Heuristics of node selection criteria to assess robustness of world airport network

Chinese Journal of Aeronautics 2017年第4期30卷 1473-1480页

作者： Manel SORIA Oriol LORDAN josmaría SalLAN Department of Physics Aeronautics Engineering Universitat Politecnica de Catalunya-BarcelonaTech Terrassa 08222 Spain Department of Management Universitat Politecnica de Catalunya-BarcelonaTech Terrassa 08222 Spain

The world airport network（WAN） is one of the networked infrastructures that shape today＇s economic and social activity, so its resilience against incidents affecting the WAN is an important problem. In this paper, the robustness of air route networks is extended by defining and testing several heuristics to define selection criteria to detect the critical nodes of the *** addition to heuristics based on genetic algorithms and simulated annealing, custom heuristics based on node damage and node betweenness are defined. The most effective heuristic is a multiattack heuristic combining both custom heuristics. Results obtained are of importance not only for advance in the understanding of the structure of complex networks, but also for critical node detection.
