The Study On Plan Of Coal Transportation Based On Sea-Rail Combined Transportation Mode

Coal is main energy in our country,its production and demand deployment is our country economic development,social production and people’s lives necessary protection.However,China’s coal production and consumption in the space on the dislocation distribution,leading to coal transport from west to east and north to south pattern.In order to solve the transportation cost in coal transportation,reduce the pressure of each line transportation and ensure the timely supply of coal demand,it is necessary to study the coal transportation problem under the seal-rail combined transport ation mode,so as to provide reference for the actual transportation work.Based on the actual situation of China’s coal transportation,this paper uses the theoretical methods of logistics,operational research and statistics to sort out the coal production and demand in China,and summarizes the transportation lines and transit ports,anduse quantitative methods to predict the future consumption of coal.Then the specific research and analysis on the optimization of coal transportation under the mode of sea-rail transportation is carried out.The specific contents are as follows.First of all,analyzes the main producing areas and consumption areas of coal in China,clarify the specific distribution of coal location,storage,consumption areas.analyzes the relationship between coal consumption and GDP,further explain the status quo of coal dislocation production and distribution in China.Secondly,it analyzes the transportation pattern of China from the railway system and the port transit system,express the main coal-bearing railway lines,the coal transport volume of lines,the port and city that connected by lines,coal transit port and arrival port and so on.This paper pointed out that coal north-south transportation is mainly carried out by sea-rail combined transportation mode,and analyzes the current situation of coal transportation and the future development trend.Finally,according to the actual situation and characteristics of the sea-rail combined transportation mode,the optimization model of transportation allocation is established,Choosing the Guangdong,Zhejiang and Shanghai provinces coal transport and ZN Group of coal transport as a case background,Then using Lingo to solve the model,obtained the sea-rail combined transportation plan of the coal respectively.
