Industry 4.0 is a high-tech strategic program proposed by the German government. It is jointly funded by the German Federal Ministry of Education and Research and the Federal Ministry of Economics and Technology, with an estimated investment of 200 million euros. It aims to improve the intelligence level of the manufacturing industry, establish smart factories with adaptability, resource efficiency and human factors engineering, and integrate customers and business partners in business processes and value processes. The technological basis is networked physical systems and the Internet of Things (IoT).

Germany's so-called Industry4.0 refers to the use of the Internet of Things Information System (Cyber-PhysicalSystem or CPS) to supply, manufacture, and sell information in the production of data, intelligence, and finally to achieve a fast, effective, and personalized product supply.

The "Industry 4.0" project is divided into three main themes:

One is the "smart factory," which focuses on the study of intelligent production systems and processes, as well as the realization of networked and distributed production facilities;

The second is the "smart production," which is mainly concerned with the management of the production and logistics of the entire enterprise, the interaction between humans and machines, and the application of 3D technology in the industrial production process. technology in the industrial production process. The program will pay special attention to attracting the participation of small and medium-sized enterprises (SMEs) in an attempt to make SMEs the users and beneficiaries of a new generation of intelligent production technologies, as well as the creators and suppliers of advanced industrial production technologies;

Thirdly, it is the "intelligent logistics", which is mainly through the Internet, the Internet of Things (IoT), and the logistics network, integrating the logistics resources, and giving full play to the efficiency of the supply side of the existing logistics resources, and the demand side, the The demand side, on the other hand, is able to quickly obtain service matching and get logistics support.
