摘要
为了提高机场场面运行效率和机场空侧容量,亟需采取积极的手段对滑行路径进行优化。根据滑行路径规划的问题属性,选取离场航班为研究对象,建立了以滑行时间最短为目标函数的无冲突滑行路径优化模型,并设计了基于滚动时域与混合整数线性规划(MILP)相结合的迭代算法;将滑行路径优化模型植入空域管理与评估系统(ACES)的空侧容量评估系统中,以杭州萧山国际机场场面数据为例,对不同策略下的航班滑行时间、容量评估结果及路径更改次数进行了比较分析,验证了模型的准确性,通过比较MILP与新算法下的计算时间验证了算法的高效性。
Optimization of taxiway routing is an effective method for improving of surface operation effi-ciency and airside capacity .According to the characteristic of taxiway scheduling problem ,an optimization model aimed at reducing taxiing time of departure flight with no conflict was established ,MILP based on receding horizon was designed to solve the model which made the computing performance significantly im -proved.Finally,the model was implanting the optimization model into evaluation system of airport airside capacity of ACES under ordinary strategy and optimization strategy of Hangzhou Xiaoshan International Airport were compared and analyzed ,actual instance verified the accuracy of the model .
