An Airport Stand Assignment Problem considering the Passenger Boarding Distance

Algorithm 1

The NSGA-II algorithm for stand assignment pseudocode.

	Input: , , , , , , , , , ,
(1)	Get by  +
(2)	Initialize the population (·)
(3)	for to do
(4)	Selection cells in mating pool
(5)	Crossover and mutate of cells
(6)	Offspring cells into new population
(7)	if stand assignment not satisfy constraints then
(8)	Regenerate and replace set of flights’ stands
(9)	end if
(10)	Calculate objective functions result
(11)	Nondominate sort the cells
(12)	Calculate the crowd distance
(13)	Sort population in descending order
(14)	end for
	Output: Best solution for stand assignment
