To address the problem of widespread operational efficiency decline caused by delay propagation due to the saturation of the airway network,this paper first analyzes the effect of delay propagation and the related properties of community structure and then establishes a weighted aviation network community structure division model based on flight delay propagation and an optimization model of airport node weights based on the core idea of Dijkstra algorithm.Finally,12 airports and 18 waypoints are selected from the airspace under the jurisdiction of the Yunnan Air Traffic Control Branch as the research objects.Combined with the results of structure division and airport node weight optimi-zation,two new routes are added to obtain an optimized route network,thereby alleviating delay propa-gation and heavy traffic.
