Design of Computer Simulation• Computer simulation is a numerical technique forconducting experiments on certain types ofmathematical and logical models describing thebehavior of a system (or some componentthereof) on a digital computer over extendedperiods of real time. (Burdick & Naylor, 1966)• Design of Computer Simulation (DoCS) is gearedtoward developing sound experimental designpractices foe experiments performed oncomputational simulationsDeveloping Methods and Techniques for System of Systems EngineeringDr. Dimitri Mavris, dimitri.mavris@ae.gatech.edu31
