Flight Arrival Scheduling Optimization on Two Runways Based on IGEP Algorithm

With the accelerated pace of life, more and more tourists’ travel mode change from the traditional land travel into air travel. It has contributed to the rapid development of the aviation industry. But also produced some problems that troubled the airline. Among them, the flight delays problem has not been effectively addressed. The cost of flight delays is still high. This paper launches the research, analyze the cause of the cost of flight delays. For the factor of terminal area flight scheduling unreasonable to improve. Combined with the two-runway actual situation of Chengdu Shuangliu International Airport, minimize the cost of flight arrival delays, construct the model of flight arrival on two runways. At the same time, the coding method, selection strategy and fitness function of GEP are improved combined with the specific problem. Finally, IGEP and simulation are utilized to solve the practical problem. Compared with the traditional FCFS rules, the cost of flight arrival delays is significantly reduced, the efficiency of flight arrival and runway utilization is improved, and the interests of airlines are guaranteed. It also shows the superiority of IGEP in addressing the issue of two-runway flight arrival.
