Timerelated Constraints in Administration Shell Design within Cyberphysical Production Systems The concept of Cyberphysical Production System has recently emerged. It emphasizes the expected and very close connection between industrial software systems and production assets on the next generation of intelligent industrial systems. The cyberphysical conceptualization hints at assets making their functions available through the so called administration shells. These are software structural design tenets that from, a functional perspective, will not only incorporate software interfacing aspects but also autonomous behaviour. There is an important body of practice in what is now perceived as cyberphysical integration. However, such work has taken a somehow informal approach to formalizing system engineering aspects and in particular to the impact of timerelated constraints affecting, the design locally and, the CPPS as a whole. This paper provides a model that relates physical, logical and computational aspects of cyberphysical design from structural and behavioural perspectives. Its goal is to provide a starting point for designing cyberphysical components while supporting informed decision making in respect to software design, integration and deployment practices that enable these components to operate in cyberphysical synchronization.

Cyber Physical Production Systems: A Review of Design and Implementation Approaches Cyber Physical System (CPS) is a very crucial and promising technology in Industry 4.0 context. The application of CPS in the production and manufacturing environment gave rise to the term Cyber Physical Production Systems (CPPSs). CPPSs hold great potential to make production systems become intelligent, resilient and selfadaptive by utilizing the cyber world to realize the distributed collaboration in the physical world. There is growing interest in CPPSs, yet there is a scarcity of review to document the current status of CPPSs. This review aims to classify the current research activities within CPPSs field with a special focus on design and implementation approaches in view of industrial engineering and to analyze research gaps based on the literature review. Findings of this review can be used as the basis for future research in CPPSs and related topics.
