Abstract

The invention provides a causal relationship analysis method and device. The method comprises the steps of obtaining flight operation state data of an airport to be determined whether a flight delay causality exists or not through a server; calculating the arrival delay duration of the flight of the airport based on the flight operation state data; constructing a flight delay time sequence of theairport based on the arrival delay duration of the flight of the airport and the flight operation state data, calculating the transfer entropy between the two airports based on the flight delay timesequence of the airport, and determining whether there is a flight delay causal relationship between the two airports or not according to the transfer entropy. Whether the delay causal relationship exists between the two flights or not is analyzed through the server, so that the server has the capability of processing the data about whether the delay causal relationship exists between the two flights or not.

Description

technical field [0001] The present invention relates to the field of flight delays, and more specifically, relates to a causality analysis method and device. Background technique [0002] With the rapid development of today's air transport industry, the number of flights operated by airlines has increased significantly, and flight delays have followed. The travel uncertainty caused by flight delays not only brings great inconvenience to passengers, but also brings huge economic losses to airlines, which has become a major challenge to the current air transportation system. Since upstream and downstream flights share aviation resources, such as aircraft, crew, and airport ground resources, etc., when the upstream flight is delayed, the downstream flight will also be delayed with a high probability. This phenomenon is called delay propagation. If there is no reasonable way to control delay propagation, the spread of delay will continue to expand. Due to the current developme...
