| Abstract | In order to meet the requirements of safety, energy conservation, punctuality, comfort and other indicators in the operation process of train ATO, a multi-objective optimization strategy based on improved Grey Wolf Optimizer (GWO) algorithm was proposed. Firstly, based on the train operation control strategy and dynamic equations, an evaluation function for performance indicators such as energy consumption, punctuality, comfort, and parking error of train ATO was constructed, and a multi-objective optimization mathematical model for the train was established; Then, based on the principles and drawbacks of the GWO algorithm, the initialization and position update methods were improved, enhancing the optimization ability of the GWO algorithm. The improved GWO algorithm was validated through testing functions to effectively compensate for the shortcomings of the GWO algorithm; Finally, the improved GWO algorithm was applied to multi-objective optimization of train ATO, and simulation experiments showed that the energy consumption, actual running time, comfort value, and parking error of train operation were significantly improved, verifying the effectiveness of this strategy. |
