Research on Joint Ground Movement Optimization Based on Bilevel Programming

Requirements of digitization, intellectualization, and integration for the programming management air transportation have been recommended as information technology booms. A variety single ground movement optimization problems discussed with few taking impact other segments into account. In this research, bilevel is applied to simultaneously consider three including gate assignment, taxi path scheduling, pushback time delay. For evaluating strategy assignment measuring its connection taxiing comprehensively, an auxiliary variable matching degree aircraft are introduced. addition, algorithm incorporating genetic routing designed obtain a solution satisfactory performance in both conflict risk. The scheme obtained also assigns gates more appropriately maintains characteristics environmental protection well high efficiency, showing considerable reliability practice.
