Characteristics Of China Airline Network Based On Coreness Tunable Network Model

With the rapid and steady economic growth,the aviation industry has made overwhelming progress.China airline network has been continuously expanding.Therefore,with the increasing travel demand,passages request for efficient and convenient travel service.Consequently,the establish of more airports and new airline routes leads to the complexity and latent risk of aviation industry.So,exploring characteristics of China airline network has important theoretical and practical significance.To research the characteristics of China airline network,both the static topological characteristics and invulnerability of the network should be aimed for in-depth analysis.Briefly,it includes two aspects:static and dynamic failure.The static failure only estimates the changes in the network structure,while the dynamic failure takes the load of the actual network into account.The broadcast of failure can lead to the large-scale network collapse.Therefore,by adopting the related theories of complex network and by the means of simulation,the paper systematically examines the nature of China airline network.It mainly includes the following aspects:(1)The coreness tunable network(CTN)model is proposed base on the results of empirical research.(2)Simulating the China airline network by CTN model and comparing the basic statistical characteristics of CTN model and the real aviation network,the paper proves that both the networks share the scale-free characteristic and small word effects,and CTN model is applicable to the Chinese airline network.(3)Implementing random attack and targeted attack to validate the structural robustness of the model network and the real aviation network,which we measure the topology structure by the average efficiency of the network and the relative size of the max connected sub-graph.It concludes that model network and airline network have strong survivability against random attacks,and CTN model has better survivability than airline network against targeted attacks.(4)By adopting SIR propagation model and simulating the congestion diffusion process,the paper studies the congestion diffusion process of CTN and China airline network comparatively.The research results show that both CTN and airline network have strong ability to suppress congestion spread against random attack,CTN has stronger ability to suppress congestion spread than airline network against targeted attack,and final congestion scale of network is proportional to propagation probability.In addition,ranking the nodes importance of network with the consideration for dynamic failure by simulating,the results indicate that the most important nodes are located in the inner core of both CTN and China airline network.
