CD = 100 CD = 200 CD = 300
TOPOLOGICAL HAZARD TOLERANCE
Assessed by subjecting the networks to:
Random hazardDegree attack strategy
SPATIAL HAZARD TOLERANCE
Assessed by using a ‘central attack’ spatial hazard Remove nodes in order of their distance from the centre of the
network
SPATIAL HAZARD TOLERANCE
SPATIAL HAZARD TOLERANCE
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
