Analysis On The Evolutio Of Air Cargo-transport Network Of China

In the past decade,air cargo business in our country has achieved unprecedented progress with the combined action of economic growth,deregulation and increased competition.The healthy and rapid development of air cargo system plays a significant role in the development of China's transportation and economy.In this situation,it is very important to analyze the air cargo network in China.In this thesis,the main research work is as follows:In the past decade,air cargo business in our country has achieved unprecedented progress with the combined action of economic growth,deregulation and increased competition.The healthy and rapid development of air cargo system plays a significant role in the development of China's transportation and economy.In this situation,it is very important to analyze the air cargo network in China.In this thesis,the main research work is as follows:Analysis on the current situation and evolution of carrying rate of cargo aviation network in China.By statistically analysis the carrying rates of three observation years in our country,the routes with lower carrying rate are obtained and the reasons are analyzed.The results show that the carrying rate of cargo aviation network in China is generally low,especially for those routes connecting the hub cities and the southeastern coastal areas.Finally,the thesis puts forward some suggestions to adjust the network structure and improve the air cargo carrying rate.Analysis on the current situation and evolution of robustness of cargo aviation network in China.Under the strategy of random attack and intentional attack,this thesis makes simulated attacks on the air cargo network in three observation years in China,calculates the functional characteristics of the network after being attacked,and analyzes the robustness of cargo aviation network in China and the evolution of robustness in the past decade.The results show that the network is more robust to the nodes under random failure than that under intentional attack,and the robustness of the network under intentional simulated attack has not improved compared with ten years ago.Finally,this thesis puts forward some suggestions to strengthen the functional maintenance and the defense of aviation network.
