1, workshop resource management of MES system
Workshop resources are the basis of workshop manufacturing and MES system operation. Workshop resource management is mainly to manage workshop personnel, equipment, tooling, materials, working hours, etc., to ensure normal production, and to provide historical records and real-time status information of resource use.
2. Inventory management of 2.MES system
Warehouse management is used to manage all stored materials in the workshop. Workshop materials include self-made parts, purchased parts, purchased parts, tools, tooling and revolving raw materials. Its functions include: querying the materials stored in the warehouse through inventory management, and querying the current inventory situation and history; Provide inventory counting and warehouse distribution functions, and set an alarm when raw materials, tools and tooling are insufficient; Provide warehousing operations for warehouse parts, including borrowing, returning, repairing and scrapping tools/tooling.
3, MES system production process management
Production process management realizes closed-loop visual control of production process to reduce the waste of waiting time, inventory and overproduction. In the production process, the bar code, touch screen and machine tool data acquisition are used to track the planned production progress in real time. The purpose of production process management is to control production, implement and execute production scheduling, track the status of work and workpieces in the workshop, and outsource the processes that cannot be processed at present. It can realize management functions such as process scheduling, out-of-process coordination and alignment, and can display workshop site information and task progress information in real time through kanban.
4, MES system production task management
Production task management includes production task receiving and management, task progress display and task query. Provide all project information, query the designated project, and show the whole production cycle and completion of the project. Provide production progress display, display tasks of today, this week and this month by day, week and month, divide tasks by color, and track project tasks.
5, MES system workshop planning and scheduling management
Production planning is the key and difficult point of workshop production management. Improving the scheduling efficiency of planners and the accuracy of production planning is an important means to optimize the production process and improve the production management level.
The workshop receives the master production plan and makes a reasonable production and processing plan according to the current production situation (capacity, production preparation and ongoing tasks, etc.). ), production preparation conditions (drawings, tooling, materials, etc.). ), as well as the priority and planned completion time of the project, and monitor the production progress and implementation status.
Advanced scheduling tool (APS system) combines the real-time load of workshop resources and the implementation progress of existing plans to form an optimized detailed scheduling plan after capacity balance. It fully considers the processing capacity of each device and adjusts it at any time according to the actual situation on site. After the automatic scheduling is completed, plan evaluation and manual adjustment are carried out. In the small batch, multi-variety and multi-process production environment, the use of advanced scheduling tools can quickly deal with the complex situation of emergency plugging.
6. Material tracking management in 6.MES system
Manage and track the logistics in the production process through bar code technology. In the production process, the online status of materials is tracked by bar code scanning, and the material circulation process is monitored to ensure the rapid and efficient circulation of materials in the workshop production process, and can be queried at any time.
7, MES system quality process management
Process inspection and product quality management in manufacturing process can realize the traceability of process inspection and product quality process, and strictly control unqualified products and rectification process. Its functions include: to achieve a comprehensive record of key elements in the production process and complete quality traceability, accurately count the qualified rate and unqualified rate of products, and provide quantitative indicators for quality improvement. According to the product quality analysis results, preventive maintenance is carried out on the ex-factory products.
8, MES system production monitoring management
Production monitoring can monitor the production process from multiple dimensions such as production progress and equipment operation, manage the alarm information in the workshop, including the alarm information of equipment failure, personnel absence, quality and other reasons, find problems in time, report them and deal with them, so as to ensure the smooth progress and control of the production process. Combined with distributed numerical control DNC system and MDC system, equipment networking and data acquisition are carried out. Realize equipment monitoring and improve the utilization rate of bottleneck equipment.
9. Statistical analysis of 9.MES system
The data generated in the production process can be statistically queried and analyzed to form a report to provide reference data and decision support for the follow-up work. There are abundant data in the production process, and the system can customize different statistical query functions according to needs, including: product processing progress query; Shop WIP query; Workshop and workstation task query; Complete set of product matching query; Quality statistical analysis; Utilization ratio analysis of workshop capacity (manpower and equipment); Statistical analysis of scrap rate/defective rate, etc.
