Application: A Resilience Assessment Framework for Infrastructure Systems

The effective integration of resilience into national and homeland security policies requires that resilience transforms from a primarily abstract concept into an operational and measurable one. This transformation can be facilitated through the development of formal and transparent analysis methods that provide precision, clarity, and defensibility. This research effort developed a three-part infrastructure resilience assessment framework to address that challenge.  The framework is demonstrated through an application to chemical manufacturing supply chains.

• Goal
• Create and apply an infrastructure resilience assessment framework that formalizes infrastructure resilience analysis.
• Approach/ Methods/Models
• Explore previous methods for characterizing resilience
• Identify gaps
• Create infrastructure resilience assessment framework
• Apply framework and hurricane scenarios to petrochemical supply chain model
• Status, Accomplishments and NextSteps:
• Created 3-part infrastructure resilience assessment framework. Primary components include:
• Definition of resilience
• Equations for quantifying resilience
• Systems analysis approach for identifying system features that constrain or enhance resilience
• Hurricane resilience case study for petrochemical supply chains
• Apply framework to various infrastructure systems to demonstrate its general applicability to all infrastructure systions
• Research the integration of optimization methods with the framework to optimize resilience
