Problems solved by technology

In addition, for the air traffic network, severe weather will not only affect the capacity of the route, but also affect the flight plan, that is, it will affect both the supply and demand sides of the air traffic network, resulting in an imbalance between supply and demand. Reflected in the increase of flight delays and route congestion

Embodiment Construction

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

[0011] A directed graph G(N, A) is used to represent a multi-start, multi-destination air traffic network. N is the node set, A is the edge set, R is the starting point set, S is the end point set, (r, s) is an O-D pair with r(r∈R) as the starting node and s(s∈S) as the destination node . Nodes are used to represent airports and waypoints, edges represent route segments (airlines between two waypoints, hereinafter referred to as flight segments), and routes connecting the starting node and the destination node are called routes. P rs is the set of all routes between O-D pair (r, s). For the convenience of research, the model should meet the following conditions:

[0012] (1) Each flight shall operate on the route;

[0013] (2) All flights can take off within the research time period [0, T];

[0014] (3) In order to reduce flight delays, flow control strategies such as waiting on the ground, decel...

Abstract

The invention relates to a flow scheduling method of a regional air traffic network, which is researched on the basis of the air traffic network. From the standpoint of air traffic flow, the invention researches the relation between the change of weather and the change of flight segment capacity, thereby establishing the relation between flight segment flow and travel time, discussing the relation between the reliability of the travel time of a scheduled flight and a scheduling rule under uncertain weather conditions, establishing a flow scheduling model based on Wardrop balance in the regional air traffic network, providing a method for balanced distribution of flow of each flight segment and scheduling policy of each flight route, providing decision support for air traffic planning management, and achieving the optimal scheduling of the scheduled flight.

Description

Technical field [0001] The invention is a technology aimed at air traffic network flow scheduling in the field of air traffic control, that is, the scheduling of flights is carried out by determining the travel time of flight segments under full consideration of weather factors. Background technique [0002] In the current air traffic management system, the air flow scheduling in the past is mainly concentrated in the terminal area, including takeoff flow control and landing flow control. For the flow distribution in the regional air traffic network, there are relatively few scheduling 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 regiona...
