Abstract

High-level maintenance is one of the key practices to ensure the safe operation of high-speed trains (HSTs). However, it is usually scheduled manually, and there has been a lack of systematic study on how to optimize maintenance scheduling considering a dynamic time interval. This article discusses the state-of-the-art high-level maintenance scheduling models of HSTs. The one-time maintenance scheduling problem, where the maintenance action occurs at most once in the planning horizon, is a key issue for HSTs’ high-level maintenance. We construct a more efficient mathematical model and propose an exact solution for the one-time scheduling model (OSM). However, HSTs might be maintained several times within the planning horizon to achieve a more favorable performance in real-world practice. Therefore, we extend the OSM to the periodic scheduling model (PSM), which aims to accommodate several maintenance actions and could be valuable to obtain a global optimal plan. Both models are mixed 0–1 linear integer models and can be solved by commercial solvers. The effectiveness and comparisons of the proposed models are illustrated by a real-case study using the maintenance records of 100 HSTs in China. The results can serve as the basis for the HSTs’ high-level maintenance scheduling under either a periodic case or a one-time case. © 2023 IEEE
