An overview of operational gaming/systems simulation. Four separate areas must be distinguished: analytic models, machine simulations, man/machine simulations, and free-form games. Analytic models are usually too abstract to solve operational problems directly, but give insights into sources of difficulty. Computer simulation appears to have been oversold; a shakedown is occurring, and many expensive simulation programs go unused. The difficulties of modeling, specification, data gathering, validation, sensitivity analysis, question formulation, and answer recognition make general-purpose simulators impossible. In man/machine gaming, people may be used because they are cheaper than software, or because human factors are being studied. Free-form gaming involves individuals acting in a scenario; other than the value of their time, costs are miniscule. Simulation costs are probably at the order of $100 million yearly. Conclusion: The future of gaming and simulation is quite good; demand is growing and technology is improving; but the growth must be controlled. 21 pp.

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
