Robustness analysis of multi-layer dynamic aviation network based on accessibility
In order to more accurately describe the aviation network and analyze its robustness,a multi-layer dynamic aviation network model was proposed,which used the same origin airport and its departure flights as sub network layers and dynamical-ly changed with departure time.For the multi-layer dynamic aviation network in China(excluding Hong Kong,Macao,and Taiwan),the accessibility,degree centrality and weighted intermediate centrality were taken as the node characteristic inde-xes,and the network efficiency was taken as the network performance measurement index,then the robustness of the network was analyzed from the two strategies of random attack and deliberate attack.The results show that the robustness of the avia-tion network in domestic(excluding Hong Kong,Macao,and Taiwan)is mainly provided by 20%of the airports,and the ro-bustness is different in different time periods.During the 2023 summer and autumn shipping season,the robustness is good from 7∶00 to 20∶00,and poor from 4∶00 to 7∶00 and 20∶00~24∶00.The accessibility index is more accurate than the degree centrality and weighted intermediate centrality index in measuring the importance of airport nodes in the aviation network.The results have reference significance for ensuring the safety of aviation transportation network.
