Abstract
A discrete event system (DES) modeling environment models the occurrence of events independent of continuous model time. In a DES modeling environment, state transitions depend not directly on time, but rather aperiodic discrete incidents known as events. A discrete event modeling environment can be used to model a control system using one or more discrete event-driven components. The event-driven components can be used to model certain portions of a control system that cannot be accurately modeled using a time-based model.
