Research On Optimization Of China-Europe Interclass Logistics Transportation Network

In recent years,China-EU bilateral trade has achieved rapid development,and China has become the EU's largest source of import and the second largest export destination.Frequent trade exchanges have led to a surge in logistics demand for Sino-European merchandise trade,which has also brought new challenges to China's product export operation model.The Sino-European class has opened up a railway corridor between China and Europe,which has greatly improved the problem of slow and unstable traditional European shipping.This progress has opened up a new prelude for Chinese railways to enter the world's railway freight transport.In just a few years,the “One Belt,One Road” main strategy has continuously stimulated the trade needs between China and the countries along the “Belt and Road”.And the range of radiation is constantly increasing.However,regardless of the operation organization,operation mode or coordination mechanism,there are many problems in the direct transportation mode of the CEIBS class.For example,the normalization rate of the trains is low,the lines are repeated,the return rate is high,and the supply of goods in different cities is competitive.It has affected the balanced development of the China-European class.Therefore,in order to improve the shortcomings of China-European trains,it is necessary to follow the economic layout,port distribution and international corridor construction in China,to use several cities as hubs,to innovate the transportation mode of Central Europe,and to construct the Central European trains.International logistics and transportation network,“shared trains,joint transport” across the country,fully loaded through Yanbian land port nodes and European hub cities,and finally delivered to European destination cities,achieving “grouping,scattered transit” and reducing operating costs To avoid waste of transportation capacity and ensure the high-frequency normal operation of the transportation train.In Chapter 1,the article first combines the research of the Sino-European train and logistics transportation network to optimize practical problems,based on the research status at home and abroad,the study of the operation mode and operation management of the China-Europe train,the integration and optimization of the China-European transportation network,and the inheritance.The algorithm studies the relevant literature in the modeling and application of logistics transportation network,analyzes the shortcomings in the current research,and further proposes the research questions,expounds the research content and research plan of this paper.Then,in Chapter 2,from the perspective of the mode of operation,operation mechanism,supply organization and transportation coordination of China-Europe train,the existing operational advantages and existing problems of China-Europe trains are pointed out.In Chapter 3,this paper introduces the optimization basis of the Sino-European international logistics transportation network,and builds the Sino-European axis-spoke international logistics transportation network system with the actual situation,and proposes the direction of optimization problems.Then,in Chapter 4,the mathematical modelling method is used to establish an optimization model for the international logistics transportation network of the China-European class.In Chapter 5,according to the optimization model proposed in Chapter 4,the genetic algorithm is used to take the actual situation of the mediumEuropean carriage train as an example,and the results of the network optimization scheme of location selection and path selection are obtained.In Chapter 6,combined with the analysis results,the paper proposes to promote the international logistics transportation network to better serve the development of China-European trains,and to improve and optimize from the aspects of transportation mode reform,transportation resource integration,operation process optimization,and business coordination and operation.Finally,in Chapter 7,the conclusions of this paper are listed,pointing out the shortcomings in the research and analyzing the future research directions.The research shows that compared with the Central European trains,the SinoEuropean axis-spoke international logistics transportation network organization model has higher reliability,which is manifested in two aspects: First,the China-European classarrival international The organization mode of logistics transportation network and the direct-to-point direct transportation mode of China-Europe alignment are not much different.The second is that the Sino-European axis-coordinated international logistics transportation network organization model is more in line with the trade demand among the countries along the “Belt and Road” and Central Europe.The development of the trains,while the Central European trains are not a bit of a direct transport mode can not actively respond to such changes,there will be instability in the results of the operation.
