Study Of China’s Air Cargo Network Topology

With the rapid development of China’s economy,the rise of the e-commerce industry and the need for the growth of express delivery business,China’s air freight has been booming.But the problems followed,the number of cargo planes is not enough,freight network is not perfect and so on.The layout of air transport needs to consider the route network first,which determines the capacity allocation and operation scale of airlines,and is an important way to improve the overall strength of China’s air freight.Whether the layout of air freight network can achieve the optimal allocation of resources,the network topology is a key factor.The existing research on China’s air freight network is based on passenger transport network,carried out in the way of carrying cargo in the abdominal compartment,and there is little in-depth discussion on the freight network composed of all cargo aircraft.Therefore,it is of great significance to study the topology of China’s air cargo network.Based on this,the main research contents of this thesis are as follows :(1)The research status of China’s air cargo network is expounded,and it is found that the existing analysis of air cargo network is mostly based on passenger transport network.On this basis,the research on the structure of China’s air cargo network composed of all cargo aircraft is proposed.The basic concept of complex networks and the definition of some basic and required characteristic parameters are introduced,and the types of complex networks are summarized and classified.Collect the relevant data of China’s all-freight airline network,establish the all-freight airline subsidiary network and China’s all-freight airline network.(2)The general network structure and statistical properties of China’s freight aviation are analyzed,and the basic characteristics of the network are studied.Through the correlation analysis between network topology indicators and the further discussion on the network with the help of network centrality indicators,the hub node and development connection mode of the network are determined.Finally,Pearson r value is used to study the correlation of each centrality.(3)Based on the establishment of the sub-networks of various freight airlines in China,some network topology characteristics are selected to study the current situation of the sub-networks of various airlines.Through the analysis of node types and route uniqueness,the contribution and connection preference of each airline in the total network are compared.In order to better evaluate the network structure and enterprise situation of each airline,economic indicators are added to establish a comprehensive analysis model,and the network of each freight airline is studied.Get the rank of freight airlines in China.Then by resetting the weight of sensitivity analysis to determine the stage of development of China’s freight airlines,and the different stages of the development of the network of freight airlines related recommendations.
