Exploring current state-of-the-art approaches to the prioritisation of components in interdependent infrastructure systems
What originally started as a (very long!) literature review section in a modelling framework paper, evolved into a standalone paper exploring how the current state-of-the-art approaches the prioritisation of components (assets) in interdependent infrastructure systems, what is considered critical and how such systems can be modelled, further exploring social justice and equity dimensions therein.
The paper finds that there is significant variability in definitions, modelling approaches and criticality and prioritisation quantification criteria. Lead author Alex Chatzistefanou indicates a need for more research to develop frameworks grounded in formal definitions of infrastructure criticality, incorporating the full resilience cycle of infrastructures therein, addressing the socio-technical nature of CI systems and developing methods for validation, calibration and uncertainty analysis of such models. He also stresses that social equity is largely ignored in engineering frameworks for infrastructure asset criticality assessment and prioritization, highlighting an important direction for developments.
