Abstract:

In order to relieve the congestions and delays at busy airports with large flow and high density of air traffic, an optimized method for multi-runway spatio-temporal resource scheduling in the mode of independent departures is proposed in this work. Firstly, from the perspective of the field of production scheduling, multi-runway departure scheduling problem is regarded as an NP-Hard combinatorial optimization problem of typical job shop scheduling. Secondly, the optimization targets of flight delays, runway capacity and pollutant discharge amounts of aeroengine are established by deeply analyzing the needs of the stakeholders in air transportation industry, then an optimized model is established considering the restricts such as wake turbulence separation, surface taxiing separation and runway crossing separation. Finally, an elitist non-dominated sorting genetic algorithm (NSGA-Ⅱ) is designed combined with the multi-objective optimization theory and applied to solving the problem of multi-runway scheduling to search for Pareto optimal solutions. Simulation results show that the above model and algorithm can achieve optimized scheduling for aircraft in the mode of independent departures, effectively reduce the flight delays and pollutant discharge amounts of aeronautical engine and improve the runway capacity. Compared with the rand and alternate scheduling strategy of multi-runway, the optimized one brings about a striking effect which results in a 51.2% and 42.7% reduction in flight delays. The proposed method can significantly relieve the flight delays of departures at large busiest airport and effectively improve the service quality of air transportation.
