Method for supervising production life cycle of product based on metadata and process management

The invention provides a method for supervising the production life cycle of a product based on metadata and process management, and relates to the technical field of software and production and manufacturing. The method for supervising the product production life cycle based on metadata and process management is composed of the following four parts: 1) a data model analysis rule and a coding rule; 2) defining metadata by software; (3) the software maps the production process into a flow chart for display and management according to the product technology or the production element content; and 4) binding the metadata and the flow chart and associating the follow-up change of the data acquired in the actual production field. According to the invention, the process or plan resource change is converted into the structured data in real time, the structured data is stored in the metadata system, the process model is automatically mapped and created through the metadata system, and specific production units are bou
