SyntheSim is so called because it allows you to use Simulation to Synthesize the structure and behavior of a model. Events, behavior and structure are often presented as a hierarchy of ways of looking at the world with events arising from underlying behavior patterns and behavior arising because of structure. Simulation models represent the structure which, through simulation, generates the behavior. The connection between structure and behavior is strong, but it can be difficult to gain an understanding of how structure causes behavior. By superimposing behavior on structure and instantly updating behavior as you make changes, SyntheSim provides you with a new and very powerful tool for understanding your model.
