Multi-plan Collaborative Rescheduling of High-speed Train Operation Considering the Utilization of Rolling Stock and Arrival and Departure Tracks
With the rapid development of high-speed railways in China,the"eight vertical and eight horizontal"high-speed railway network has become denser,presenting typical characteristics such as complex operating environ-ments,high train densities,and long-distance cross-line operations.Once facing sudden events as strong winds,red light bands,foreign objects on overhand lines and equipment failures,trains will deviate from the operating plan,which in turn affects the departure line operation and electric multiple units(EMUs)turnover plan.Ensuring the feasibility of EMUs and departure line operations while adjusting timetable is crucial to improving the efficiency of train operation adjustments.To address departure line operations conflicts and EMU connection plans failure un-der the scenario of bidirectional interruptions between sections,strategies as canceling trains,changing train depar-ture times,switching departure lines,backup EMU connections are employed to adjust timetable,EMUs,and de-parture line operation plans.A train operation coordination adjustment model considering EMU connections and departure line operations is established based on event-activity network,a two-stage solving method is designed to solve the model.The model and method are validated using actual data from Beijing-Tianjin intercity railway,the results show that compared to"first come,first served(FCFS)"strategy,multi-plan coordination adjustment meth-od can effectively reduce train delay time.Compared with overall solving method,the two-stage solving method can ensure the model solution quality and effectively improve the model solving efficiency.
