Embodiment
[0127] The data in this embodiment is the flight operation information from January 1, 2016 to December 31, 2016, with the starting airport being domestic based on the statistics of Feichangzhun. The fields contained in this data set are: flight number, flight date, flight scheduled departure / arrival time, actual flight departure / arrival time, aircraft type, aircraft registration number, planned departure / arrival airport, actual departure / arrival airport, airline and Flight status and other information.
[0128] 1): Define the delay rate. The definition of delay rate in this example is the definition of flight delay in the new version of the 2016 request for comments. The definition formula is the difference between the actual departure time of the flight and the planned departure time, namely: dep_delay=max(r_dep_time-p_dep_time-15, 0) . Define the average delay rate: the average delay rate is defined as the mean value of all delays within the sampling time, and its formula...
