Extended Petri Net-Based Simulation Modeling and Analysis

Starting from the extended event process chain (EEPC) and traditional Petri net, the extended Petri net model based on EEPC is proposed. This model can reflect the logical structure of the process, make a quantitative calculation and judgment of such factors as time, thus guaranteeing the correctness and validity of the process analysis qualitatively and quantitatively. Each step of this new model is introduced. The proposed model is validated through a real-world hospital BPR case study.
