Flight Classification Method Based on Unit Time Delay Cost

Traditional flight classification methods are usually based on the geometry of the aircraft or the size of the wake of the aircraft. In the actual operation of airports, the classification of aircraft based on the delay cost of flights was more conducive to airport operation and management, and improve the economic benefits of airlines and passengers. A new arrival and departure flights classification method based on the transitive closure algorithm was proposed. The fuzzy sets theory and the transitive closure algorithm were introduced. Four different factors were selected to establish the flights classification model. The formulas to calculate the delay cost for each class were given.
