    1. Continuous-Variable Dynamic Systems(CVDS) must satify:

      (1)They are continous-state systems.

      (2)The state transition mechanism is time-driven.

    2.Discrete Event Dynamic Systems(DEDS) must satify:

      (1)The state space is a discrete set.

      (2) The state transition mechanism is event-driven.

    3.definirion.

      A Discrete Event System(DES)is a discrete-state,event-driven system,that is, its state evolution depends entirely on the occurence of asynchronous discrete events over time.

    4.We should not confuse discrete event systems with discrete-time systems.

      The class of discrete-time systems contains both CVDS and DES.A DES may be modeled in continuous or in discrete time.

    5. Three levels of abstraction at which DES are modeled and studied:

      untimed(or logical), timed,and stochastic.

    6. Two discrete event modeling formalisms will be presented and studied:automata and Petri nets.
