航班延误是指航班降落时间(航班实际到港挡轮挡时间)比计划降落时间(航班时刻表上的时间)延迟15分钟以上或航班取消的情况。航班延误问题是各个国家、各个航空公司高度重视的事情,因为它不仅仅会影响用户的出行安排、出行心情,也会影响到航空公司的效率,甚至是一个国家的名声。笔者将通过对数据的基础采集、系统整理进行层次分析,搭建了有色Petri模型以及时间Petri网模型,通过链式分析、波及分析等,制作出模型优化解决方案,综合性分析我国航班延误问题是否在全球范围内最严重以及造成航班延误的原因,最后提出相关的改进措施。
Flight delay refers to the delay of more than 15 minutes or cancellation of flight between the landing time of the flight (the actual port of rotation of the flight to the port) and the scheduled landing time (time on the flight schedule). The problem of flight delays is a high priority for all countries and airlines because it will not only affect users’ travel arrangements and travel mood, but also affect the efficiency of airlines and even the reputation of a country. Through the analysis of the basic data collection and system arrangement, the author builds a colored Petri-model and a time-Petri net model to make a model optimization solution through chain analysis and wave analysis, and comprehensively analyzes whether the flight delay problem in China The most serious cause in the world and the reasons for the delay in the flight, finally put forward the relevant improvement measures.
