Working Diagram Optimization Method of Beijing-Shanghai High Speed Railway Based on Capacity Utilization between Sections and Terminal Stations
摘要
Abstract
One difficulty in train working diagram scheduling of the Beijing-Shanghai High Speed Railway is how to coordinate the utilization of section and station resources and improve the overall capacity of the railway line.To support the working diagram optimization of the dense high speed railway mainline,according to the current train periodic operation structure of Beijing-Shanghai High Speed Railway,this paper added the constraints of train connection time and switch safety intervals at the terminal stations based on the traditional working diagram scheduling model.Meanwhile,a mathematical model of train working diagram scheduling for coordinated utilization of the capacity of the sections and terminal stations was built to coordinate the optimization of train stop schemes,arrival and departure time and terminal station utilization,and realize the overall utilization of section and terminal station resources.Beijing-Shanghai High Speed Railway and Beijing South Railway Station were taken as examples to verify the feasibility of the model.Compared with the actual diagram,the optimized one has sound section capacity and short connection time.The research results lay a theoretical foundation for improving the scheduling quality of train working diagrams of Beijing-Shanghai High Speed Railway.关键词
