The design of a simulation system for the lift. This is a discrete simulation program, because the elevator system and elevator passengers and other " physical activities" constitute a collection, although they interact with each other, but their behavior is a fundamental independent. In discrete simulation, to simulate the activities of body clock each time the action took place and order. Moment in a simulation system to deal with a variety of things to be done, and then the simulation clock advanced to an action scheduled to take place the next time.
