Development of a Petri net-based reengineering simulation system: A case study

Researchers always intend to pursue the convenient and integrated tools for restoring the complexity of industrial automated systems. In this paper, a PC-based with PC Visual Basic-based (VB-Based) human-machine interface (HMI) is developed by using Petri Nets (PN) technique for the simulation of an industrial automated system. The result brings many advantages to the reality of the automated control world. It not only reduces the restore time of the automated systems, prevents the cost of equipment malfunction, but also builds the panel of the humanity for the system. The developed sequence table has proved as an important role of control process for a discrete-event control system (DECS). This paper also discusses a systematic method to convert the sequence table to Petri nets so the barriers of the conversion technique can be easily reduced.
