WTI has a record of excellence in formulating, refining, and improving the modeling and simulation (M&S) methods and processes that support operational force training. We embed simulations in one-on-one computer-based training, classroom exercises, and force-on-force exercises. Our applications are widespread and include simulated satellite communications (SATCOM) in various operational configurations that permit training in managing downgraded system performance challenges; IT computer systems and networks where training can be conducted in analysis, monitoring, and maintenance of those systems; and test operations scenarios on which military leadership can practice command and control functions. We produce models that support cost and schedule estimation, system analysis, performance predictions, and other statistical analysis support.
