Ontology-based approach to disruption scenario generation for critical infrastructure systems

Abstract

The systematic and complete identification of relevant disruption scenarios for Critical Infrastructure (CI) systems is still one of the major challenges to achieve higher resilience performance. We assist Authorities and Operators in this endeavour through creating a comprehensive and multi-dimensional allhazards catalogue for CI. It is implemented by developing two ontologies: • CI systems Ontology, covering Energy, Transport, Water and Telecommunications sectors, each being described through two sub-ontologies (physical and functional) interconnected within the service delivery topology.; • Hazards & Threats Ontology, characterising different typologies of events, their attributes, types and possible effects to CI systems. The two ontologies are connected through vulnerability and (inter)dependency models. The main results achieved include: i) a generalised and standardised specification framework for CIs and services; ii) a generalised and standardised all-hazards catalogue for CI; and iii) an improved scenario generation process to support CI risk assessment.

Resilient Critical Infrastructure Planning Under Disruptions Considering Recovery Scheduling

“…In fact, generating a set of relevant disruption scenarios is a part of the CI identification process (e.g., the EC Directive 2008/114/EC requires to develop relevant failure scenarios of a CI in order to assess the transboundary impacts on other Member States), which has attracted much attention [70]- [72]. In practice, methods like the hierarchical ontology [71] could be used to identify different types of SLD events faced by a CI system. For each SLD type, sophisticated models (e.g., for earthquakes [56] and storms [57]) can be used to generate a subset of relevant disruption scenarios, e.g., the most likely and the worst-case scenarios, by examining what the potential threats to the CI systems are and how the system components are affected.…”

Geographic ontology for major disasters: Methodology and implementation

“…Zong et al [19] proposed an ontology representation of meteorological disaster system. Trucco et al [20] developed a critical infrastructure systems ontology, and hazards and threats ontology, connected through vulnerability and interdependency models as a multi-dimensional hazards catalogue for critical infrastructure to support risk assessment, Alirezaie et al [21] presented a framework named SemCityMap in which satellite images are classified and augmented with additional semantic information to enable queries about finding paths on a particular location in a disaster situation (simulation of flood) using existing ontologies and a developed ontology named OntoCity.…”

Exploiting Web Ontologies for Automated Critical Infrastructure Data Retrieval

“…Conceptual models that target cyber dependencies are considered in [45], where a human factors ontology is employed to specify a cyber security framework. Other researchers [66,67] discuss an ontology-based approach for vulnerability and interdependency representation as well as disruption scenario generation for critical infrastructures. Luo et al [40] have developed a knowledge modeling formalism for emergency situations and planning in metropolitan areas, and have implemented it in a training tool.…”
