Synopsis of NISAC Modeling Capabilities
NISAC designed advanced modeling and simulation capabilities to analyze critical infrastructure vulnerabilities, interdependencies, and complexities. These analyses are used to aid our nation’s decisionmakers in policy-making,
assessments, mitigation planning, education, training, and real-time assistance to crisis response organizations.
The domains in which we work are large, complex, dynamic, adaptive, nonlinear, and behavioral; they are too complex for mental models to be effective decision tools. Our capabilities can identify when/where things break, and any cascading effects. We can quantify consequences of disruptions in very complex systems, such as a loss of a single asset or node within a particular system due to a directed attack, or regional disruptions due to a natural disaster or large-scale attack. The rational choice is to experiment with models, not the system, thereby gaining expert operational insight through modeling.
Models used for any given analysis range from realistic to abstract, depending on the questions being posed.
Analysts study the details of individual infrastructures, from the asset to the system level, interactions between infrastructure, and how critical infrastructure respond.
Natural disasters or imposed threats require NISAC analysts to employ their knowledge of different infrastructures along with a variety of capabilities, including modeling and simulation, to provide real-time assistance to decision makers.
