Exponential synthetic networks
Exponential Synthetic Networks

CD = 100

CD = 200

CD = 300


Topological hazard tolerance
Topological Hazard Tolerance

  • Assessed by subjecting the networks to:

  • Degree attack strategy

  • Random hazard


Spatial hazard tolerance
Spatial Hazard Tolerance

  • Assessed by using a ‘central attack’ spatial hazard

    • Remove nodes in order of their distance from the centre of the network




Conclusion
Conclusion

  • To date little work has been done on spatially distributed networks

  • Space has a small but important effect on the degree distribution of a network and can have a significant effect on the hazard tolerance

  • We have developed a network model which is capable of capturing the growth of infrastructure systems in terms of both their network architecture and geographical distribution

  • This can be used to form an assessment of their hazard tolerance to spatial hazards
