基于SCPN的机场航班进离港流程建模与仿真

Airport Flights Arrival and Departure Process Modeling and Simulation Based on SCPN

通过对航班进离港流程的分析,拟建立一种基于随机着色Petri网的机场航班进离港流程模型,设置其库所和变迁颜色集合得到航班的复合颜色,并赋予变迁不同的随机时间延迟函数,使模型更符合实际运行特点。在此模型基础上,以航班为仿真对象,在ServiceModel平台上实现了浦东国际机场航班进离港流程仿真系统。最后进行了大量的仿真试验,仿真结果较真实地再现了机场的实际运行情况,得出了航班进离港流程中的实际到达时间、跑道小时容量、停机位利用情况等关键指标,对于机场飞行区的规划设计以及其日常运行有重要参考价值。

According to the analysis of flight arrival and departure, a model for airport flights process will be built based on SCPN, its place and transition color collections will be set to get flight composite color, and different stochastic time delay function to transitions will be given. The model will accord with actual operating characteristics. In this model, flights for the simulation object, in ServiceModel platform, the flights arrival and departure process simulation system of PVG International Airport were achieved. The simulation result is in consistent with the practical operational situation by many trials, and count the key indicators of STA, runway capacity per hour, gate utilization etc. It pays a key role on the design and planning of airside as well as the daily operation.
