Abstract
The hub airport was made for transit. Recently construction of the air route around the hub airport is an important problem, because a big airport was made and an air route was liberalized. O'Kelly thought about the hub airport location problem. He formulated the model that arranged a one or two hub airport, and he formulated as the linear programming problem to choose the hub airport of the n unit to minimize total transit cost among candidate given hub airport. The studies of a placement of hub airport as the optimization problem were developed by them researches, and much solution is proposed. In this research, a solution is calculated from this problem using Ant colony optimization.
