Critical Infrastructures: Reliability, Resilience and Wastage

Need for Resilience in Critical Interdependent Infrastructures

Defining Resilience Resilience has emerged in the last decade as a concept for better understanding the performance of infrastructures, especially their behaviour during and after the occurrence of disturbances, e.g. natural hazards or technical failures. Recently, resilience has grown as a proactive approach to enhance the ability of infrastructures to prevent damage before disturbance events,...

Assessing Dependability and Resilience in Critical Infrastructures: Challenges and Opportunities

Critical infrastructures (CI) are very complex and highly interdependent systems, networks and assets that provide essential services in our daily life. Most CI are either built upon or monitored and controlled by vulnerable information and communication technology (ICT) systems. Critical infrastructures are highly interconnected systems and often use common ICT components and networks. Therefo...

The Road to Resilience – Critical Space Infrastructures and Space Security

Use of indicators for assessing resilience of critical infrastructures

The overall resilience of modern societies is largely determined by and dependent on resilience of their critical infrastructures such as energy grids, transportation systems, governmental bodies or water supply. This is clearly recognized by the European Union in its policies and research agenda, such as the DRS actions and projects (DRS: Disaster-Resilience: safeguarding and securing society,...

Assessing and Improving Operational Resilience of Critical Infrastructures and Other Systems

In this tutorial, we quantify resilience for an infrastructure system to a set of disruptive events in terms of degradation of system function. We show how to build and solve a sequence of models to assess and improve the resilience of an infrastructure system to those disruptions. Through simple examples and real-world case studies, we provide motivation, details of the models, and solution al...
