MES is a customizable manufacturing management system, and the process flow and management needs of different enterprises can be achieved through on-site definition.
Workshop resource management
Workshop resources are the basis of workshop manufacturing and production, and also the basis of MES operation. Workshop resource management mainly manages workshop personnel, equipment, tooling, materials and working hours, to ensure normal production, and to provide historical records and real-time status information of resource usage.
Production task management
Production task management includes functions such as production task reception and management, task progress display and task query. Provide all project information, query the specified project, and display all production cycle and completion status of the project. Provide production progress display, display the tasks of the day, week and month in daily, week and month, and distinguish the stages of the task by colors to track the project tasks.
workshop planning and production scheduling management
production plan is the key and difficulty of workshop production management. Improving the production efficiency of planners and the accuracy of production planning is an important means to optimize production processes and improve production management level.
workshop receives the main production plan, and reasonably formulates production and processing plans to supervise production progress and execution status based on the current production status (capacity, production preparation and in-process tasks, etc.), production preparation conditions (drawings, tooling and materials, etc.), as well as the priority level of the project and the planned completion time.
Advanced production scheduling tool (APS) combines the real-time load of workshop resources and the progress of existing plan execution, and after the capabilities are balanced, an optimized detailed production scheduling plan is formed.It fully takes into account the processing capacity of each equipment and adjusts it at any time according to the actual situation on site. After completing automatic delivery scheduling, plan assessment and manual adjustment are carried out. In small batch, multi-variety and multi-process production environments, advanced production scheduling tools can quickly deal with the complex situation of emergency order insertion.
Production process management
Production process management realizes closed-loop visual control of the production process to reduce waste such as waiting time, inventory and overproduction. During the production process, various methods such as barcodes, touch screens and machine tool data collection are used to track planned production progress in real time. Production process management aims to control production, implement and execute production scheduling , track the work and workpiece status in the workshop, and can be handled out of the process that currently does not have the ability to process. It realizes management functions such as process assignment, process outreach and complete sets, and can display workshop on-site information and task progress information in real time through the Kanban.
Quality process management
Process inspection and product quality management of the production process can realize process inspection and product quality process traceability, and strictly control the unqualified products and rectification process. Its functions include: achieving comprehensive recording of key elements of the production process and complete quality traceability, accurately counting the pass rate and failure rate of the product, and providing quantitative indicators for quality improvement. According to the results of for product quality analysis of , preventive maintenance of the factory products.
Production monitoring management
Production monitoring realizes monitoring of the production process from multiple dimensions such as production plan progress and equipment operation status, and realizes the management of workshop alarm information, including equipment failures, personnel absences, quality and other reasons alarm information, timely discover problems, report problems and handle problems, thereby ensuring the smooth progress and control of the production process. The distributed digital control DNC system and the MDC system are combined for device networking and data collection. Implement equipment monitoring and improve the utilization rate of bottleneck equipment.
Material Tracking Management
manages and tracks logistics in the production process through barcode technology. During the production process, the material is tracked through barcode scanning and monitoring the material flow process to ensure that the material flows quickly and efficiently during the workshop production process, and can be queried at any time.
Inventory Management
Warehouse Management manages all inventory materials in the workshop. The materials in the workshop include homemade parts, outsourced parts, purchased parts, knives, tooling and turnover raw materials. Its functions include: realizing the retrieval of warehouse storage materials through inventory management, querying current inventory status and historical records; providing inventory inventory and warehouse allocation functions, setting alarms when the inventory volume of raw materials, tools and tools is insufficient; providing warehouse parts entry and exit operations, including borrowing, return, repair and scrapping of tools/working.
Statistical analysis

The data during the production process is rich, and the system customizes different statistical query functions according to needs, including: product processing progress query; workshop product inquiry; workshop and work station task query; product supporting query; quality statistical analysis; workshop capacity (human and equipment) utilization analysis; scrap rate/defective rate statistical analysis, etc.
MES and other digital systems
Through the integration of MES, ERP system, PDM/process management (CAPP) system, CNC machine tool networking (DNC)/machine tool monitoring and data acquisition (MDC) system, it realizes full sharing and effective utilization of multi-level data from design/process, management and manufacturing.
ERP system uses the information obtained from the PDM/CAPP system to formulate the main production plan. The main production plan is passed to MES for workshop-level production scheduling and workshop production preparation. Information related to materials needs to be passed to the digital three-dimensional warehouse to guide warehouse management. The storage information of materials in digital three-dimensional warehouses and financial information are fed back to the ERP system to guide procurement and financial management.
MES After obtaining the main production plan and production preparation information such as materials, supply, procurement and inventory from the ERP system, it will conduct workshop planning and schedule production, and issue production tasks to the DNC system to arrange CNC processing, and issue inspection tasks to the quality system for quality tracking. At the same time, MES obtains information on task execution, processing, materials, working hours, equipment, tooling and personnel during the production process through the data acquisition system, and is used for production process monitoring and workshop event processing.
QMS obtains materials, structures, processes, tools and equipment from the CAPP system, and obtains production plans and other information from the ERP system. The obtained quality record , reports and correction information are feedback to PDM/CAPP/MES to guide the subsequent quality management process. And use digital detection and measuring instruments to monitor and analyze the detection information.
data acquisition and data analysis system uses the machine tool network automatic acquisition function provided by the DNC system and manual acquisition methods such as touch screen, scan gun , etc. to collect workshop data. These data are passed to the MES system for production monitoring, and quality-related information is passed to QMS for quality tracking, problem processing and statistical analysis.
Manufacturing technology based on network and informationization is one of the future development directions of advanced manufacturing technology. A digital workshop with MES as the core uses computer software, hardware and network environments to realize digital manufacturing of products, which can improve product manufacturing capabilities, shorten product manufacturing cycles, reduce manufacturing costs, and thus improve corporate competitiveness.
