Abstract

The invention discloses a method for optimizing layout of convergent points of air routes by introducing airspace capacity. The method comprises the following specific implementation processes of: firstly, establishing a flowrate model of an air route network; secondly, determining the maximum density of scheduled flights bearable for the air route network according to the degree of crowdedness imposed to the air route network by different densities of the scheduled flights; and thirdly, carrying out the optimal layout of the convergent points of the air routes. The method puts forth the quantitative airspace capacity description method by establishing the traffic flowrate model for the air route network, constructs the multi-objective optimization model based on flight efficiency and theairspace capacity, and optimizes the positions of the convergent points of the air routes by adopting a multi-objective particle swarm algorithm. The method takes both the flight efficiency and the airspace capacity into consideration, and the obtained air route network can effectively postpone the occurrence of the airspace congestion under the circumstance of increasing of aviation flowrate.

Description

technical field [0001] The invention relates to a new method for optimizing the layout of route convergence points by introducing air space capacity, and belongs to the field of route convergence point optimization. Background technique [0002] With the rapid development of civil aviation, the flight traffic has increased sharply, and the existing air route structure has been difficult to meet the needs of the increasing air traffic flow. Therefore, it is necessary to re-plan the existing air route network to meet the new needs of the air transport industry for the air route network under the new situation. [0003] The air route network planning aims to analyze the structural defects of the current air routes and routes exposed in the diversification of air transport demand and the rapid development of flight traffic, and according to the distribution characteristics and development trends of traffic flow, combined with air traffic control guarantee conditions, use traffic...
