Description

Technical Field

[0001] The present invention belongs to the technical field of airport transfer hub capacity assessment, and in particular relates to a method for calculating a multi-scale airport network flight transfer comprehensive index. Background Art

[0002] The Airport Network Flight Transfer Index is a quantitative indicator used to assess an airport's ability to serve as a transfer hub. It measures an airport's transfer capacity by calculating all available flight connections at the airport, taking into account both the shortest and longest transfer times, based on global flight data. The higher the index, the stronger the airport's transfer capacity. Specifically, the Airport Network Flight Transfer Index can be assessed from the following perspectives:

[0003] Proportion of connecting flights: the ratio of all planned connecting flights to all potential connecting flights;

[0004] Feasible transfer times: the total number of actually operable transfer flights;

[0005] Average transfer waiting time: the average transfer waiting time of all actually operable transfer flights;

[0006] Transfer success rate: the ratio of the total number of actually operable transfer flights to the total number of planned transfer flights.

[0007] In summary, the airport network flight transfer index is a crucial indicator of significant importance for the healthy and orderly development of the civil aviation industry. By comprehensively optimizing airport network flight transfer resources, airline operational efficiency can be effectively improved, enhancing the passenger travel experience. Currently, existing technologies rarely address the comprehensive, multi-scale dynamic assessment of the airport network flight transfer index, its spatial distribution, and its dynamic mechanisms. The mechanisms and processes of multi-scale airport network flight transfer levels vary across airports and regions, necessitating a dynamic risk situation awareness methodology to address this issue.
