A New Paradigm Shift: Simulation Based Engineering Science• Numerous expert-opinion-based techniques exist for resource allocation– Difficult to extrapolate technology impacts to system-of-systems level where interactionsdominate• Decisions that shape the future of the United States Armed Forces must be enabledby advances in modeling and simulation tools, methods, and techniques [Shelton,2001]• According to the NSF Simulation-BasedEngineering Science Report (Feb 2006),simulation:– “can be used to explore new theories and todesign new experiments to test these theories”– “also provides a powerful alternative to thetechniques of experimental science andobservation when phenomena are not observableor when measurements are impractical or tooexpensive”Developing Methods and Techniques for System of Systems EngineeringDr. Dimitri Mavris, dimitri.mavris@ae.gatech.edu61
