MODELLING AND SIMULATION IN DEFENCE

The use of modelling and simulation (M&S) is becoming more pervasive throughout the NATO defence environment. Simulation models use a variety of techniques, which have evolved from system dynamics, information science and operations research (OR). There are closed simulations, without human interaction, which are used primarily for research and analysis. At the other end of the spectrum there are interactive simulations with considerably active participation of operators performing, in general, the human decision making process. The latter type has been the mainstay of experimental gaming or war gaming in the past, but is now finding increasing application in the computer-assisted exercises (CAX). Thus, it can be argued that, not only are simulation models and applications expanding, but that their associated techniques can be applied across the full spectrum of functional activities of armed forces.
