%0Computer Program %TEssential Function Analysis Capability %XThe Essential Function Analysis Capability (EFAC) is an extension of the All Hazards Knowledge Framework (AHA) and is a dynamic analytical framework that enables critical infrastructure knowledge discovery and decision support across the five mission areas – prevention, protection, mitigation, response and recovery. EFAC provides the ability to store and model infrastructure systems as a linked multigraphs providing an intuitive and natural representation. These infrastructure systems can then be tied to the organizational and essential function breakdown of an entity. This capability provides the foundation to rapidly evaluate and understand the potential consequences of manmade and natural disaster on these infrastructure systems and essential functions. %AHoover, Michael %AMcGillivary, Kent %ALarsen, Kenneth %AHruska, Ryan %Rhttps://doi.org/10.11578/dc.20240117.359 %Uhttps://www.osti.gov/doecode/biblio/120603 %CUnited States %D2022 %GEnglish %2USDOE Office of Environment, Health, Safety and Security (AU) %1AC07-05ID14517 2022-03-25
