Study On The Logistics Network Planning Of Coal Chemical Industry Products In Yulin

Modern coal chemical industry is a coal processing and transformation industry with coal as the main raw material and production of chemical products as the main goal.It is an important means to realize the two functions of coal energy and resources.It is an important way to ensure the energy security of our country,realize the clean and efficient processing and utilization of coal,and promote the adjustment of industrial structure and the development of local economy and society.Since the 13 th Five-Year Plan,China has accelerated the pace of energy structure adjustment,and regards deep coal processing as an important energy and chemical industry.Yulin City responded positively to the call to transform from a resource-based city to develop new kinetic energy,using the advantage of rich coal resources to vigorously develop the coal chemical industry,coal olefins,coal quality utilization,Coal to ethylene glycol as a leading industrial development.Yulin coal chemical products will drive the development of manufacturing industry,logistics storage industry,transportation industry and other industries in Shaanxi Province,and even affect the supply and demand of chemical products in China and the market competition pattern.Therefore,reasonable selection of Yulin coal chemical products market,scientific layout of logistics network is the focus of this paper.This paper first selects the target market of Yulin coal chemical products.Based on the analysis of the supply and demand status of these products,Pearson correlation coefficient is used to verify the close degree of the product and downstream industry.According to the development law of ethylene glycol,polyester,synthetic resin,engineering plastics,caustic soda and urea,the demand of these products in 2020-2025 is predicted by linear regression and time series combination prediction.Then we introduce the market choice model,from the market demand potential and market entry barrier two dimensions to me The target market of coal chemical products in Yulin is determined to be four regions: North,Central,East and South China..Next,this paper analyzes the location of logistics network nodes in four regions: North,Central,East and South China.First,after analogical analysis,the number of nodes is determined and 20 alternative nodes are selected.Three different node location schemes aredesigned for the different products that are focused on development in each regional market.And from the market demand potential,cargo transport scale,transport costs four aspects of the alternative node ranking calculation.Finally choose Beijing,Shanghai,Wuhan,Guangzhou as Yulin coal chemical products transport logistics network node city.Finally,this paper analyzes the basic pattern of China’s railway trunk lines,the transportation channels in North,Central,East and South China,and the main ports in China.On this basis,based on the integrated transportation network,the transportation mileage,transportation cost and transportation time of coal chemical products in Yulin are analyzed,and the transportation cost of coal chemical products from Yulin to each node city is calculated..
