Study On The Optimization Of The Train Development Plan Forrailway Express Cargo Trains

With the rapid rise of e-commerce and high-tech products during the transition period,people’s consumption characteristics have also shifted from imitative styles to the individualization and randomization,and high added value products represented by electronic products,medicine,equipment and consumer goods dominate the transportation market.In order to increase the competitiveness of the railway in the transportation market,increase the market share of the transportation,and adapt to changes in transportation demand,the railway company further intensified its freight reform in 2014,and fully launched express trains for goods,in fact,the operation of trains directly affects the service level and economic benefits of express freight,so it is of great practical significance to carry out optimization research on the program of express freight.In this context,this thesis fully understands the actual operation of the current express freight through real-time research.Taking the Sanjin Express Freight as an example,the optimization study of its program is carried out.The research content is as follows:(1)On the basis of summarizing the status quo of the development of domestic and foreign railway express freight train transport organizations,this thesis analyzes the outstanding problems in the current organization of express freight in various railway bureaus in China.Combining with the characteristics of China’s express freight organization,the thesis clarifies the main contents of the train program design,including the principles and the influencing factors of the train program design,and it proposes the problems existing in the current program and the necessity of optimization.(2)This thesis analyzes the main target objects and types of goods of express freight transport,it expounds the main methods and steps of qualitative and quantitative forecasting of express freight,then designs the forecasting model of freight volume,and carries out the forecasting of the output volume.Finally,the OD volume is forecasted using the double-constrained gravity model,and an optimization model for the train program is constructed to optimize the logarithm and stop plan of the train program.(3)The thesis takes the Sanjin Express freight of the Taiyuan Railway Bureau as an example,on the basis of the research data of the “Jinbei Express Freight Line” and the “Jinnan Express Freight Line”,this thesis forecasts the freight volume of the major cities and completes case analysis of the optimization design of the express train program.
