- To fully leverage the advantages of sea-rail intermodal transport, the automation upgrade of
the railway center station (RCS) is essential for enabling seamless connectivity between the RCS
and the terminal via automated guided vehicles (AGVs). This transformation introduces complex
scheduling challenges for sea-rail intermodal automated container terminals (SRIACTs), including multi-directional container flows, coordination among diverse equipment, and AGV charging
requirements with battery management. To address these challenges, this paper investigates the
multi-equipment collaborative scheduling problem in SRIACTs with consideration of AGV charging. A mixed-integer programming model is formulated with sequencing, timing, and energy constraints, aiming to jointly minimize makespan and total charging time. To improve computational
efficiency in large-scale cases, an improved genetic algorithm based on a decomposition-iteration
framework is developed according to problem-specific features. Furthermore, to address operational uncertainties, a digital twin-based hybrid rescheduling framework is extended to enable
real-time monitoring, disturbance detection, and rapid response to AGV status and battery levels, thereby enhancing system resilience and scheduling flexibility. Extensive numerical experiments are conducted to validate the effectiveness of the proposed algorithm and rescheduling
framework. On this basis, comparative analyses are performed on bi-objective formulations and
the flexible charging strategy. Additionally, sensitivity analyses examine the impacts of key factors, including objective weights, charging thresholds, rescheduling thresholds, and the number
and layout of charging facilities. The findings provide valuable insights for terminal operators
in formulating integrated scheduling strategies, optimizing AGV charging plans, and scientifically deploying charging infrastructure during the RCS automation process, thereby promoting
sustainable and intelligent terminal operations.
