The description of the Industry 4.0 cyber and physical production division based on Petri net models

The Industry 4.0 production division base is cyber and physical systems. They function automatically using some additive technologies, the Internet of things technology, sensors technologies and etc. To project the cyber and physical production divisions they can use some mathematical models based on Petri nets. The Petri nets let describe and research discrete events processes which are a part of cyber and physical production division. A Petri net structure is given to describe production processes in the Industry 4.0 devices designing company. The Petri net model is done in the environment VisualPetri 1.2.
