To deal with the problem of arrival scheduling and sequencing(ASS) is the main way to keep air traffic unobstructed and reduce flights delay.According to the characteristics of ASS problem,an object function with total delay is developed,an improved genetic algorithm based on Grefenstette coding and receding horizon control strategy is proposed,then the scheduling model with genetic algorithm is simulated in this paper.The results of the simulation show that compared with first come first serve(FCFS) algori...
