“…Various researchers and practitioners have come up with a list of the so-called critical infrastructure considering a variety of factors such as social services, economy and security issues. For example, the EU Directive report of 2008 [30] defines critical infrastructure as "those assets, systems or parts thereof that are essential for the maintenance of vital social functions, health, security, safety, economic and social welfare of people, whose destruction or malfunctioning would have as a direct consequence a significant impact on population, as a result of a loss of service of these functions". In the United States, the Department of Homeland Security lists sixteen critical infrastructure sectors whose assets, systems and networks, whether physical or virtual, are considered as vital to the security, national economic security, national public health or safety or any combination thereof.…”

“…Furthermore, the official announcement of MWA (http://gisonline.mwa.co.th/GIS1125/index-desktop.php) shows numerous instances of intermittent water supply for operational and maintenance purposes, which carry the risk of floodwater intrusion into the water supply system (e.g., in September 2016, there were 1472 cases of this nature; in October 2016, there were 873 cases; in November 2016, there were 987 cases, etc.). Figure 14 depicts the locations of leakages in relation to flood-prone areas, and Figure 15 depicts the locations of leakages in relation to potential Escherichia coli concentrations in the floodwater (see also [30]). These two figures were obtained from the results of the 1D-2D model simulations.…”

Impacts from floods in urban areas can be diverse and wide ranging. These can include the loss of human life, infrastructure and property damages, as well as other kinds of nuisance and inconvenience to urban life. Hence, the ability to identify and quantify wider ranging effects from floods is of the utmost importance to urban flood managers and infrastructure operators. The present work provides a contribution in this direction and describes a methodological framework for analysing cascading effects from floods that has been applied for the Sukhumvit area in Bangkok (Thailand). It demonstrates that the effects from floods can be much broader in their reach and magnitude than the sole impacts incurred from direct and immediate losses. In Sukhumvit, these include loss of critical services, assets and goods, traffic congestion and delays in transportation, loss of business and income, disturbances and discomfort to the residents, and all these can be traced with the careful analysis of cascading effects. The present work explored the use of different visualization options to present the findings. These include a casual loop diagram, a HAZUR resilience map, a tree diagram and GIS maps.

“…An alternative methodological approach is suggested by Guikema (2009) based on statistical learning theory. Franchina et al (2011) proposed an impact-based approach to model the cascading effects. Based on probabilistic elicitation approaches and expert judgments, Chang et al (2014) characterized infrastructure vulnerability and community resilience focusing on infrastructure interdependencies.…”

Modeling infrastructure system interdependencies and socioeconomic impacts of failure in extreme events: emerging R&D challenges

2015

Greater urbanization does not only mean higher concentrations of population and economic activities, but also increasing complexity and infrastructure interdependencies in the delivery of critical urban services such as energy, water, transport and communication. This paper reviews the current literature in these areas and identifies critical research and development challenges from the perspective-and for the benefit-of key stakeholders, considering their primary decision goals and context. From this vantage point, the critical evaluation framework is extended to include a classification of disruptions and extreme events and an overview of infrastructure modeling approaches and broader socioeconomic impacts assessment methods. Mapping the range of modeling and assessment methods against different decision contexts, critical gaps in knowledge and tools are identified to support the latter. Deep uncertainties characterize the challenge as each major component in the information and decision-making chain-from the frequency and intensity of a disruptive event, to assessing the first-order and immediate impacts of an infrastructure failure, to estimating the nature, extent and impact of cascading failuresmultiplies the uncertainties. The emerging research challenges to deal with these interdependencies and uncertainties are discussed.

“…This is inherent to all the empirical risk approaches -empirical risk-based approaches analyse dependencies based on previous incidents (historical incident or disaster data) coupled with expert opinion to identify alternative measures that minimise the dependency risk (e.g., Franchina et al, 2011;Utne et al, 2011). It is unlikely for a single critical infrastructure owner or operator to have access to real data about other CIs.…”

This paper applies research in dependency modelling to a process-based risk assessment methodology suitable for critical infrastructures. The proposed methodology dynamically assesses the evolution of cascading failures over time between assets involved in a business process of an infrastructure. This approach can be applied by a CI operator/owner to explore how a failure in a single component (asset) affects the other assets and relevant business processes. It could also be applied in an analysis that includes multiple CI operators in the same supply chain to explore the dependencies between their assets and explore how these affect the provision of key societal services. The paper presents a proof-of-concept tool, based on business-process risk assessment and graph modelling, and a realistic case example of a rail scheduling process. The approach allows risk assessors and decision makers to analyse and identify critical dependency chains and it can reveal underestimated risks due to dependencies.Keywords: risk assessment; business process; asset; dependency; cascading failures; risk chains; likelihood; impact; critical infrastructure.
