Discrete event dynamic system

In control engineering, a discrete-event dynamic system (DEDS) is a discrete-state, event-driven system of which the state evolution depends entirely on the occurrence of asynchronous discrete events over time. Although similar to continuous-variable dynamic systems (CVDS), DEDS consists solely of discrete state spaces and event-driven state transition mechanisms.

Topics in DEDS include:


 * Automata theory
 * Supervisory control theory
 * Petri net theory
 * Discrete event system specification
 * Boolean differential calculus
 * Markov chain
 * Queueing theory
 * Discrete-event simulation
 * Concurrent estimation
