中文摘要：
研究进场飞机序列鲁棒性,选择合适的进场排序方法是提高进场空域利用率的有效办法.针对现有进场飞机排序算法较少、考虑不确定性因素影响的不足,在定义进场序列鲁棒性的基础上,建立基于马尔科夫链的进场飞机序列鲁棒性指标评估模型;并对某机场实际飞机落地时间误差数据进行统计与分析.得出飞机落地时间近似服从高斯分布.最后对比分析了1-CPS序列和带缓冲的FCFS序列在不同误差分布下的鲁棒指标与性能.结果表明,相比带缓冲的FCFS,1-CPS方法有效提高了进场序列的鲁棒性,这与实际情况吻合.而采用高斯分布近似表示飞机落地时间分布,与之前研究中以三角形分布作为落地时间分布相比,两种序列的鲁棒指标均提升了4倍多.同时也更贴近实际运行环境,获得的进场序列鲁棒指标更具实际参考意义.
