Multirunway Optimization Schedule of Airport Based on Improved Genetic Algorithm by Dynamical Time Window

Table 1

The safety interval of various types of aircraft.

	Types of aircraft	Tailing
		Minimum distance interval/km			Minimum time interval/s
		L	M	H	L	M	H
Leading	L	3	3	3	98	74	74
	M	4	3	3	138	74	74
	H	6	5	4	167	114	94

H, M, and L represent three kinds of flight type; they are heavy, medium, and light.
