Analysis And Predicting Of The Aircraft Boarding Duration

With the rapid growing of the airport volume,it has brought serious challenges to efficient operation of airport internal business and the management of the aircraft turnaround.Aircraft turnaround process includes flight ground support services,deboarding and boarding process.Boarding process is the last process in aircraft turnaround,and studying on the boarding duration distribution is of great importance in optimizing the flight sequence before taking off.Aircraft boarding duration distribution model and real-time dynamic adjustment of the aircraft boarding duration are studied in this paper.The specific works are as follows:For the research of distribution,the actual operation data of Beijing Capital International Airport is pre-processed firstly,and the analysis of the main influence factors of boarding duration indicates that aircraft type,gate position,arrive time and arrive time deviation influence the boarding duration extremely.For the uncertainty of the boarding duration,distribution fitting method is adopted to fit the distribution of boarding duration in this paper and estimate the parameters are estimated basing on the operation data of Beijing Capital International Airport.The derived distribution model considers the main influence factors,such as aircraft type,gate position,arrive time,and is proved to be reasonable and dependable under different combination conditions.With regard to the phenomenon of serious deviation in arrival time triggering large prediction error,a real-time dynamic adjustment is proposed in this paper.Experiment shows that the prediction of the aircraft boarding duration and real-time dynamic adjustment improve the prediction accuracy greatly.
