Optimal Digital Twin Model-based CPS (Cyber Physical System) Design for Smart Factory

Recently, with the development of the Internet of Things and Artificial Intelligence technology, research and application cases that collect and analyze data in real-time in various fields such as manufacturing and smart city to optimize for real-world problems are increasing. Representatively, a virtual physical system or digital twin technology that supports real-time synchronization in both directions with the virtual world digitized from the real world is attracting attention. In this paper, we intend to design a system that defines a digital twin, operates with the same functions as real-world objects in a virtual environment and maintains and manages state information to compose virtual digital twin objects that are visible to users.
