Abstract: The capacity of the area control sector is an important factor affecting the normality of flights. In order to reduce flight delays, based on the capacity and flow matching of the area control sector, while considering the airline's flight slot resource allocation袁the Shanghai Pudong International Airport's peak period flights are modeled and analyzed, with the shortest total flight delay time as the goal, with airport capacity, area control sector capacity, and flight schedule adjustments as constraints, the flight schedules were fine-tuned and optimized袁and software simulation is used to compare and verify the data obtained before and after optimization of flight schedules during the period. The results show that the optimization of Pudong Airport's flight schedule has greatly reduced the total flight delay time of the airport while ensuring that the airline's resource allocation remains basically unchanged.

Key words:  flight schedule optimization, area control sector, capacity flow matching, flight time resource allocation
