A digital twin is a virtual model of a physical (or “real-world”) asset, such as a process, product, service, or an individual. This pairing of the virtual and physical worlds allows us to simulate, analyze, control, improve, and predict the behavior and the issues of a system.
As strategic components of the so-called Industry 4.0, digital twins are an essential topic for research, because they are not single objects or monolithic data models, but include different aspects of digital representations, functionalities, models, interfaces, and more.
