基于加权圈比的飞行冲突关键节点识别OA

In view of the problems that the risks of flight conflicts are sharpening and the difficulties are increas-ing in identifying a critical conflicted aircraft against a background of surging air transport demand,this paper pro-poses a key node identification method based on complex networks and weighted cycle ratio(WCR).The method is to establish a flight conflict network by taking the conflicting aircraft as a node and the conflict relationship as a connecting edge based on cycle ratio(CR),fusing edge weight information,proposing the concept of weighted cycle ratio in combination with node strength(NS)to form adjustable mixed indicator(MI)used to identify the key in the flight network.In order to validate the effectiveness of critical nodes,node deletion experiments are conducted based on Val-based ranking.Evaluation is performed by calculating the area S enclosed by the network efficiency change curve and the coordinate axes.The results show that the average area S for the proposed method is only 27.6,approximately 7.1％,13.2％,11.3％,and 19.1％lower than those for NS,BC,WCR,and CR.The method ef-fectively identifies critical conflict nodes,supporting targeted regulatory decisions to reduce network complexity and global conflict risks.
