Starting from the product design phase as the input and ending at the output to the service phase, the product manufacturing process is enhanced through the application of information technology, automation, big data simulation analysis, and other technical means. This improvement aims to increase the collaborative manufacturing capability among various digitalized workshops. It involves closed-loop, continuous optimization and enhancement of product quality, cost, energy efficiency, lead time, and more, while achieving a flexible, networked, intelligent, and predictive collaborative production mode.
