Abstract:

In order to explore the generation, dissemination and control process of flight operation risk, the flight operation data of North China region is counted, with a total of 76 risk nodes. Then, the partial rank correlation coefficient is used to construct the risk network, and the community module detection and triangular maximum filtering method are used to verify the applicability of the network. Furthermore, a SEIR model for flight operation risk analysis is proposed. According to the results of dynamic propagation, the key nodes in network propagation are located by clustering. Finally, two kinds of control schemes, pre prevention and tactical disposal, are adopted. The results show that the infection peak can be reduced by 18.44% when only 5 nodes are controlled, and the peak time can be postponed by two cycles, and the average infection times of important control nodes such as take-off and landing nodes can be reduced by 11.74%. The inhibition effect of this scheme was superior in three aspects: infection peak, infection cycle and infection of important nodes. The above results confirm that the proposed scheme can be effectively used for flight operation risk analysis.

Key words: flight operation risk, complex network, partial rank correlation coefficient, improved susceptible-infected-exposed-recovered (SEIR) model, network key nodes
