  1. Modelling Infrastructure Systems for Resilience and Sustainability Sarah Dunn, Sean Wilkinson, Gaihua Fu and Richard Dawson

  2. Analysis of Infrastructure Systems Underlying Network Architecture Vejvodova (2006)

  3. Scale-Free Networks Exponential Networks • The Internet • (Albert, et al. Nature: 1999) • The World-Wide-Web • (Albert, et al. Nature: 2000) • Electrical Distribution Systems • (Sole, et al. 2008) • Airline Networks • (Wilkinson, et al. 2012) Carvalho, et al. (2009) Newman (2003)

  4. Network Generation Algorithms • Scale-free network generation algorithm: Barabasi, A. L. and Albert, R. (1999). "Emergence of scaling in random networks." Science 286(5439): 509-512.

  5. Network Generation Algorithms • Exponential network generation algorithm: Wilkinson, S. M., Dunn, S., and Ma, S., (2012) ‘The Vulnerability of the European Air Traffic Network to Spatial Hazards’ Natural Hazards. 60(3): 1027-1036.

  6. Topological Hazard Tolerance • Infrastructure networks have been shown to be: • Resilient to random hazard

  7. Topological Hazard Tolerance • Infrastructure networks have been shown to be: • Vulnerable to targeted attack

  8. Development of Spatial Network Model • Starts with the input of initial conditions • Seed node locations and their geographic influence • The remaining nodes are then added individually • Each cluster can attract new nodes • New nodes located randomly within cluster • Each cluster expands with added nodes
