To analyze the occurrence law of flight delay,a visual analysis method based on mathematical model combined with multi-view collaboration was proposed.The transmission model of SEIR infectious disease was adjusted.The flight delay propa-gation model was established to analyze the transmission characteristics of delay,and on this basis,the frequent subgraph mining algorithm was used to extract the delay frequent mode.A map network diagram based on midpoint segmentation,matrix heat map and time series diagram were designed to analyze the temporal and spatial distribution characteristics of delay.The VA-FDC system was designed for method validation.The results show that VA-FDC can effectively analyze the spatial and temporal dis-tribution characteristics of flight delays,and accurately describe the delay propagation characteristics according to the flight delay propagation model,so as to provide reference for the formulation of effective measures by relevant departments.
