Reasonable shunting operation plans can greatly improve the operation efficiency and maintenance capacity of the electric multiple unit (EMU) depots. On the premise of determinate layout of tracks and each function sections, the effect of EMU marshalling status and occupation on the shunting operartion plan is analyzed. With the objective of reducing track occupancy times during shunting operations, and taking EMU operation time, shunting operation sequence and track type as constraints, an optimization model for shunting operation plan considering train position occupancy is established, a simulated annealing algorithm based on the feasible route generation and the priority exchange for shunting operations is proposed. Finally, an example of shunting operation plan at the EMU depot is used to verify the effectiveness of the model and algorithm. The results show that the proposed approach yields a shunting operation plan in a short time and with a small number of track occupancy. The number of EMU transfers is reduced to 34, and 80% of the EMUs have realized the quick storage operation.
