Yunxin MES system takes the data integration of the entire workshop as the core and production tracking as the main line, and comprehensively controls the workshop production business such as production planning management, process flow management, material management, resource management, logistics management, quality management, equipment management, test interface management, production work order management, data collection, statistical analysis, automatic alarm (early warning), etc. Yunxin MES system is a complex and large production management system, which manages the production process meticulously through numerous functional modules. However, each manufacturing enterprise often hopes to adopt the strategy of "small steps and slow running, step-by-step implementation" according to its own scale or production characteristics. In order to adapt to market demand, Yunxin MES system has been designed in a modular way to reduce the degree of coupling between modules, and can be implemented gradually in a flexible expansion manner. The MES system grows with the enterprise, thereby reducing the implementation risk, implementation difficulty and cost of the project.
