I. Introduction
Cyber-physical systems make the foundation for the realization of the concept of Industry 4.0, aiming the connection and communication between the physical and virtual components of the process management systems. These systems interact through sensors and actuators with the physical world, computing and networking elements allow them to function in the cyber space. Thus, physical processes in various sectors, e.g. education, healthcare, energy, transport, etc. can be fully automated, but also managed in an intelligent way, which leads to the emergence of many intelligent (smart) applications - smart schools, homes, offices, factories, cities [1], [2].
