Airport delay performance evaluation based on fuzzy linear regression model
Wei Dong-xuan · 2010
In order to effectively evaluate the delay performance of airport,taking into account that the weather and traffic variable values were usually subject to some uncertainty factors,the features of traffic demand and weather were used to develop a fuzzy linear regression model for airport arrival delay,and the estimated delay was computed.The continuous baseline to measure operational airport delay performance was obtained by comparing estimated delay with actual delay.The delay performance could be evaluated based on the delay baseline.Analysis result indicates that the features of traffic demand and weather have a strong linear relationship with airport arrival delay,which can be fitted with the model.The delay performance baseline takes into account the impact of airport weather and traffic demand on the delay,and divides the delay into low,medium and high levels,and the delays of different days can be compared and evaluated.1 tab,2 figs,21 refs.
