ABSTRACT
Risk management is one of the approaches to improve the efficiency and safety of critical infrastructure against extreme events. This approach focuses on the design of robust CI and strong protection systems. In this way, the probability and consequences are minimized. However, extreme events are increasing in both number and severity. CIs (especially those built in the past) find it difficult to withstand and adapt to these extreme events. As a result, a recent dramatic shift has shifted from robust design to focus on preparedness, response, and resilience. Accordingly, CI can withstand the majority of adverse effects at higher-than-normal thresholds. In the event of destruction or damage, the CI can bounce back to normal operation more quickly with minimal resources. Increasing understanding and improving the resilience of CI to extreme events contribute to sustainable cities. Although considerable research has been conducted on the resilience of Critical Infrastructures systems over the years, it still has gaps. This paper applies the Digital Twin concept to the infrastructure domain to improve CI system resiliency. A comprehensive analysis of the critical infrastructure characteristics and resilience is implemented. The results show that the Digital Twin has the ability to fill research gaps, enhancing the resilience of critical infrastructure.
