Abstract
Airport congestion witnesses potential conflicts: insufficient terminal airspace and delay propagation within scrambled the competition in the terminal manoeuvring area. Re-scheduling of flights is needed in numerous situations, heavy traffic in air segments, holding patterns, runway schedules and airport surface operations. Robust optimisation for terminal traffic flow problem, providing a practical point of view in hedging uncertainty, can leverage the adverse effect of uncertainty and schedule intervention.
This research considers the problem of decision-making in the terminal manoeuvring area during the uncertain arrival times at entry waypoints of flights and investigates the air traffic controller specific parameters in the model. The problem is formulated in a two-stage optimisation framework and the proposed methods further enhance the quality of Paretooptimality Benders-dual cutting plane based on core point approximation in the second stage optimisation problem.
In addition, the model could determine the estimated average delay time at runways with different settings of additional
buffer for longitudinal separation requirement and trade-off parameters between the estimated average delay time at runways and estimated penalty cost of cruise speed adjustment. The numerical results show that the proposed scheme outperforms the well-known Pareto-optimal cuts in Benders-dual method from the literature.
