Abstract:

As the convergence part of the airfield and terminal area at an airport system, the runway causes frequent air traffic congestions and flight delays due to the unbalanced demand and capacity. In this work, an optimized method for multi-runway spatio-temporal resource scheduling in the mode of dependent approaches is proposed to improve the service ability of multi-runway systems. By analyzing in depth the spatio-temporal characteristics of multi-runway systems and taking into considerations the control handoff separation, wake turbulence separation, longitudinal separation, and slope separation, an optimized model is established to balance different factors of interest such as safety, economy and environment. Then an elitist non-dominated genetic sorting algorithm is designed in combination with the multi-objective optimization theory, and applied to solve the problem of multi-runway scheduling. Simulation results show that the above model and algorithm can achieve optimized scheduling for aircraft in dependent approaches, and it can effectively reduce flight delays as well as pollutant discharges of aeronautical engines. Compared with the random and alternate scheduling strategy of multi-runway, the optimized model brings about a striking effect of 39.3% and 32.6% reduction in flight delays. The method which is entirely applicable to the mode of independent approaches can significantly relieve the flight delays at large busy airports, and effectively improve the flight punctuality rate.
