中文摘要：

针对我国枢纽机场日起降高峰小时的航班拥堵常态化问题，从系统整体运行效能的角度，针对枢纽机场终端区跑道系统容量瓶颈，①分析性能基导航（Perfor—mance—BasedNavigation，PBN）模式下枢纽机场终端区的空域结构、飞行、管制程序，根据随机服务系统理论，建立其运行模型；②考虑PBN模式下航班、旅客的延误滞留函数和机场单位时间服务支出函数；③再应用排队论和系统运行效能理论，建立枢纽机场最佳跑道数目需求算法，能根据相关参数计算航班滞留时间和队长等指标；④最后引用某枢纽机场相关数据，演算结果符合实际抽样调查统计资料．

英文摘要：

To solve the airport flight take-off and landing congestion problem, discussed the operation efficiency of hub-airport terminal area system. The paper structure as follows： （1） analyzed the airspace structure, flight and control procedure of airport terminal area beneath PBN mode operation, established the operation model by using the stochastic service system theory; （2） considered the flights, passengers delay stranded function, and the airport service spending functions; （3） applied queuing ＆ system operation efficiency theory, obtained a algorithm of runway-requirement~setting-amount. Using the relevant parameter can calculate flight detention time and queue length; （4） quoted related data of one airport to calculate, results accord with the actual observation statistics.
