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。 Due to the fact that an aircraft is to operate multiple flights in a single day and there is a back-and-forth link between flights, delays in one flight can affect many other flights downstream. Focusing on the impact of aircraft and crew resources on the delay and spread of flight, the generation process of delay tree is given. The flight delay tree with the flight as the root node is dynamically established through the trigger of the initial flight delay, and the correlation is given according to the statistical results Magnitude. The example analyzes the timing, duration and spread of initial flight delays in order to assist in the optimization of aircraft and flight crew scheduling and reduce flight delays.
