Research On Optimization And Evaluation Of Division Of Labor Scheme Of High-speed Railway Hub Station

Under the background of the blistering development of China’s high-speed railway,high-speed railway hubs have introduced more routes in more directions,which brings more burdens to the organization work of the hubs.So for railway hub of division of labor,equipment,station within and improve the capacity coordination using the research methods,can more effectively balanced use of all kinds of resources,play to the ability of lines and stations,promotes the entire high-speed rail hub operation ability,provide better theory basis for railway policy makers to actual operations decisions hub division of Labour.This paper first introduces the basic theoretical knowledge of capacity coordination of high-speed railway hubs,then introduces the concept of "meter-shape" high-speed railway passenger hubs according to relevant literature,and further analyzes the functions and characteristics of high-speed railway passenger hubs as well as the division of labor mode.Summarized the calculation method of the capacity index of station,line and bullet train operation station of high-speed railway passenger terminal.Based on the relevant content,this paper constructs the high-speed railway passenger transport hub network,and puts forward the modeling idea under the research background of vehicle flow path.By referring to the multi-commodity flow model and considering the line,station capacity and other constraints,the capacity coordination model of high-speed railway hubs is established with the minimum operating cost of OD traffic flow at high-speed railway passenger hubs.Papers in chongqing high-speed rail hub for the actual cases,combined with longterm plans for the development of high-speed rail in chongqing area files,will forward within the hub station index parameters and OD traffic as a data base,the high-speed rail hub station capacity coordination model to deal with the related data,on the basis of solving the optimized high-speed rail hub of chongqing vision of OD traffic flow of each station division of labor.To testify the effectiveness of the optimized scheme of the model,the article analyzes the criteria of the evaluation index system after achieving the optimized scheme of the division of labor at the hub stations,and determines the evaluation indexes from multiple aspects based on the characteristics of the division of labor mode at the high-speed railway hub stations.At the same time,a variety of evaluation methods are introduced,and TOPSIS is chosen as the evaluation method according to the characteristics of the evaluation objects.Finally,TOPSIS evaluation model was used to evaluate the division of labor before and after optimization,to verify the effectiveness of the solution scheme,and combined with the actual situation,relevant suggestions were put forward.
