Research on the Multi Time Scale Characteristics Analysis and Fitting Model of Flight Waves
In order to rationally allocate the flight schedule resources of large transport airports and improve the ground opera-tion efficiency of flights during peak hours of airport operation,the intrinsic characteristics and fitting models of flights in large trans-port airports are studied.Firstly,the Lempel-Ziv algorithm is used to calculate the flight time series of different time scales,and the correlation and inherent evolution law of flight waves with time change are studied to obtain the optimal time scale for flight wave re-search,then the Pearson correlation coefficient is introduced to analyze the flight wave time characteristics to verify the correlation between flight waves and longitudinal timing.Finally,the sine function is used to fit the flight wave and the fitting error is analyzed.The example shows that the fitting performance of the sinusoidal function is better than that of other function models,and the model obtained in this study can accurately characterize the correlation between the flight wave parameters and the fluctuation law of the flight wave at the airport.
