Research On Optimization Of China’s Air Cargo Network Based On Robustness

As an important link in the transportation industry,air cargo development can not only meet the increasing demand for air transportation,promote the upgrading of related industries,and form a scale effect,but also enhance the international competitiveness of my country’s civil aviation industry.With the rapid economic development,the demand for air cargo continues to increase,and the air cargo network has a wider and wider range of radiation.However,severe weather and emergencies such as thunderstorms and blizzards may cause the air cargo network to be interrupted.It is urgent for my country’s civil aviation industry to pay attention to the development of air cargo,enhance the robustness of the air cargo network,and improve my country’s air cargo network to improve air transportation.Comprehensive support capabilities.The thesis first summarizes the current research status at home and abroad,analyzes the development basis of my country’s air cargo and the current status of the air cargo network,and selects 79 airports with a cargo and mail throughput of more than 5,000 tons in 2019 to establish a connection matrix.The research sample of this article.Then use the relevant statistical indicators of complex network theory to carry out an empirical analysis on the structure of my country’s air cargo network.The analysis of statistical indicators shows that my country’s air cargo network is a small-world network.Many studies have shown that the degree value of the node airport is roughly positively correlated with airport cargo and mail throughput and passenger throughput.At the same time,the research shows that the central agglomeration of the sample network is relatively strong.On this basis,the robustness of my country’s air cargo network is simulated,and it is concluded that the robustness of China’s air cargo network under deliberate attacks is worse than that under random attacks.Finally,this thesis proposes corresponding network optimization countermeasures based on the development status of my country’s air cargo network and robustness simulation results.It mainly discusses and optimizes the robustness of my country’s air cargo network from three time periods to enhance the risk prevention awareness of hub airports,promote the construction of intelligent informatization and optimize the network structure for analysis and exploration in order to improve the robustness of my country’s air cargo network.The research in this thesis has very important theoretical significance for understanding my country’s air cargo network and improving the robustness of my country’s air cargo network.At the same time,it provides reference value for air cargo network layout and operation management.
