Our proposal is constructed around a mature, government-owned, distributed simulation architecture known as Joint Force Operational Readiness Combat Effectiveness Simulator (JFORCES) and a proven three-step computer-aided methodology known as Rapid Relational Modeling (RRM). The proposal includes definition, structuring and prioritizing of project goals and requirements using consensus of end-user expert groups, developed through RRM sessions, facilitated by experienced contractor staff members. Our proposed application, modification/enhancement and expansion of current JFORCES capabilities includes demonstration of integrated Network-Centric SoS concepts and demonstration of relevant capabilities; 1) to evaluate alternative C4/ISR sensors, weapons and communications concepts at the system, subsystem and component levels (at all echelons of joint service operation, including controlled environmental perturbation and reactive/adaptive OPFOR), 2) to evaluate the specific contributions of SoS elements to alternative military ops concepts, in effects-based scenario executions, and 3) to support seamless integration and synchronization of disparate real-time hardware and software simulations (such as RF emitter simulation, GPS constellation emulations, and detailed C4/ISR simulations). These functions are supported by Analytical Module tools embedded in the JFORCES testbed environment that has been successfully applied to numerous government programs for After Action Reporting (AAR) and engineering analyses
