High-speed Rail Express Transportation Product Design Research

With the rapid development of people's material life,the railway enterprises' slowpaced transportation products have been unable to keep up with the people's increasingly accelerated pace of life.Express delivery has become the main way for people to transport goods.According to statistics,in 2019,the peak volume of express delivery will reach 535 million pieces per day.As a new product of railway freight industry,high-speed rail express has been recognized by most users.But in terms of the current development form,passenger transport still occupies most of the high-speed rail line resources,which greatly limits the future development of high-speed rail express.How to use the least line resources to complete the most freight transportation is the development difficulty of the express industry.Based on this situation,this paper analyzes the transportation situation of highspeed rail express and the current organization mode of high-speed rail express,and studies the organization scheme optimization of high-speed rail express.The main contents of this paper include:(1)This paper analyzes the development and research status of domestic and foreign high-speed rail express,analyzes the characteristics of high-speed rail express by using swot-ahp analysis method,and finally determines the future development direction of high-speed rail express according to the market positioning of high-speed rail express.(2)This paper summarizes the domestic and foreign data,combined with the definition of high-speed rail express,carries on the classification statistics to the highspeed rail goods.According to the data analysis of different high-speed rail express products(that day,the next morning,the next day,the next day,etc.),analyze the characteristics of different express products,and study the transportation capacity of different means of delivery.Finally,combined with China's national conditions,the national high-speed rail line resources and infrastructure are analyzed to lay a theoretical foundation for the following study of transportation organization scheme.(3)According to the express volume and basic economic data of each province,the express volume of different od is calculated by combining the principal component analysis,regression prediction model and double constraint gravity model.Finally,the express volume of high-speed rail between od is calculated by the express share rate of high-speed rail obtained by logit model.(4)According to the principle of train flow organization in railway industry and the situation of our country,the basic principle of express train organization is put forward.This paper takes the maximum revenue of railway enterprises and the minimum line resources occupied by express trains as the objective function,takes the train load and the infrastructure configuration of high-speed rail trains as the constraints,constructs the transportation model of high-speed rail express products,and uses the artificial fish swarm algorithm for programming calculation.(5)This paper analyzes the data of Beijing Shanghai high-speed rail,selects the cities with high express volume on Beijing Shanghai line as the prediction point,forecasts the express volume between OD,and then puts the express volume data into the model to solve,obtains the express operation plan of high-speed rail,and analyzes the rationality of the plan.This paper optimizes the operation process of express delivery at both ends,reduces the online operation time at both ends,improves the coordination between each step,and further enhances the freight market competitiveness of high-speed rail express.
