Analysis Of Regional Airport Route Network Hierarchy And Route Optimization

With the increasing density of global air transportation and the increasing overall strength of the country,regional airports have become an integral part of regional economic development and will continue to play a pivotal role in the future.Therefore,coordinating the development of regional airports has become a new trend in the future development of civil aviation,and only through this way can we better promote the development of regional economies and achieve a higher level of economic growth and social progress.The route network is the key link between airport clusters.Therefore,it is especially important to analyze and study the basic hierarchical structure of the route network and route optimization.By studying the hierarchical structure and route optimization of airline networks,we can better understand the connections and needs of different airports and design more efficient and sustainable airline networks to meet the growing travel demands of people.To this end,this thesis uses complex network related theories to analyze the structural characteristics of route networks,and based on which an airport node importance model is established and the hierarchical structure of airport nodes and routes is divided,and finally a route optimization model is constructed to optimize the routes of regional airports.The purpose of this thesis is to discuss the hierarchical structure analysis and route optimization of regional airport route networks.In terms of hierarchical structure analysis.Firstly,the national route network is firstly constructed and the structural characteristics of the route topology network are analyzed in depth using complex network theory.Then,a connectivity model is established based on several network characteristics indicators,and the connectivity capacity of each airport node in the region and the connectivity of the whole regional airport network are analyzed quantitatively and qualitatively.On this basis,a node importance evaluation model was constructed,and the importance of each airport node was calculated using the TOPSIS method modified by the entropy weight method;two clustering methods were integrated to classify each airport node into tiers,and finally the routes connected by regional airports were divided into three tiers: trunk routes,transitional routes and regional routes,and this route tier division was used as the basis for the study.In terms of route optimization,a regional airport route network optimization model is proposed with reference to the P-hub median problem with the minimum transportation cost as the optimization objective,and a modified simulated annealing algorithm is used to solve it.The whole thesis takes Chengdu-Chongqing airport cluster as an example to optimize the passenger flow distribution and route layout of the regional airport system in order to balance the efficiency and economy of the overall operation of the regional airport network as much as possible,and provide some reference significance for the development and optimization of the regional airport route network.
