Research Of The Optimization In Coal Logisticsnetwork Of A Group

China has abundant coal resources,which are the most important energy resources.However,the distribution of coal resources is uneven.The regional distribution and supply and demand structure of coal resources cause the transportation pattern of coal from north to South and from west to east.Group A is an energy logistics group in the Pearl River Delta.The market share of Group A of coal sales in the Pearl River Delta has remained the first for many years.Affected by the slowdown of economic growth and the policy of "coal removal" in the Pearl River Delta,the coal operation of Group A is facing great difficulties.How to optimize the coal logistics network,reduce the total cost of coal and enhance the market competitiveness is of great significance to the sustainable development of Group A.This paper introduces the status quo of coal logistics network research at home and abroad,analyses the status quo of coal business purchase,transportation,sales and competitive advantages and disadvantages of Group A,analyses the coal logistics network of Group A and its existing problems and cost composition,constructs the optimization model of Group A coal logistics network with the lowest cost as the goal,and uses this model and related data to the coal logistics network of Group A.The network carries out optimization solution,carries on the optimization analysis to the solution result,proposes the implementation safeguard condition and the countermeasure measure.According to the optimization model of coal logistics network of Group A,the total coal cost of Group A has been greatly reduced after the optimization by solving the linear programming problem.Optimizing and increasing the end nodes of coal purchasing in Group A is the most effective way to reduce the total cost of coal.Optimizing the transshipment ports can reduce the cost of coal handling in Group A,and optimize the distribution routes and the impact of transshipment on the cost of coal transportation.Overall,through the optimization of coal logistics network of Group A,the total cost of coal can be greatly reduced,and the economic benefits and market competitiveness of Group A can be effectively improved.
