Abstract:

In order to reduce the adjustment of control plan caused by uncertain air route block time between the departure
airport and the destination airport, in a data-driven manner, time optimization of airports at both ends of the air
route was conducted by establishing a strategic and tactical two-stage stochastic programming model targeting
uncertainty in air route block time. And the sample mean approximation algorithm was used to solve the problem
to improve the uncertainty of the air route operation time and reduce the adjustment of the control plan. Taking
the flight schedule of Beijing Capital International Airport and Guangzhou Baiyun International Airport at the
winter-spring season of 2021 as an example, the adjustment amount of control plan of the optimized flight schedule was reduced in the tactical stage, and the uncertainty of air route operation time was improved. By comparing
the schedule block time of air routes under different weights, suggestions for reducing the planned block time of
air routes were proposed to improve the operation efficiency of flight schedule planning.
