Embodiment Construction

[0036] In order to be able to understand the above objects, features and advantages of the present invention more clearly, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments may be combined with each other under the condition of no conflict.

[0037] A method for optimizing the spatial layout of airport clusters based on accessibility, such as figure 1 shown, it includes:

[0038] Step 1: Area meshing for the predetermined area

[0039] For a predetermined area A, use a square grid of m×n km (n>0) to fill the area A, and divide the area A into n 1 line n 2 Column sub-regions, that is to say, cover all region A, where any sub-region can represent (i, j):

[0040]

[0041] where: N 1 ={1,2,3,...,n 1 -1,n 1 } represents the set of position numbers i;

[0042] N 2 ={1,2,3,...,n 2 -1,n ...

Abstract

The invention relates to a reachability-based airport group spatial layout optimization method, which comprises the following steps of: 1, carrying out regional grid division on a predetermined region; 2, randomly generating m feasible airport group layout strategies Pm based on a grid division result of the region A; 3, establishing an airport group space satisfaction model, and constructing an objective function Z according to airport distance satisfaction; 4, model calculation; 5, layout optimization iteration adjustment is carried out; and step 6, obtaining an airport group space layout strategy Pm and a global optimal solution Pg, and outputting and calculating the maximum airport group space satisfaction max Z. The airport group system structure and space distribution can be reasonably planned, the bottleneck of the overall service quality of the airport group is broken, the operation efficiency is improved, and support is provided for improving the service quality of the airport group system.

Description

technical field [0001] The invention relates to the technical field of optimization methods. Specifically, it relates to a method for optimizing the spatial layout of airport clusters based on accessibility. Background technique [0002] In the field of transportation planning and major project management, most of the related researches on the unbalanced development of the airport cluster system focus on the coordinated operation and management of the airport cluster, and the research on the spatial planning and layout of the airport cluster system is rare. However, compared with the collaborative operation management method, a reasonable spatial planning and layout of the airport group system is the basic premise to break the bottleneck of the overall service quality and operation efficiency of the airport group, and it is also an important support for optimizing the airport airspace flow and operation management methods. In order to analyze the influence of the spatial la...
