基于航班延误特性的停机位再指派建模

摘要

Reasonable real-time gate reassignment is crucial for improving the efficiency of the airport op-eration of surface resources and the passenger service level.Based on flight delay characteristics,divided flights into certain flight and uncertain flight,a gate reassignment optimization is established with object of minimizing the total disturbance value of gate reassignment.ACO algorithm is applied in the simulation of the problem.Test result shows that: compared with the manual method,the disturbance value decreases distinctly in the 5 simulation time point,which reach 13.64%.The computation time can be as short as 184.75s,which can be preferable feasibility.%合理的停机位再指派对提高机场场面资源运行效率和旅客服务水平至关重要。基于航班的延误特性，将待指派航班分为已定航班和未定航班，分别使用不同规则建立以停机位再指派扰动最小为目标的停机位再指派模型。采用蚁群算法对模型进行仿真验证，并与人工指派结果进行比较。结果表明，在仿真验证的5个时间段，采用蚁群算法的停机位再指派仿真结果与人工指派结果相比，前者扰动值明显降低，最大降低幅度为13．64％，且蚁群算法的运行时间为184．75 s，具有较好的可行性。
