We consider the problem of assigning gates to a large airline at its hub airport in both planning and operations mode. The first objective in planning mode assigns airport gates for a given passenger flow data and pedestrian distances between the gates, such that maximum connection revenue is realized. The second objective aims to schedule flights to gates in as few manpower zones as possible to minimize operating costs. The third objective ensures that the time between a departure and next arrival at the same gate is maximized to ensure reasonable schedule robustness in the event of delays.
