Abstract The Industry 4.0 technologies oriented for the modern industry as an application to solve the cyber-physical production control general task are viewed. A task to control is positioned as a hierarchy, which require some special schemes cyber-physical systems interaction organization to be developed. The control task hierarchy is converted to the control means hierarchy, within which they preserve the cyber-physical systems groups coordination unity organized in the company functional divisions in structure principle with variable equipment consistency. Information and functional cyber-physical systems interconnection are proposed to be defined within the technical architecture providing cyber-physical production complex automatizing. In the control system they underline the information component realizing not only calculation functions measuring but also net communication. Controlling and being controlled cyber-physical systems are proposed to be united into structures actively interacting with functional company divisions into closed automatic loops working out information and signal actions. There is a cyber-physical production hierarchy structure example given based on control processes tides formalized in physical and virtual levels. There is a cyber-physical systems matrix control model given to coordinate calculations, communications and industrial automatics functionality.

Controllers are devices regulating the operation of other devices or systems. Fuzzy controllers analyze the input data in terms of variables which take on continuous values in the interval [0, 1]. Since fuzzy logic has the advantage of expressing the solution of the problems in the natural language, the use of fuzzy instead of traditional controllers makes easier the mechanization of tasks that have been already successfully performed by humans. In the present paper a theoretical fuzzy control model is developed for the braking system of autonomous vehicles, which are included among the most characteristic examples of Cyber-Physical Systems. For this, a simple geometric approach is followed using triangular fuzzy numbers as the basic tools.

Damit cyber-physische Systeme einen Nutzen haben und echten Gewinn bringen, muss der Diskurs über eine rein technische Fragestellung hinaus erweitert und die Gestaltung der Zusammenarbeit von Mensch und Technologie stärker in den Fokus gerückt werden. Insbesondere in der Produktionssteuerung ist eine effektive und effiziente Kombination von Erfahrungswissen, menschlichen kognitiven Fähigkeiten sowie datengetriebenen technologischen Anwendungen von besonderer Bedeutung.   To benefit from implementing cyber-physical systems the discussion about technical solution has to be extended and more focused on the cooperation between human employees and technical applications. Especially in production control it is of particular importance to efficiently and effectively combine expert knowledge, human cognitive capabilities and data-driven technological applications. The article identifies challenges for developing suitable forms of cooperation.

Industrial revolutions have long since been mandatory for humanity in order to adapt to the age and innovations, resulting in the search of new ways to sustain productivity. Regardless of the line of business or the historical background of a sector, the concept of industrial revolution underlies the historical development of all sectors. The main reason is that production sustainability occurs when humanity presents their products at the same time announcing them. Consequently, new ideas, creations and revolutions can develop. Based on this, the first Industrial Revolution developed as a direct result of mechanisation while the Second Industrial Revolution developed as a result of electricity, and the Third Industrial Revolution developed as a direct result of computerisation. Nowadays, the Fourth Industrial Revolution aims to transform Internet of Things and Internet of Services into production. In the near future, enterprises will adapt to these innovations and hence improve their technologies, managerial and organisational perceptions, administrative levels, decision-making and logistic systems, as well as production facilities by means of developing global networks as part of Cyber-Physical Systems. Thanks to Cyber-Physical Systems, enterprises will carry out information production, control function, smart machines and storage systems independently within the production environment. This system will provide a rapid development of concepts like production, engineering, material procurement, industrial processes, supply chain, and life-cycle systems. Therefore, the aim of the present study is to theoretically analyse how managerial and organisational perceptions of enterprises undergo changes following the adoption of Industry 4.0 using literature review, which is defined as second-hand data, and to discuss the issues considering the restructuring of management-organisation of enterprises in accordance with this developing trend.

The cyber-physical systems (CPS) are large-scale intelligent complex systems by the deep integration of technology and the physical systems. The cyber-physical power systems (CPPS) are the key technology to implement the objective of smart grids, by seamlessly integrating the computing, communication and sensing technologies with the power system. The existing research of CPPS is limited to the survey. This paper firstly presents the concept of smart power object applied to CPPS, which often is a power device object adopts RFID technology to identify itself, feeds back its real-time states, and has certain coordination ability. Then, on this basis, the key technical problems of global optimization and local control based on CPPS is further studied, such as control model, construction strategy, coordination control mechanisms, and communication mechanisms. Finally, it is applied to regional voltage optimization control to implement smart optimization control in low voltage power system.

The recent proliferation of embedded cyber components in modern physical systems [1] has generated a variety of new security risks which threaten not only cyberspace, but our physical environment as well. Whereas earlier security threats resided primarily in cyberspace, the increasing marriage of digital technology with mechanical systems in cyber-physical systems (CPS), suggests the need for more advanced generalized CPS security measures. To address this problem, in this paper we consider the first step toward an improved security model: detecting the security attack. Using logical truth tables, we have developed a generalized algorithm for intrusion detection in CPS for systems which can be defined over discrete set of valued states. Additionally, a robustness algorithm is given which determines the level of security of a discrete-valued CPS against varying combinations of multiple signal alterations. These algorithms, when coupled with encryption keys which disallow multiple signal alteration, provide for a generalized security methodology for both cyber-security and cyber-physical systems.
