An Energy-Efficient Optimal Operation Control Strategy for High-Speed Trains via a Symmetric Alternating Direction Method of Multipliers

Train operation control is of great importance in reducing train energy consumption and improving railway efficiency. This paper investigates the design optimal inputs for multiple trains on a single line with several stations. Firstly, distributed problem formulated to reduce improve punctuality trains. Then, we propose an efficient algorithm based framework symmetric alternating direction method multipliers solve this optimization problem. Finally, numerical simulations show that can obtain sequence fewer iterative steps compared multiplier method, thus illustrating effectiveness algorithm.
