Abstract

Resilience in a critical infrastructure system can be viewed as a quality that reduces vulnerability, minimizes the consequences of threats, accelerates response and recovery, and facilitates adaptation to a disruptive event. In this context, comprehensive knowledge of the environment and of the main factors whereby resilience is determined, limited, and affected can be said to represent the fundamental precondition for strengthening the resilience of critical infrastructure elements. Based on this idea, the article defines the initial and functional conditions for building and strengthening the resilience of critical infrastructure elements, i.e., the resilience concept in a critical infrastructure system. Subsequently, factors determining the resilience of these elements are identified, both in terms of technical resilience (i.e., robustness and recoverability) and organizational resilience (i.e., adaptability). In the final part of the article, these factors are presented in greater detail in the context of case studies focused on the electricity, gas, information and communications technology, and road transport sectors. Determination of these factors is examined with regard to the intensity of a disruptive event and the performance of the respective critical infrastructure element. View Full-Text
