Study On Transport Organization Of Container Regular Train Based On The Cooperation With Express Enterprises

At present,China is in the important stage of the railway enterprise market-oriented reform and freight reform.Containerization transportation is the development trend of modern railway transportation,and it is also an important direction of railway freight reform in China.Meanwhile,the rapid development of the express industry in recent years has also stimulated the continuous growth of the transportation industry.It is the inevitable choice for railway freight to grab the express freight market.Therefore,this paper puts forward the idea of using railway container liner to transport express goods on the basis of the cooperation between railway departments and express logistics enterprises.The existing railway container transport in China is at a low level both in terms of equipment and transportation organization.However,the railway container has obvious transportation advantages and great transportation potential,so it is feasible to carry out freight transportation of container express.Based on the existing transportation conditions and the expected realization,this paper analyzes and researches the related transportation organization problems.First of all,the paper summarizes the developed countries experience of railway container transport.And through the discussion of its own advantages of container transport,analysis feasibility of railway container carriage of express goods on the basis of analysis of the present situation and existing problems in China railway express product and sum up the experience of railway express cargo transport development.Secondly,the paper analyzes the key problems of freight transportation organization of railway container express.Summarize and analysis the main content of railway container transport,including "passenger transport mode" transport organization mode,container "passengers" management,container regular trains to organizational form,and container transportation network layout and so on.This paper analyzes and presents the container "LCL" mode for express goods,and discusses the new type of box design and loading mode.Analysis of container trains transport related equipment configuration issues,including container terminal handling equipment configuration,hybrid locomotive traction and vehicle type selection,etc.,and container transportation information system is introduced in this paper.According to the cooperation needs of the express logistics enterprises,the paper discusses the issues related to the setting and siting of the distribution center,the transportation and operation network of container express goods and the distribution of containers.Then,the paper completes the optimization of the plan of "passenger transport" of the express container liner.The paper describes the problem of development of the plan,establishes the important principle of market orientation,complementarity and gradual progress,and establishes the process.Analysis operation scheme of main influencing factors,including transport demand and traffic prediction,trains marshalling bought,node,stop time,travel time consumption and railway corporate earnings,etc.Considering the timeliness of express cargo transportation,the optimization model of"passenger transport" operation plan of container liner is set up with the minimum hourly consumption of road network boxes.Algorithm solving process to carry on the design of the model via split container flow line network problem can be converted to problems,and to determine the number of train operation,selection of genetic algorithm for the final solution for train stops.Finally,the paper completes the case analysis of the express container line.According to the results of the survey,the data is selected and the data is prepared,and the daily OD box flow rate of the express goods of the six container central stations or special stations on the Beijing-Guangzhou line is selected as the basic data.Based on the calculation of the parameters and the number of trains,the genetic algorithm is used to solve the train stop station scheme,and the scheme evaluation is carried out.Considering the actual transportation needs of the car bottom and the box body circulation,the adjustment of the train under the condition of pair operation is carried out.According to the Courier companies and railway container station operation time of each link,to express container trains the specific operation time and scheme design,including locomotive and cross road,column of flight check work locations,delivery in time and so on,and get the train car circulation use.
