Embodiment Construction
[0036] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0037] Such as figure 1 As shown, the present invention calculates the departure delay and arrival delay of each flight by mining historical flight data, and corresponds each flight to the route information it uses. Then, the coordinate information of each airport and waypoint is collected, and the historical flight data is classified and grouped according to the time series and the airport of origin. The cumulative delay time and delay time of each airspace unit are counted, and the average delay time of each time period is matched with the coordinates of each airspace unit to establish a feature matrix. Finally, DBSCAN clustering is performed for each time period to ...
