The invention discloses a method for analyzing flight delay propagation rules. The method comprises steps: taking the flight set densities of different states at a certain moment as nodes and the conversion probability of each flight set as an edge to form a flight network between airports; counting the conversion probabilities of the flight sets in different states and the proportionality coefficient of the node density of each flight set by taking preset time as an interval; and establishing a flight delay propagation model based on a D-SEIR model according to the relationship between the conversion probabilities of the flight sets in different states and the node density of the flight sets, and analyzing the influence of each parameter size on the node density of the flight sets to obtain a flight delay propagation rule. According to the method, the flight network between airports is formed by taking the flight set densities of different states at a certain moment as nodes and the relationship of each flight set as an edge, and flight delay is considered in sections, so that spontaneous delay between flights is considered, and secondary derivative flight delay caused by the relationship between the flights is also considered.
本发明公开了一种分析航班延误传播规律的方法,包括;以某一时刻的不同状态的航班集密度作为节点,各个航班集的转化概率作为边,来构成机场之间的航班网络;以预设时间为间隔来统计处在不同状态航班集的转化概率,以及各个航班集节点密度的比例系数;以不同状态的航班集的转化概率和航班集的节点密度之间的关系建立基于D‑SEIR模型的航班延误传播模型,通过分析各参数大小对航班集节点密度的影响,来得出航班延误传播规律。本发明以某一时刻的不同状态的航班集密度作为节点,各个航班集的联系作为边,来构成机场之间的航班网络,并将航班延误分段考虑,不仅考虑到航班之间的自发延误,也考虑到航班之间的联系造成的次衍生航班延误。
