Research On Network Design And Optimization Of Aviation Alliance

With the intensification of internal competition in civil aviation and the initial scale of the “eight vertical and eight horizontal” high-speed rail network,the competition of domestic civil aviation transportation has reached a feverish level.More and more airlines are focusing on the international market,and the aviation alliance is expanding the international market.In a way that works well,many domestic airlines have joined the airline alliance.Due to lack of relevant experience,domestic airlines still have certain blindness in the development of alliance cooperation,especially the construction of route networks,and lack of a scientific and rational theoretical method to guide cooperation.This article takes the alliance route network as the entry point to study how airlines build route networks to meet economic and stability needs.Firstly,using complex network theory to analyze the characteristics of the three major airline alliance routes,the main statistic parameters such as the average path length,degree and degree distribution of the alliance route network are obtained,and the characteristics of the alliance route network are analyzed to provide reference for constructing the alliance route network.Secondly,it constructs the evaluation index of the hub airport selection in the alliance network,highlights the transfer effect of the hub airport,and analyzes and evaluates the candidate hub airport by using the modified fuzzy analytic hierarchy process to determine the candidate hub airport.Under the determined scenario,with the minimum operating cost as the objective function,a strict multi-allocation alliance route network model is constructed.The model is improved,and the non-hub airports are directly connected under the premise of satisfying certain conditions,and non-strictly multi-allocation is constructed.The alliance route network model and the model example verification show that the improved model has a great improvement on the alliance network economy.Finally,considering the uncertainty of the air transportation environment,a robust optimization model of the alliance route network with uncertain demand and cost is constructed.At the same time,considering the limitations of the discrete scene set,the discrete set is extended to the interval range.The example proves that the route network has strong robustness and compares the structural changes of the network under certain uncertain and uncertain scenarios.
