Risk Diffusion Modeling and Vulnerability Quantification on Japanese Human Mobility Network from Complex Network Analysis Point of View

Kiyotaka Ide, Hiroshi Sato, Tran Quang, Akira Namatame
2016 International Journal of Advanced Computer Science and Applications  
In this paper, the risk diffusion dynamics is modeled based on the SIS epidemic model and the vulnerability index is defined to quantify the node-level easiness of suffering risks.  ...  However, the inter-connectivity sometimes raises unintended diffusion and amplification of the intrinsic risks, which is difficult to forecast because of the complexity of the underlying networks.  ...  So far, there exist a large number of previous works which analyze regional human mobility networks based on real data.  ...
