Abstract

Simulation is the process of designing a model of a real or imagined system and conducting experiments with this model to understand the behavior of the system or to evaluate strategies for its operation. Assumptions are made about this system and mathematical algorithms (q.v.) and relationships are derived to describe these assumptions--this constitutes a "model" that can reveal how the system works. If the system is simple, the model may be represented and solved analytically. A single equation such as DISTANCE = (RATE * TIME) may be an analytical solution representing the distance traveled by an object at constant rate for a given period of time.
