Optimizing Train Platform Allocation in Busy Complex Passenger Stations with Fixed Track Utilization Scheme

The allocation of tracks in busy complex passenger station is generally based on Fixed track utilization scheme for the station, with the aim of enhancing operational efficiency and safety at the passenger station. This paper introduces a mixed-integer programming model designed specifically to address the train platforming problem in such stations. We propose constraints that align with the fixed track utilization scheme and aim to achieve balanced track usage objectives. Additionally, an enhanced genetic algorithm is presented, incorporating improved crossover and selection methods while maintaining compliance with the fixed track utilization scheme. Taking Wuchang Station as an example, the efficiency of the model and algorithm is verified, which operates under fixed track utilization scheme. Overall, this research provides efficient approaches for the TPP in busy complex passenger stations that adhere to fixed track utilization scheme.
