First of all, from the smallest level - the enterprise point of view, industrial big data for the whole process of enterprise design, innovation, production, operation, management, decision-making services, for the enterprise's development strategy and the realization of the goal.

The second level, industrial big data serves the optimization of the supply chain, the improvement of the industrial chain, and the formation and optimization of the ecological chain. From the viewpoint of supply chain, industrial chain, and ecological chain, whether it is the production circle of CSM, the supply chain of a specific product manufacturing process, or the analysis of a complete production process, industrial big data is for its formation and optimization.

The third level, industrial big data to meet the actual needs of the industry and macroeconomic decision-making and regulation, to improve the quality of the industry and macroeconomic management decisions, ability. The government's industry management for the supply chain, industrial chain, ecological chain, business chain, value chain has a very important role, but the government's macro-control beyond such a chain itself, we have to respond to the major issues facing economic development, and even answer the manufacturing industry how to deal with such issues. So from the industry to see the important thing is the industry development strategy, and to the macro-control, not only from the industry's development strategy, but also from the whole economic development to see how these problems can be solved? This requires information.

Fourth, from the industrial transformation and upgrading of the demand, industrial big data is in order to one enterprise, industry, equipment, process, production line, supply chain transformation and upgrading services. Advanced manufacturing, industry 4.0, intelligent manufacturing, focusing on the integration of dualization and intelligent manufacturing of Made in China 2025, are the future direction of industrial transformation and upgrading mode. It turns out that our 3.0 industry, is the equipment and production line as the core of the automation, and 4.0 intelligent is the combination of these two process automation and data automation together.

↙ Big Data is the basis for building digital factories, and digital factories are a prerequisite for smart manufacturing!
