Abstract:

In this paper we summarize the realization methods in discrete event simulation, discuss system requirements on how to handle parallel behaviors well.  Then it presents a timed Petri net model. In this model, a simulative object is considered the basic unit,and complex events＇ time-stamp is discussed,   , which is used as a proof to make parallel events be processed correctly and effectively. Additionally, the method solves exceptions well in the process of simulation

Key words: simulative object, layer, timed-Petri nets, priority queue
