Multi-Dimensional Resilience Indicator for Urban Critical Infrastructure Systems
DescriptionThis project aims to develop a novel multi-dimensional graph theory-based framework to evaluate the resilience of urban critical infrastructure systems. Networked nature of failure in interdependent critical infrastructure (such as energy, water, and transport systems) can trigger a cascading effect, disrupting the flow of goods and services in cities. Infrastructure in megacities and urban regions is already strained due to urbanization, but with increasing climate change impacts and extreme weather events, they are even more susceptible. It is imperative to develop approaches to evaluate resilience in complex systems of built environment before we can identify and engineer improvements to it. For this reason, in the 2- year project will develop a transport resilience cube methodology to evaluate the four phases of resilience cycle: prepare, withstand, recover and adapt, Future GRFs will apply this framework to demonstrate it in the context of the interdependent critical infrastructure systems of Hong Kong, including power and gas transmission, MTR transportation, and water distribution systems.
