Simulation: It's the Real Thing

摘要

Almost everyone has heard the term simulation, but who knows what it really means. Is simulation represented by a wargaming effort, such as Pacific Air Forces (PACAF) units participating in a TEAM SPIRIT exercise. Or, is a better example provided by a C-5 aircrew practicing emergency procedures in a cockpit mockup. Perhaps simulation is best demonstrated by somebody analyzing a computer-based model to determine the expected number of backorders of some reparable item for the Joint Strike Fighter. Whatever simulation means, the military seems to think it is worthwhile. A few examples: Joint Vision 2010 specifically cites simulation as a method of improving training realism, promoting readiness and assessing operations concepts. The DoD Directive for defense acquisition requires that 'modeling and simulations shall be used to reduce the time, resources, and risks of the acquisition resources'. Finally, the DoD has established a modeling and simulation master plan and an entire organization to address simulation issues.
