Foreword: Resilient and Sustainable Interconnected Critical Infrastructure Systems

Written by Wentao Zhu

There is widespread agreement that critical infrastructure security and resilience must be enhanced. In the UK, sector security and resilience plans provide the strategic vision to guide the national effort to manage risk to the Critical National Infrastructures (CNI) [1]. Nevertheless, the complexity of CNIs and their inherent interdependencies make it difficult to realise this aim. Therefore, research efforts are devoted to developing new methodologies for understanding and consequently, managing the risks associated with interconnected CNIs.

---

Assessing the CNIs’ interdependencies requires the accurate modelling and simulation of complex and multidimensional elements. Analytical methodologies, such as Complex Network Theory (CNT)-based approach, provide efficient yet flexible means to understand the non-trivial risk elements within coupled CNIs [2]; whereas co-simulation platforms are useful in developing new technologies and evaluating existing methods [3].

The August Special Issue includes three articles on this important topic of smart cities. The first article develops a co-simulation environment to enable the investigation of the threat of cyberattacks with a detailed simulation of multiple domains of interest within smart cities. The second article introduces the concept of data-driven maintenance management of smart cities critical infrastructures, with a demonstrative case study of energy distribution systems' maintenance management scheduling. The third article provides a review of critical emergent issues in managing emergencies and thus enhancing the resilience of smart cities, from a system-of-systems perspective. The last article introduces two recent international events that involve high-level discussions of interconnected critical infrastructure systems and their resilience and sustainability issues.
