The project is developing methodologies for the implementation of societal, organisational and technological resilience concepts to critical infrastructure. The current report focuses on the application of technological resilience for critical infrastructure.
Chapter 4 of the report gives an overview of technological concepts which contribute to the overall resilience of critical infrastructure. The individual technological resilience concepts are grouped under the different phases of an incident occurring, namely: anticipation, absorption (and response), recovery and adaptation.
After a detailed discussion of individual resilience concepts, in Chapter 5, some engineering frameworks, centred on engineering risk assessment and the resilience triangle, are briefly presented which have promising features for practical implementation of technological resilience concepts for critical infrastructure.
Chapter 6 illustrates the application of some of the analysis methods that might be used for quantifying certain aspects of resilience. The first example presents a detailed damage assessment of a highway bridge due to a truck collision, whereas the second example describes a simplified indication of the robustness of a water distribution system against a landslide hazard.
Finally, in Chapter 7, a generic resilience assessment approach is proposed for critical infrastructure quantifying resilience conditional on hazard and defining four measureable / calculable indicators of technological resilience.
