Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] The present invention provides a kind of method that is applicable to wide-area air traffic flow control, at first explain following concept and definition:

[0035] 1. Air route: an air passage with a certain width uniformly delineated by the state. There are relatively complete communication and navigation equipment, and the width is usually 20KM. The purpose of delineating air routes is to maintain air traffic order, improve space utilization, and ensure flight safety.

[0036] 2. Airline: The flight route of the aircraft is called the air traffic line, or air route for short. The route of the aircraft not only determines the specific direction of the flight, the starting point and the stopping point, but also stipulates the width and flight altitude of the route according to the needs of air traffic control, so as to maintain the order of...

Abstract

The invention discloses a controlling method suitable for wide area air traffic flow. For characteristics of the wide area air traffic flow, a large problem is divided into a plurality of small problems according to the collaborative evolutionary idea, a plurality of subpopulations are evolved at the same time in a parallel evolution way, different-direction searching is conducted, local optimum is avoided, strategies of information interaction among the subpopulations are improved, and experimental results show that a solution better than a traditional method can be obtained. According to the controlling method suitable for the wide area air traffic flow, the strategies for exchange interval dynamic change among the subpopulations in the parallel evolution are provided; and a left-right probability exchange strategy is provided on the basis of parallel evolution of subpopulation ring topology structure exchange, mixed exchange strategies are adopted for the problem, and a better result can be obtained. The controlling method suitable for the wide area air traffic flow can regulate and control the wide area air traffic flow, and can obtain a more satisfying result compared with a traditional genetic algorithm.

Description

technical field [0001] The invention relates to an algorithm for dealing with multi-objective large-scale combined optimization problems, and is a method suitable for wide-area air traffic flow control. Background technique [0002] In recent years, my country's civil aviation transportation industry has achieved rapid development. With the increasing number of aircraft in the air, the problem of airspace congestion has become increasingly serious, which not only reduces the safety of flight, but also brings huge economic losses to civil aviation. Air traffic flow management is the most effective and economical means to solve air traffic congestion. By changing the take-off time and flight path of aircraft to achieve the purpose of flow regulation, thereby reducing air traffic congestion and improving the utilization rate of airspace. [0003] The early air traffic flow regulation method mainly takes measures for local areas, especially in the terminal area. This method has ...
