Application of Hybrid Petri Net in Modeling of Process Industry’s Production Logistics

After analyzing the production process of the oil refinery, the production logistics simulation model of the whole oil refinery was set up using the hybrid Petri net. This model includes not only the discrete event dynamic system but also the continuous-variable dynamic system and it is consistent with the production practice. Based on the hybrid Petri net model, the production logistics could be optimized timely according to different objective. Finally, the framework of the simulation system was introduced and an example of the simulation was explained.
