Research On Route Network Optimization Of Regional Multi-hub Airports Cooperative Development

"From a worldwide perspective,many cities or regions have two,three or even more Large hub airport" is multi-airport that are a region where the air transport industry has developed to a situation of maturity.So Regional Multi-hub airports around the world have basically formed,but most Regional Multi-hub airports have some problems such as unclear positioning of division of labor,internal distribution imbalance,and unreasonable route network structures.Research on the coordinated development of Regional multi-hub airports is still in its infancy.Therefore,this research takes the regional multi-hub airport as the research object.,the route network of regional multi-hub airports is studied and optimized from the perspective of coordinated development.First,based on the concepts of "hub airport" and "airport group",and the current global regions are identified through quantitative criteria of regional multi-hub airports.Then,the operation mode of coordinated development of regional multi-hub airports is summarized.By analyzing the development status of regional multi-hub airports in the world,and learning through typical cases such as New York,Tokyo,and Istanbul multi-hub airports,and from the perspectives of domestic and international markets,international markets,and airline route network layouts respectively,the methods of coordinated development of regional multi-hub airports are described.Secondly,it defines the connotation of "coordinated development of regional multi-hub airports route network",and constructs a comprehensive evaluation model of regional multihub airports route network coordination degree from the aspects of integrity and difference,and uses the principal component analysis method and SPSS statistical analysis software calculating the evaluation of the degree of synergy of route networks of multi-regional hub airports in the world.So this research derived the comprehensive ranking of the degree of coordination of the hub group and the ranking of each principal componen,which pointed out the direction for regional multi-regional hub airports to improve the degree of synergy of route networks.Based on the results of comprehensive evaluation of regional multi-hub airport route networks,this research builds an optimization model of the route network that takes the total transportation cost of regional multi-hub airports to the minimum,and the Shanghai hub group is taken as an example to select routes with high route overlap and connecting smaller airports to optimize.Finally,according to the above analysis and calculation,this research puts forward the strategy of coordinated optimization of the regional multi-hub airport route networks,which will provide some reference significance for the future research on the coordinated development of regional multi-hub airports.
