Critical infrastructures risk management: case study

Abstract

The paper concerns a risk assessment and management methodology in critical infrastructures. The aim of the paper is to present researches on risk management within the experimentation tool based on the OSCAD software. The researches are focused on interdependent infrastructures where the specic phenomena, like escalating and cascading eects, may occur. The objective of the researches is to acquire knowledge about risk issues within interdependent infrastructures, to assess the usefulness of the OSCAD-based risk manager in this application domain, and to identify directions for further R&D works. The paper contains a short introduction to risk management in critical infrastructures, presents the state of the art, and the context, plan and scenarios of the performed validation experiments. Next, step by step, the validation is performed. It encompasses two collaborating infrastructures (railway, energy). It is shown how a hazardous event impacts the given infrastructure (primary and secondary eects) and the neighbouring infrastructure. In the conclusions the experiments are summarized, the OSCAD software assessed and directions of the future works identied.

Management Path of Concrete Beam Bridge in China from the Perspective of Sustainable Development

“…On the basis of traditional risk analysis methods [22][23][24][25][26], many new risk management techniques and methods have been proposed. OSCAD platform risk identification, risk response, facility recovery, and management process improvement can be realized through computer modeling [66]. The Critical Risks Method (CRM) applies six key indicators to ensure the suitability of critical infrastructure, which can effectively reduce maintenance costs [67].…”
