Abstract:

The problem of shortage of airspace resources and the flights’delay has become increasingly serious with the rapid development of civil aviation and growth of air traffic flow. According to the actual operation of the airport and the case that cargo flights can land or take off on a fixed runway only, this paper studies the optimization of sequencing and the assignment of runways for arrival and departing flights when air traffic congestion happens in an airport. A model of sequencing arrival and departing aircraft on parallel runways that includes cargo flights is set up. And then the genetic algorithm (GA) of dual codes is employed for the model to determine the sequencing strategy and assign the runway for each arrival or departing flight with a pair of chromosomes. The simulation demonstrates that the proposed model can verify the cargo flights land on the required runway, reduce flights’delays and increase air traffic flow more effectively compared with the result of first come first service(FCFS) sequencing algorithm.
