Research On Airline Route Network Optimization Based On Air-Rail Intermodal Transport

Rapid development of high-speed highway has brought about a series of problems to civil aviation transportation industry,meanwhile,the air transportation industry in our country has not been further enhanced.Rapid development of hub airport has destroyed the benign development of civil aviation thus to cause feeder airport to lose development vitality gradually under the background of rapid development of high-speed highway,which will certainly cause the transport capacity of flight in hub airport to suffer from overloaded operation.As a result,the feeder airport will become shrunken increasingly while the hub airport will become stronger and stronger.However,punctual probability of flight in hub airport will certainly affected owing to large pressure thus to influence the operation efficiency of airport.Besides,many aviation enterprises in our country will also be limited to some extent based on research and analysis.In order to break through the aviation development trend of focusing on trunk line but neglecting branch line,fresh concept of “hub+” is proposed in this paper based on traditional aviation-highway combined transport to establish large-scale public transport system and realize integration of hub and branch line thus to provide reference for airline development and selection of aviation enterprises and provide richer selection for tourists in travelling.Firstly,the influencing factors of high-speed highway on aviation industry is analyzed in details,and related literatures are collected and studies based on research on network optimization of hub airline,meanwhile,the overseas development situation is also focused and qualitative analysis is conducted for related successful experience in overseas;secondly,the quantitative method is adopted to collected related data of domestic high-speed highways and civil aviation based on 31 domestic classic cities.Besides,the hub distribution point is measured to divide the levels of hub cities to get hub candidate sets,the aviation-highway compound network model is established and the traversal search algorithm is adopted to get solution.Based on traditional aviation-highway compound network model,the traversal search algorithm is programmed to design the master algorithm and subalgorithm,and the Matlab is used to conduct simulation verification to get the quantity of different hubs based on hub candidate sets,combined transport route based on discount factor,central terminal station cities and total cost of combined transport,in addition,the simulation result is summarized and presented through forms,and the simulation result is compared carefully to get the conclusion.Based on practices,the applicability of aviation-highway combined transport and “hub+” are proved.In accordance with the last optimization result of the model,the economic cost and time cost of shortest route for traditional aviation-highway combined transport and aviation-highway combined transport based on “hub+” can be calculated,what's more,the through transportation cost,combined transport cost and “hub+” cost can be compared to get the following conclusions: the quantity of hubs and discount degree can affect the quantity of combined transport routes,traditional point-point through transportation is not the best route,and “hub+” is superior to traditional aviation-highway and through transportation.These research results provide reference for optimization and adjustment of airline network of aviation enterprises as well as exploration of new airlines,and provide better choice for people in travelling,which are of certain guidance significance.
