Dynamic maintenance policy development for railway rolling stock

• PurposeThis paper proposes an approach for the development of a dynamic maintenance policy for the railway rolling stock system considering the dynamic characteristics of the system, the operation environment, and the maintenance process. The proposed approach can also be applied to other similar complex technical systems.Design/methodology/approachThis study explores the state-of-the-art in dynamic maintenance policy development for rolling stock to identify research gap. The proposed approach is demonstrated through a case study on dynamic maintenance policy development for rolling stock maintenance support planning, emphasizing constant assessment and improvement in the maintenance policy.FindingsThis study emphasises on the need for an effective, efficient, and dynamic maintenance policy that adapts to evolving system requirements such as organizational contexts, technological advancements, and regulatory requirements.This study finds that there are specific dynamic characteristics in each step of the maintenance policy development process. These dynamic characteristics are dependent on the changes in system requirements, the environment and in the maintenance process. The proposed approach for dynamic maintenance policy development provides a framework for the identification of these dynamic characteristics for different complex technical systems operating in a specific context.OriginalityDespite the significant impact of rolling stock maintenance on railway system availability, research in this area is limited. The proposed approach for maintenance policy development for rolling stock integrates adaptability and responsiveness to dynamic factors in the maintenance process and the system requirements. Thus, the proposed approach provides a guide for industry professionals and directions for future research in dynamic maintenance policy development for other similar complex technical systems.
