Abstract:A approach based on the Timed Petri net (TPN) for incorporating water integrating in batch process scheduling was presented in this paper. Firstly, the Petri net model of process scheduling was built and the scheduling can be obtained using the incidence matrix analysis method. Then the Petri net model of the water integration was established according to the water cascading analysis, the principles of water network design and the water matching rules. Finally, based on the facility of multiple view integrated modeling, the Petri net models of the scheduling and water-using network synthesis were combined to achieve the optimization of the scheduling and water integration in batch process. An example was presented to demonstrate the validity and advantages of the proposed approach.
