Abstract To investigate strategies for mitigating the scarcity of gate-connected parking stands and diminishing carbon emissions at airports, this study employs mathematical modeling to analyze stand allocation strategies for aircraft of varying sizes under different levels of airport congestion. Research shows that considering the carbon dioxide emissions of aircraft, a parking stand allocation scheme with lower carbon emissions can be obtained, aligning with the energy-saving and emission-reduction philosophy advocated by practical enterprises. Solving the original mixed-integer programming model of the problem directly using commercial solvers, or solving the parking stand allocation problem with the branch-and-price algorithm, both approaches take too long. In contrast, the proposed heuristic branch-and-price algorithm can obtain approximate optimal solutions for large-scale instances within a reasonable time. The congestion level of the airport has a minimal impact on the performance of the heuristic branch-and-price algorithm, which is suitable for airports with varying levels of congestion.
