Optimizing the Dependability of Cyber-Physical Systems Using Digital Twinning

Today's digital society integrates all processes of industrial and social life through the Internet of Things (IoT) under Networking and Web standards, using edge and fog cloud computing tools, methods, and best practices. The development of intelligent, self-adaptive systems, with applications in all areas of life, including the simulation of virtual communities, has increased the role of digital systems that simulate physical systems and behaviors. The digital twinning approach can significantly transform the performance and reliability of products or services. By creating virtual models of cyber-physical systems (CPS), engineers can simulate their behavior under various conditions, including failure scenarios. This simulation enables early identification of vulnerable components and root causes of problems, facilitating the development of effective prevention strategies. In this work, the aim is to describe a framework for designing a highly dependable CPS based on digital twinning when addressing Industry 4.0 paradigm.
