摘　　要：为了预防许多飞机被置于繁忙目标机场等待航线的不可控状态,空中交通管制的地面控制策略(GHPs)依靠增加地面等待来减少空中等待时间。应用混杂系统理论,对每个工作的事件驱动建立一个当时状态模型,时间驱动建立一个物理状态模型。对CHPs最重要的是确定哪些工作应该在被等待和等待多长时间。基于这个框架,给出了GHP的一个有限扰动分析(FPA)方案来动态解决等待时间问题。以此来分析模拟从某机场获得的数据并得出有意义的结果。In order to prevent uncontrollable situations where a number of airplanes are placed in a 'holding pattern' over busy destination airports, hybrid system theory capture the essence of Ground-holding policies (GHPs) in air traffic control which aim at trading off unavoidable airborne delays for ground delays. Associated with each job is a temporal state subject to event-driven dynamics and a physical state subject to time driven dynamics. The fundamental issue in GHP is to determine which jobs should be delayed and for how long. Based on this framework, we address the GHP and propose a finite perturbation analysis (FPA) technique that can be used to dynamically solve the problem. Some useful results based on data from an international airport are found.
