Embodiment Construction

[0010] Below in conjunction with accompanying drawing, describe in detail as follows:

[0011] Consider an air traffic directed network G(i, e ij ), 1≤i, j≤n, i≠j, i represents the airport node set of the network, e ij Indicates a directed arc from node i to j (i.e. flight path), whose length is l(e ij )express. Here we do the following: convert the minimum safe distance between aircraft during the flight and the corresponding route length into the flight time slot of the aircraft, that is, the maximum time slot that can be accommodated on a certain route After dealing with the air traffic network in this way, the maximum flow problem can be transformed into a discrete time form to describe. If an airport node encounters multiple take-off or landing requests, one of the requests is selected according to a certain scheduling strategy (such as first-come-first-serve, priority, etc.), and the rest of the requests are rejected in this time slot.

[0012] Assume that the avera...

Abstract

The invention relates to a novel solution method facing to flight delay, which is used for researching based on an air traffic network and calculating a maximal flow by using the disappearing probability of a derivation system of a discrete time disappearing and queuing method, thereby judging whether a flight has changing possibility. The method provides the problem of solving flight delay from a network angle, leads an airplane to fly by changing a flight as much as possible under the premise of ensuring the safe flight of the airplane, reduces the loss of passengers and increases the reputation of an airline company.

Description

Technical field [0001] The invention is a technology for solving flight delays, that is, using a discrete queuing system to solve the maximum flow of the air traffic network, thereby judging whether there is a possibility of flight diversion. Background technique [0002] At present, air traffic management is mainly concentrated in the terminal area, including take-off flow control and landing flow control. For the flow distribution in the regional air traffic network, there are relatively few dispatching research work and related reports. With the development of the civil aviation industry and the establishment of various new routes, the route maps between airports are becoming more and more networked, especially around hub airports. This route network is more common, and the congestion of a certain route will cause route network Therefore, the air traffic control research based on the regional air traffic network has become a new research hotspot. Secondly, flight delays ...
