Abstract
Abstract Critical infrastructures are the backbone of our societies with increasingly complex and networked characteristics and high availability demands. This makes them vulnerable to a wide range of threats that can lead to major incidents. Resilience is a concept that describes a system’s ability to absorb and respond to disturbances, as well as to learn from the past and anticipate new threats. In this article, we apply the Digital Twin concept to the infrastructure domain to improve the system’s resilience capabilities. We conduct a comprehensive requirements analysis related to infrastructure characteristics, crisis management and resilience measures. As a result, we propose a Digital Twin Conceptual Framework for critical infrastructures. We conclude that the Digital Twin paradigm is well suited to enhance critical infrastructure resilience.

Summary
Zusammenfassung: Kritische Infrastrukturen sind das Rückgrat unserer Gesellschaften, die zunehmend komplexer und vernetzter werden und hohe Anforderungen an die Verfügbarkeit stellen. Infrastructures are exposed to manageable disruptions and failures, and to extreme events such as extreme weather events, mechanical failure, human failure, accidents, attacks, and previously unknown and non-specified events. With its up-to-date nature, integrated smart and adaptive functions, and digital methods, the Digital Twin concept represents a potential approach to the field of infrastructure services. Tual object can increase the resilience of infrastructure services at the operational level Based on these introductory assumptions, in this paper, we examine in more detail the applicability of the Digital Twin concept to improve resilience of critical infrastructure operation and protection. We first derive implementation requirements from the scope of critical infrastructure, crisis management and resilience methods, which we map to the Digital Twin concept. We show that the Digital Twin paradigm is well suited for a framework that promotes increased resilience in all phases of a crisis
