Resilience and Vulnerability-based Decision Support System (RV-DSS)
15 June, 2018
The Resilience Shift attended this event organised by Dr Donya Hajializadeh and Dr Maryam Imani.
This seminar is focused on the application of the Resilience and Vulnerability-based Decision Support System (RV-DSS) on a case study in North Argyll, Scotland. At this seminar, we aim to bring together academics and industry practitioners with extensive experience from three key sectors of water, energy and transport to discuss the application of the RV-DSS, in providing a measure of network resilience in response to hazardous events. Our project was in collaboration with Transport Scotland, SSE, Scottish Water and ATKINS and funded by the Natural Environment Research Council (NERC).
About the RV-DSS Project:
The frequency and magnitude of environmental hazards in Scotland and across the UK in general, have increased significantly in the last decade, resulting in widespread failures in Critical Infrastructure (CI) networks.
Breakdowns of interdependent and integrated CIs disrupt essential services and result in severe consequences for asset owners and managers, users and the wider community. The common challenge currently faced by asset owners and managers is the lack of a robust resilience-informed business planning and management strategies in response to interdependent assets failures, in particular due to low-probability / high-impact environmental hazards.
Interdependencies among CIs can cause cascading failures and hence amplify negative consequences due to these failures. This can also affect CIs service restoration rate and consequently reducing their resilience in coping with these hazardous environmental events. As infrastructures are becoming more interdependent in some sectors, there is an increasing need for a better management of these interactions and interdependencies.
To reduce these impacts, an integrated Resilience and Vulnerability-based Decision Support System (RV-DSS) is developed to map interdependent network vulnerable components and to introduce adaptive capacities accordingly. This is of particular importance as CIs owners and managers are investing substantially in improving the resilience of their assets in response to extreme environmental hazards.
RV-DSS is adopted in a case study of North Argyll, Scotland. The interdependencies in transport, energy and water networks and the failure propagation due to these interdependencies is assessed.
