CIRCAS (Constellation of Intelligent Reasoning for Constructive Analytic Simulation) is a Federate designed to provide an agent based reasoning layer capable of controlling entities within other approved Federates. CIRCAS uses intelligent agents to model the operations and performance of organizations, units, individuals and systems driven by a realistic message flow generated by a force-on-force simulation. This helps the analyst evaluate the performance of nuclear detection systems and sensors in realistic operational environments using virtual forces.
Early detection of threats is key to successfully combating nuclear terrorism. To model an information architecture in a force-on-force simulation tool, Alion engineers developed the Constellation of Independent Reasoning for Constructive Analytic Simulation (CIRCAS), built upon the Repast Simphony, an open source, agent-based modeling and simulation platform product of Argonne National Laboratory.
CIRCAS uses intelligent agents to model the operations and performance of organizations, units, individuals and systems driven by a realistic message flow generated by a force-on-force simulation. It effectively provides an artificial intelligence front end to the simulation that removes the need for a human-in-the-loop, enabling faster than real-time execution in parallel instances for analytic applications.
The decoupled nature of the agent-based modeling environment allows for the user to quickly see how changing the environment, force structure or unit capabilities affects the mission and what sensitivities the architecture may have to each of those factors. CIRCAS can be federated with any HLA-compatible entity level simulation that supports the RPR FOM order-response framework as an underlying simulation.
