Description
Technical Field
The invention relates to the technical field of software and production and manufacturing, in particular to a method for supervising the production life cycle of a product based on metadata and flow management.
Background
Manufacturing process product data management system (Product Data Management, PDM system for short): it was proposed by OMG organization when published in 1997, 2. Prop. PDMenabaler standard draft. It is a software-based technology that manages all product-related information (including electronic documents, digitized files, database records, etc.) and all product-related processes (including workflows and altered flows). However, due to the large number of enterprise departments, different departments introduce different software management systems, such as resource management systems (ERP) and manufacturing management systems (MES) represented by manufacturers such as friends, butterflies, SAPs, etc., in implementing the digitizing process. In different systems, there is a problem of product management in the manufacturing process, that is, different departments use PDM system frames, but the PDM frame data used by different departments are not uniform in the description or definition mode of the same product or content in the same enterprise, so that the enterprise forms a data island, and the departments cannot be completely interconnected and intercommunicated with each other, which results in low operation efficiency of the enterprise and extremely high communication and debugging cost.
Business process management system (Business Process Management, BPM system for short): the standardized construction end-to-end excellent business process is used as a center, the simplest and direct flow chart is used as a model, and the enterprise business model is built on a system taking the process as a core. When an enterprise applies a business process management system, the business content of the enterprise corresponding to each process node needs to be customized, and a business model is drawn in a flow chart form conforming to Business Process Modeling (BPMN) through the association relation among the businesses (Business Process Model and Notation: OMG pushes out a BPMN2.0 standard in 2011, redefines the BPMN, and the main purpose of the BPMN is to provide a number of symbols which are easy to be understood by all business users, and the complete business process model is constructed from the business analysis of creating process outlines to the realization of the processes until the management and the monitoring of end users. It requires the user to model the model, define individual flow modules, and manually associate the defined flow modules. However, in a practical large-scale manufacturing enterprise, if the enterprise relies on manual work to perform business process modeling, the enterprise is required to have enough staff to know the business in each manufacturing field of the enterprise, and a large amount of manual business process modeling work is required to be performed by the staff, which is a task which is basically impossible to complete in the enterprise. Therefore, a method is needed that can automatically generate flow modeling by analyzing rules through the production of pre-elements or processes by an enterprise. This is also an advantage of the present invention in that the application maps the production process to a flow chart for presentation and management, depending on the product process or production element content.
In the actual production and manufacturing management process of enterprises, a waterfall model is often followed, namely: according to the order process department, defining the process rules and the manufacturing method, namely, planning to partially produce manufacturing resources, namely, warehouse and purchasing to solve the problem of insufficient resources, namely, after the resources are aligned, the production part starts to produce, namely, the production end quality part performs inspection, namely, warehouse entry, namely, delivery and archiving. However, after the traditional manufacturing industry follows the process to carry out production, emergency situations such as cancellation of orders in the middle, change of technological rules and manufacturing methods, change of plans and the like are frequently encountered, but a company does not acquire change information in urgent time because of information asymmetry among departments, so that the production and the manufacturing departments continue to manufacture to the end according to the original requirements, a plurality of finished products do not meet the new requirements, the rejection rate is increased, and the profit margin is reduced.

2) In a practical large-scale manufacturing enterprise, if the complicated production and operation activities depend on manual work to perform business process modeling, the enterprise is required to have enough personnel capable of knowing the business in each production and manufacturing field of the enterprise, and the personnel are required to perform a large amount of manual business process modeling work.
3) After the traditional manufacturing industry follows the process to carry out production, emergency situations such as order midway cancellation, process rules and manufacturing method change, plan change and the like are frequently encountered, but a company obtains change information when the production and manufacturing departments do not have emergency because of information asymmetry among departments, so that the production is continued to be finished according to the original requirements, a plurality of finished products do not meet the new requirements, and the problems of increased rejection rate and reduced profit rate are caused.
