Smart factories rely on machines to work and interpret data, which can not only integrate customers and business partners, but also manufacture and assemble customized products. But people are still the core of manufacturing, and their functions are mainly control, programming and maintenance. The goal of smart factories is not to have no people, but to make people's work more valuable. Machines in smart factories do not replace people, but better assist people to finish their work. Taking WSI and Ti Ying's smart factory solutions as an example, relying on the maintenance of the Internet and using the factory management system can help enterprises to build an intelligent management platform, improve production efficiency, increase productivity, avoid mistakes, enlarge management power, and help enterprises realize the standardization and intelligence of processes through fast and intelligent working methods.
