Research on Integrated Compilation of Intercity Railway Train Operation Plan and Working Diagram
With the improvement of the intercity railway transportation network and the growth of passenger flows,the integrated compilation of train operation plan and working diagram can give full play to the equipment capacity along the line and at the station and improve the efficiency and quality of train transportation plan compilation.In this paper,to minimize passenger travel cost and train operation cost and maximize passenger demand and train matching degree,a multi-objective optimization model for integrated compilation was constructed and solved by an improved immune cloning algorithm.In view of the difficulty in solving the integrated model,a train routing optimization model was constructed to determine the train routing in each period and the train operation frequency on each route,and the initial solution of the integrated model was obtained to improve the solving efficiency of the algorithm.By taking the Changsha-Zhuzhou-Xiangtan Intercity Railway as an example,the results show that compared with the original operation scheme,the total cost of passenger travel is saved by 7.7%,and the railway operation cost is saved by 10.5%.The total operation time of trains is reduced by 0.6 hours.During the peak hours of passenger flow,the departure interval of trains from Changsha to Zhuzhou and from Changsha to Xiangtan is within 12 min.The science and rationality of the model are verified,which provides a theoretical basis for realizing the cooperative optimization of intercity railway transportation organization.
