摘要
针对多跑道机场主要资源调度问题,结合层次Petri网、有色Petri网、时延Petri网和受控Petri网理论,构建一种面向机场主要资源调度的混合Petri网——HCTC_Petri(hierarchical colored timed controlled Petri)网模型。通过设置合理的控制策略、动态调节模型参数,提高运行结果的稳定性。以多个新的航班时刻表为基础,预测机场的资源调度情况。实验结果表明,HCTC_Petri网模型在模拟机场主要资源调度时具有较高的准确性和稳定性,且中转航班进站前的延误总时间和总架次对过站后的延误情况影响较大。
To solve the problem of the main resources scheduling in multi-runway airports, a modeling method named hierarchi- cal colored timed controlled Petri （HCTC _ Petri） net was built. It is one kind of hybrid Petri nets and combines with the hierarchical Petri net, the colored Petri net, the timed Petri net and the controlled Petri net. Through setting the rational control strategy and changing the parameters dynamically, the stability of the model was promoted. At the end, the resources scheduling work of the airport was predicted based on several new flight schedules. The experimental result shows that HCTC _ Petri net is more accurate and stable when scheduling main resources in the airport. Moreover, the total delayed time and flights of connecting ones have much more influence on departing flights.
