Abstract

The invention discloses an airplane scheduling module and method based on the probability theory and relates to airplane scheduling. The method solves the problem in a conventional airplane scheduling method that causes flight delay. According to the invention, emergency conditions, geographic landscape, season climate, change of demand volume, and the mutual restriction of flight lines in an airport are all taken into comprehensive consideration so that delay time and probability corresponding to delay time can be attained and an average delay time can be calculated afterwards. According to the average delay time, the take-off time of an airplane is updated. Based on the updated take-off time, the airplane is scheduled. In this manner, the flight delay rate is reduced and the flight delay can be controlled in a reduced scope as well. The airplane scheduling module and method can be applied to an airport or an airline management system.

Description

technical field [0001] The present invention relates to aircraft scheduling. Background technique [0002] The existing aircraft scheduling method is that each airline formulates a timetable according to its own situation and combined with the aircraft take-off and landing conditions at the airport, and then dispatches the aircraft according to the timetable. When the weather is bad or an emergency occurs, the flight is often delayed. , resulting in various problems such as excessive number of people stranded at the airport, reduced management efficiency of the airport's internal system, and traffic jams around the airport, which brought unnecessary losses to passengers. Contents of the invention [0003] The purpose of the present invention is to provide two kinds of aircraft scheduling modules and methods based on probability theory in order to solve the problem that the existing aircraft scheduling method easily leads to flight delays. [0004] The aircraft scheduling ...
