolling stock system. The system availability and life cycle cost are used as optimization criteria. For given three PM intervals, we assign a suitable interval to each component to minimize the system life cycle cost and to satisfy the required system availability. The system availability and system life cycle cost are estimated by simulation. A heuristic method is proposed to find the optimal PM intervals of all components. Numerical examples are also studied.
