Research On The Optimization Of The Railway Freight Organization Based On Modern Logistics System

With the rapid development of the national economy,Logistics demand growing, the market economy improving, social division of labor specialized, customer demand personalized, the structure of transportation demand is gradually shifting. When rail transportation has not much interest of space in the field of conventional transportation of large amount commodities, so as to achieve sustainable development, it is necessary to optimize the organization of transportation, develop the railway freight logistics, carry out logistics services and expand its scope based on the perspective of modern logistics systems with taking into account the upstream and downstream enterprises of the supply chain. Then expand the cargo transportation market while carrying out express services for goods of high value to meet the demand on the timeliness.The paper firstly analyses the transportation process and the content of railway freight organization which is such a wide and sophisticated problem that the paper just studies the problems of freight transportation operation progresses and wagon flow organization; by analyzing the theory of logistics system, the demand on railway freight transportation that meets to modern logistics system is concluded. Thus the deficiency of the general way and the characteristics of the way based on modern logistics systems of railway freight transportation organization optimization are both analyzed; according to the analysis of characteristics of the rail freight transportation and logistic demand under new situation, the trend of rail freight transportation based on modern logistics system is concluded; then it improves the operation process at freight station; the paper introduces an inventory and transportation optimization model considering both the time and the cost to optimize the schemes for organizing wagon flow; Finally, combining with the actual circumstances, it discusses the measures on how the railway freight transfers to modern logistics.
