摘要
由于一架飞机一天要执行多个航班,使得航班之间存在前后衔接关系,因而一个航班的延误会波及到与之衔接的下游航班,造成航班延误链式反应。基于时间Petri网理论,对单架飞机执行多个航班提出了时间Petri网链式模型,并给出了具体算法,用于在初始延误时间已知的条件下,判断初始延误机场的下游机场是否出现航班延误并计算航班延误的时间。实例仿真及分析表明,航班延误链式反应波及的机场个数与飞机的初始延误时间存在一定的量化关系,机场可以参考这个量化关系,根据初始延误时间建立航班延误预警机制。
There is a connective relationship among the flights due to one airplane implementing a few flights. Thus one delayed flight might propagate the downstream flights, and causes flights delay chain reaction. Based on the theory of Petri nets, a timed Petri nets model was established for one airplane to implement a few flights. A propagated analysis algorithm was given to judge whether the lower reaches of the initial delayed airport delay when the initial delayed time was known, and calculated the delayed time. Simulated experiments and analysis demonstrate that there is a certain quantitative relation between the number of the delayed airports which were propagated by the chain reaction of the flights delay and the initial delayed time. The airport can refer to the quantitative relationship and establish flights delay early warning mechanism according to the initial delayed time.
