A Three-phase Discrete Event Simulation with EPNSim GraphsDepartment of Industrial Engineering National Tsing Hua University Hsinchu, Taiwan 30043 R.O.C.
Department of Industrial Engineering National Tsing Hua University Hsinchu, Taiwan 30043 R.O.C. In the simulation world view, there are three methods of constructing a simulation in common use: event scheduling, process orientation, and activity scanning (or three- phase approach). Because the three-phase approach has advantages of both modeling flexibility and modularity, we propose a simulation modeling tool, EPNSim, extended from the ordinary Petri Nets (PNs) to generate a language-independent pseudo code for the three-phase discrete simulation. Using the proposed method, the modeling processes of the three-phase discrete simulation can be concisely represented. In addition, it preserves the relative analytic properties of the original Petri net models (e.g. boundedness, liveliness, etc.), which are important for designing a system.
