The Identification Of Closed Loop In The Railway Less-than-carload Freight Transportation

With the rapid development of China's national economy, people's living standard is increasing day by day. The demand for transport of goods is no longer limited to the coal and other commodities, and high added value of less-than-carload transport demand is rising. Competition among the railway, highway, aviation and other transportation modes is increasingly fierce. In this situation, the demand of the railway to improve the market competitiveness and the market share is growing. So, less-than-carload freight transportation will undoubtedly become a new growth point. However, the defects of organization and transport organization of less-than-carload freight in railway has led to unfavorable situation of low input high output, high occupation of manpower and Imaterial resource, multi operation link and high accident rate, etc.Here, based on the background of railway cargo transportation, through the research of the less-than-carload freight flow, closed loop is identified. On the one hand, it can improve the less-than-carload transportation level, promote the reform of railway freight organization, and improve the competitiveness of the railway in the transportation market.On the other hand, it can also provide the basis for transportation production plan and organization method of the railway less-than-carload freight transportation. Those are all great benefits to the whole railway freight transport.Firstly, through literature research and market research, combined with the current situation of the market, the meaning of railway less-than-carload freight which with the characteristics of "high value-added, small volume, multi batch" has been revealed.Discussed the freight LTL freight railway closed loop connotation and analyses its significance by analyzing the market situation and the current railway transport organization. After that, this paper introduced the related technology of data mining algorithm, and chooses the Apriori algorithm as the research method.Then, by discussing the method of identification of closed loop in railway less-than-carload freight transportation, the identification model of closed loop was constructed. By changing the way of database mapping and optimizing the connection step,the defects of the Apriori algorithm such as frequent scanning of database and the complexity of candidate itemsets was improved based on reality.Finally, according to the assumption of the model, the data were preprocessed, and the correctness of the method was proved by an example. The practical significance of the results was discussed.
