The concept of digital twins was first proposed by the Air Force Research Laboratory in a speech in March 2011. As its name implies, it uses digital technology to create a mirror world that is symmetrical to the real world. In the process of production, it can be used in the fields of product development, production management, equipment management, and help enterprises to carry out simulation testing, verification, production scheduling, adjustment and optimization, as well as simulation of mechanical and electrical linkage simulation. To a large extent, digital twins can help companies collaborate and model optimization in a low-cost mirrored world, providing more solutions to real-world factories.
Digital twins can help enterprises find problems in product, equipment and production management before realizing production, optimize the whole production process, improve product quality, help enterprises improve production efficiency, and finally achieve efficient flexible production.
