Research On Collection And Distribution Technology Of Railway Freight Transportation Corridor

With the rapid development of China’s economy and science technology, the acceleration exchange rate of the elements of production, resources, investment and trade etc., the freight traffic face a vast room for the growth, and freight market is coming to enter a period of rapid increase, so, it is a urgent need to improve the integrated transport market that accelerate the construction and improve the transport channel to take on the growing cargo transport demand.At present, driven by transport sustainable development, railway freight transportation shows the trend of overloaded, shortcut and logistics, thus, such as the Daqin channel, the Guangzhou-Shenzhen-channel Jing guang channel with the specific nature of the some freight corridors came into being. either overloaded channel or fast channel, are required to match production operations within the system and external coordination, the railway sector cannot just be satisfied with the functions of the "transport", but rather conduct integration organization and coordinate on the upstream supply of transport channel and downstream of the cargo flow, implements transport organizations mode of collection and distribution integration.This article relies on the mature port transport theoretical knowledge, to study the rail freight corridors collection and distribution technology with a wide range of instructive. The paper describes the definition of the rail freight corridors, analyzes the current research status of the railway corridor collection and distribution system at home and abroad; illustrates the connotation of the railway corridor collection and distribution of content and integration; improves the Huff model the second time draw on the theories of economics in the business district, which can make it applies to computing the set of sparse subsystem attractive range of fixed production resources lopsided configuration ideas on this basis. Then, on the basis of traffic forecasts, the paper focuses on information systems conduction of the collection and distribution integration and integrated cargo operations process reengineering, builds the Petri net model of the collection and distribution and integrated freight forwarding processes. Finally, combined with the Daqin transport channel situation, the paper proposes collection and distribution optimization tips to enhance the Datong-Qinhuangdao line transport volume. The conclusions of this paper contribute to the formation of rail freight corridors in the broadest sense of the collection and distribution theory, and transport efficiency of rail freight corridors.
