考虑多方效益的高速铁路客运通道合理分工研究OA

In the daily train adjustment timetabling of railway corridor,it is particularly important whether the adjustment of the train operation plan can coordinate with the train working diagram.By adjusting the operation plan of passenger trains in the parallel corridor,comprehensively optimizing the train working diagram,and exploring the changes in the benefits of various investors,a more realistic adjustment plan can be obtained,which provides guidance for railway enterprises'decision-making in the adjustment of the train working diagram.Through building travel service network to describe the passenger travel time,with the minimum cost incurred on transport investors and passenger travel time as optimization objectives and the limitation of capacity and train arrival time as the constraint condition,the nonlinear integer programming model was constructed,thus enabling the construction of the train operation plan and the train working diagram collaborative optimization model,with commercial software to be called to solve the model.The corridor was used as a case to verify the validity of the model.The results obtained by this model can reasonably optimize the train operation plan in the corridor and effectively reduce the travel time of passengers.By quantifying the changes in the benefits of each railway investor before and after the adjustment,the results can provide a reference for railway investors to further optimize the operation plan.
