摘要：

The stage plan of marshalling station will be affected by the fluctuation of railcar flow in the process of implementation. A way to measure the coupling relationship between the stage plan and the dynamic railcar flow and to control the railcar flow in a certain range is very important for the dispatching operation of marshalling stations. The allowable variation ranges of train delay time, the break-up operation time and marshalling operation time were analyzed under the condition that the implementation resources of the station stage plan had been determined. Then the method of calculating the coupling degree between the station stage plan and the dynamic railcar flow was given. An optimization model was established to reduce the impact on the overall operation of a station when the change of railcar flow was beyond the allowable range, and railcar sources were adjusted without changing the original disassembling and marshalling sequence. The example shows that the station stage plan is susceptible to the factors such as the arrival time of train, the difference between the actual arrival of train and the expected arrival of train, and the fluctuation range of break-up operation time and marshalling operation time. The coupling degree between the stage plan and the dynamic railcar flow can be improved to a certain extent by reasonable railcar flow assignment. © 2020, Department of Journal of the China Railway Society.
