Optimizing Train-Platforming Plans at Arrival-Departure Tracks of High-speed Railway Stations

Abstract

Efficient train platforming plans at high-speed railway stations are important for the station work organization. By defining four types of train technical operation chains and their corresponding occupation times of arrival-departure tracks, this paper proposes a multi-objective optimization model to simultaneously optimize the organized and balance use of station tracks. Based on dispatching principles, train movement constraints are constructed to avoid potential conflicts at congested high-speed railway stations. The multi-objective planning model is transformed into a single object model through min-max method and finally solved by The General Algebraic Modeling System (GAMS). The proposed method is tested in Xiong'an Station to generate track operation plans from 6:00am to 9:00am.
