Age-Based Maintenance Scheduling with Multiple Maintenance Modes Concern

In practical production system, the equipment may shift randomly from working state to the failure state with age deterioration. As the effect of aging on the deterioration rate of most repairable equipment cannot be ignored, and preventive maintenance (PM) activities can only be able to restore part of the performance and corrective maintenance (CM) is performed after failure, efforts should be devoted to combination of PM and CM under age-based policies. This paper considers maintenance scheduling problem with multiple maintenance modes. The objective of this paper is to determine the proper maintenance sequences while minimizing the total cost under equipment age deterioration. This paper develops a model to solve the problem described and uses a yard crane maintenance case to discuss the impact of reliability range parameter.
