Discrete event dynamic system explained

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
