Matrix-based Methods for Planning and Scheduling Maintenance Projects
Handling specialities of maintenance projects is a highly challenging task. On the one hand the operations of the maintenance tasks are fixed, and can be described with network or process planning methods. On the other hand the realization sequence of maintenance tasks depends on the risks and reliabilities. Therefore, traditional project and process planning methods are not well suited to manage the maintenance tasks. In this paper a new multilevel planning method is introduced, where project constraints can be taken into account in determining the optimal maintenance project. Tasks which have to be realized can be ranked with our method based on their reliabilities or risk factors. The introduced procedures show how matrix-based methods can be applied for planning and scheduling the maintenance projects on the level of the whole system, the devices, the maintenance tasks and their operations.
