“…The theory is useful to identify components (that in this case are called actors) of urban systems. The term "component" is generally used to descript the physical existing elements in infrastructural systems [2,[32][33][34][43][44][45]. Nevertheless, in this research, we will uniformly use "component", signifying "actors", for describing the physical or abstract existents in social and infrastructural systems.…”

“…The functional analysis allows the understanding of the functional behaviour of a system or its components facing external hazards, analysing its failures, reconstructing the failure scenarios, and determining the most efficient or critical parts of the system. Then, it is possible to identify the cascading dysfunctions analysis and failure mode analysis [33,34,44,45].…”

“…We can differentiate two studied subsystems: infrastructural systems are mainly characterised by a greater number of nonhuman components in the built environment, while social systems are mainly characterised by a greater number of human components in the social environment (Figure 2). Therefore, identifying how infrastructural systems and social systems depend on each other means analysing the functional connections between the components of the two systems (Figure 1, number 2) [32][33][34]. Based on functional dependencies, this study further aims to understand the potential cascading effects and possible failure modes to define interdependencies between the two systems to improve resilience (Figure 1, red line).…”

Resilience of Social-Infrastructural Systems: Functional Interdependencies Analysis

Critical infrastructures serve human activities and play an essential role in societies. Infrastructural systems are not isolated but are interdependent with regard to social systems, including those of public health and economic and sustainable development. In recent years, both social and infrastructural systems have frequently been in dysfunction due to increasing natural or human-made disasters and due to the internal and external dependencies between system components. The interconnectedness between social-infrastructural systems (socio-economic systems and technical-infrastructural systems), implies that the damage to one single system can extend beyond its scope. For that reason, cascading dysfunction can occur and increase system vulnerability. This article aims to study the functional interdependencies between social-infrastructural systems and to propose a methodology to analyse and improve the resilience of these systems. Combining Actor Network Theory and the Functional Models approach, the social-infrastructural Interdependence Resilience (SIIR) framework was proposed. To assess the applicability of the approach, the framework was applied to study the interdependence of a social-infrastructural system in the Nantes Metropolis. The studied system was composed of the local Highway Infrastructure (an infrastructural system) and the Emergency Medical Service (a social system). The results (1) show the feasibility of SIIR for investigating the interdependencies of two urban systems, and (2) provide a guideline for decision-makers to improve the functional interdependencies of urban systems.

Local floods induce large-scale abrupt failures of road networks

et al. 2019

The adverse effect of climate change continues to expand, and the risks of flooding are increasing. Despite advances in network science and risk analysis, we lack a systematic mathematical framework for road network percolation under the disturbance of flooding. The difficulty is rooted in the unique three-dimensional nature of a flood, where altitude plays a critical role as the third dimension, and the current network-based framework is unsuitable for it. Here we develop a failure model to study the effect of floods on road networks; the result covers 90.6% of road closures and 94.1% of flooded streets resulting from Hurricane Harvey. We study the effects of floods on road networks in China and the United States, showing a discontinuous phase transition, indicating that a small local disturbance may lead to a large-scale systematic malfunction of the entire road network at a critical point. Our integrated approach opens avenues for understanding the resilience of critical infrastructure networks against floods.
