The evolution of Digital Twins
Simulation technology such as the digital twin has actually been mature in the past, from simulating a single physical field, multi-physics field, and the whole system to drive the entire product development, and now simulating the entire product life cycle. In the past, traditional digital twins were limited, for example, they could not work on virtual and physical machines at the same time. However, digital twins have developed rapidly in the past two decades. They can not only visualize equipment but also collaboratively manage the life cycle and even optimize the entire manufacturing process which becomes the foundation to support the development of Industry 4.0.
