In its broadest sense, simulation is imitation. We’ve used it for thousands of years to train, explain and entertain. Thanks to the computer age, we’re really getting good at using simulation for all three.
Simulations (and models, too) are abstractions of reality. Often they deliberately emphasize one part of reality at the expense of other parts. Sometimes this is necessary due to computer power limitations. Sometimes it’s done to focus your attention on an important aspect of the simulation. Whereas models are mathematical, logical, or some other structured representation of reality, simulations are the specific application of models to arrive at some outcome (more about models, below).
Three types of simulations
Simulations generally come in three styles: live, virtual and constructive. A simulation also may be a combination of two or more styles. Within these styles, simulations can be science-based (where, for example, interactions of things are observed or measured), or involve interactions with humans. Our primary focus at IST is on the latterai??i?? human-in-the-loop ai??i?? simulations.
Live simulations typically involve humans and/or equipment and activity in a setting where they would operate for real. Think war games with soldiers out in the field or manning command posts. Time is continuous, as in the real world. Another example of live simulation is testing a car battery using an electrical tester.

Constructive simulations typically do not involve humans or equipment as participants. Rather than by time, they are driven more by the proper sequencing of events. The anticipated path of a hurricane might be “constructed” through application of temperatures, pressures, wind currents and other weather factors.Ai??Science-based simulations are typically constructive in nature.
