Research on Optimization of Train Operation Plan Based on Interconnection

This paper proposes a multi-objective programming model for the train operation plan in the context of cross-line operation between the subway and suburban railway. The model takes into account the travel costs of passengers and the income of both enterprises, while considering the impact of non-cross-line passenger flow. It aims to enhance operation efficiency, service level, and resource sharing. By determining the optimal allocation of trains and devising an efficient stop plan for cross-line trains, the model contributes to improved operational performance. Finally, a solution algorithm based on the weight coefficient method is designed and the model is validated using real operation data. The simulation results indicate that a reasonable quantity allocation of trains and stop plan for cross-line trains can effectively reduce passenger travel time and increase revenue for operating enterprises.
