Research On Optimization Design Of Air Transport Network Of Express Enterprises In China

With the rapid development of China's express and the raising the level of economic development, gradually expand the scope of express delivery. Currently, the scope of express delivery has not limited the traditional mail and parcel, more and more high-value items,important documents and so on, which have become business scope of express delivery. Since the economic value of express product, people's demand for the timeless and safety of express are increasing. They would rather pay some cost to choose a better express company in timeless and safety. Using passenger aircraft bellyhold to transport mail have been far below the needs of the customer. Therefore, China's private express giants began to lease and purchase all-cargo aircraft, they set up own air cargo company, and gradually transform to the air express companies. Air transport network is the basis of airline operations, air cargo companies of express also need to design a reasonable air transportation network to take advantage of cargo resources.The paper overview express and air express, and analysis of development and prospects of China's express delivery. Showing the dominance of air express enterprise. Resolving based on hub-and-spoke network for express delivery companies the choice of air transport and air transport network construction problem. Hub choice use P-hub choice model, the solution adopt tabu search algorithm. Air transport network construction use multi-attribute decision making, it achieve airline network construction to divide the area by the hub and the combination of air transport network and ground transportation network. Finally, the paper specific a example of SF express for empirical, which verify feasibility and rationality of the research methods.The paper includes 14 figures,10 tables and 53 references.
