摘要: 由于一架飞机在一天中要执行多个航班,各航班之间存在前后衔接关系,因此,一个航班的延误会波及到下游许多其它航班。重点研究飞机和机组资源对于航班延误与波及的影响,给出延误树的生成过程,通过初始航班延误的触发,动态建立以该航班为根结点的航班延误树,并根据统计结果给出相关量值。实例分析了初始航班延误发生的时刻、持续时间与波及的程度,以期辅助优化飞机与机组排班,减少航班延误。

Abstract: Because an airplane is needed to carry out several scheduled flight services in a day,of each service linked another,one delay will propagate to the other.This paper investigates the aircraft and crew resources for the influence of flight delay and propagation and describes the process of creating a delay tree.Triggered by beginning flight delay,it developments a delay propagation tree with initial flight as its root and statistic some metrics.It analyzes the relationship among the time of day,the duration of initial delay and the propagation in an instance.Its purpose is to help the optimization of aircraft and crew schedule,thereby reduce the flight delay.
