Poly-model description of Industry 4.0 cyber-physical systems

Abstract

Abstract An actual task is to project a cyber and physical system (CPS) of industrial purpose based on a set of graphs and analytical models which describe the CPS behavior in the physical device level and in the virtual level. There is a scheme and description of CPS functionality principle as an automatic control digital system. The advantages of subtractive equations to describe a CPS are described and also the restrictions to use automatic models to synthesize the systems of higher order (digital production). There is a scheme and CPS functionality principle as a company cloud environment element is described (digital twin) which is based on a uml-diagram. There are advantages and disadvantages to describe a CPS with a uml-diagram given when they model CPS behavior as a part of digital production. There is a scheme given and CPS functionality principle is described using a Petri net model. It is clear that all three types of CPS description must be viewed together as a poly-model division which helps the CPS designers to create and research the project solutions of the Industry 4.0 digital production components synthesis.
