This article mainly introduces what functions the mes system has, which has certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let Xiaobian take you to understand it together.

The seven functions of mes system are: 1. warehouse management;2. production scheduling;3. manufacturing process management;4. quality management;5. equipment tooling management;6. document management;7. material batch tracking.

I. Warehouse management

Sub-raw material bar code printing, raw material warehousing, production picking, production return.

1. Raw material barcode printing: For raw materials with batch tracking requirements, after the raw materials are received and qualified by QC inspection, the materials are divided into minimum packages, and the tracking barcode is printed and pasted on the minimum package to establish the association relationship between the raw materials and the manufacturer barcode, manufacturer batch, environmental protection raw materials, receipt date and other information.

2. Raw material warehousing: scan bar code and track raw materials. Enter quantity, create corresponding receipt document, record material receipt person, receipt time, and complete receipt of raw materials.

3, production picking: according to the production plan notice, open the picking list, warehouse keeper in advance nesting (including semi-finished products) ready, put in the warehouse area. In actual material issuing, import the material issuing list of the production work order in SAP into the system, and the warehouse keeper issues materials according to the work order. When issuing materials, scan the tracking bar code of raw materials and establish the corresponding relationship between work order and raw materials and semi-finished products. The system proofreads the bar code and quantity of raw materials during the process of issuing materials to prevent the occurrence of wrong materials, missing materials, over-receiving, under-receiving, etc.

4, production return: after the completion of work order processing, according to the work order will be the remaining raw materials returned to the warehouse processing. After the work order is returned to the warehouse, you can perform variance analysis on the raw material consumption of the work order in the system to analyze whether there is material over-loss or loss.

II. Production scheduling

SAP makes monthly plans, but SAP plans belong to high-level plans, and it is impossible to schedule the production of specific production orders among various processes. MES system production scheduling management module can use automatic scheduling and manual scheduling to schedule production orders, arrange the specific production line body, planned start time and planned end time of each work order in each process, and check the availability of materials such as complete sets according to the warehouse raw material inventory information provided by the warehouse management module. After the scheduling is completed, through the release of scheduling results, each authorized position and role can immediately query the scheduling information in the system, and arrange the work of the position under jurisdiction according to the scheduling content.

III. Manufacturing Process Management

After the job is scheduled and released by the planner, it has been determined that each job will be processed at which time and on which line at which operation. MES instructs material personnel and warehouse managers to pick, prepare and load materials in time, and also instructs on-site coordination production personnel to debug equipment and guide barcode printing personnel to print product barcodes required by work orders for production. And through the work order and document management system in the corresponding work instructions to guide the smooth progress of production.

During the production process, MES collects the processing and quality information in the production process in real time with information carriers such as bar code and RFID. At the same time, the collected information is mutually verified with the information of work order, process route and parameters, materials and quality, which plays the role of material error prevention, process error prevention and leakage prevention, and process error prevention. Meanwhile, the collected production and quality information is fed back to each Kanban, SPC and statistical report of the system in real time. Make the manager grasp the material, production progress and quality of workshop in the first time, and provide data support for the manager's decision.

IV. Quality Management

Define processes and criteria for quality activities in MES.

Quality information is measured and collected during manufacturing.

Control quality and business processes according to criteria.

Through SPC, SQC analysis of quality problems caused by the root causes, found that the trend of defects.

Find ways to prevent problems from happening in the future and improve processes.

V. Equipment tooling management

Comprehensive records of equipment daily maintenance, maintenance records, online analysis of fault records, equipment files, technical data, resume and other information easy to use. Improve equipment utilization, life, maintenance costs, energy consumption and safety in all aspects.

Through the classification and summary of maintenance and repair records, summarize the rules, reduce the on-site inspection of maintenance personnel, and focus on predictive maintenance.

Through information such as operation collection and equipment control, the operation status of the equipment is dynamically recorded, so that the production management personnel can timely control the operation status and capacity of the production equipment, reasonably arrange the production, timely dispatch, ensure that the production equipment is in the best state, and the production is smooth, orderly, high-yield and low-consumption.

VI. Document Management

Document management controls, manages and transmits information documents related to production units, including engineering drawings, standard process specifications, NC machining programs, etc.

The document control module sends various instructions to the operation layer, including providing operation data to the operator or providing production guidance to the equipment control layer.

Document management specification, identification of documents used in the work of the source, but also to ensure the correctness of the version. Increase the security and timeliness of document review and revision. It also reduces the cost of using paper.

VII. Material batch tracking

The realization of material batch tracking is based on the data collected in each link of the production process and completed through the organization of the system. These links include: incoming and outgoing of materials, SMT, plug-in, assembly, assembly and other processes involving the use of materials and parts.

Thank you for reading this article carefully. I hope that the article "What are the functions of mes system" shared by Xiaobian will be helpful to everyone. At the same time, I hope that everyone will support you a lot and pay attention to the industry information channel. More relevant knowledge is waiting for you to learn!
