What are the seven major functions of the mes system?

The seven major functions of the mes system are: 1. Warehouse management; 2. Production scheduling; 3. Manufacturing process management; 4. Quality management; 5. Equipment and tooling management; 6. Document management; 7. Material batching times tracking.

1. Warehouse management

is divided into raw material barcode printing, raw material warehousing, production picking, and production returning.

1. Raw material barcode printing: For raw materials with batch tracking requirements, after the raw materials are received and passed the QC inspection, the materials will be divided into the smallest packages, the tracking barcode will be printed and pasted on the smallest package. Establish the relationship between raw materials and manufacturer barcodes, manufacturer batches, whether environmentally friendly raw materials, receipt date and other information.

2. Raw material storage: scan the barcode to track the raw materials. Enter the quantity, create the corresponding warehousing order, record the person who put the materials into the warehouse, the time of warehousing, and the raw materials are completed.

3. Production picking: According to the production plan notification, a picking list is issued, and the warehouse keeper prepares the materials (including semi-finished products) in advance and places them in the distribution warehouse area. When actually issuing materials, the material issue list of the production work order in SAP is imported into the system, and the warehouse manager issues materials according to the work order. When issuing materials, scan the raw material tracking barcode to establish the corresponding relationship between work orders, raw materials, and semi-finished products. During the issuance process, the system checks the barcodes and quantities of raw materials to prevent incorrect materials, missing materials, over-receipts, under-receipts, etc.

4. Production return: After the work order is processed, the remaining raw materials will be returned to the warehouse according to the work order. After the return of the work order is completed, the raw material consumption of the work order can be differentially analyzed in the system to analyze whether there is excessive damage or loss of materials.

2. Production Scheduling

A monthly plan is formulated in SAP, but the SAP plan is a high-level plan and cannot schedule the production of specific production work orders between various processes. The production scheduling management module of the MES system can use automatic production scheduling and manual production scheduling to schedule production work orders, arrange the specific production line body, planned start time and planned end time of each work order in each process, and according to the warehouse management module Provide warehouse raw material inventory information and conduct availability checks such as complete materials. After the production scheduling is completed, through the release of the production scheduling results, each authorized position and role can immediately query the production scheduling information in the system, and arrange the work of the jurisdictional position according to the production scheduling content.

3. Manufacturing process management

After the work order is scheduled and released by the planner, it has been determined when and on which line of which process each work order will be processed. MES guides material clerks and warehouse managers to pick, prepare and load materials in a timely manner. It also guides on-site production personnel to coordinate and debug equipment, and guides barcode printers to print product barcodes required for work orders and prepare for production. And guide the smooth progress of production through the corresponding work instructions in the work order and document management system.

During the production process, MES uses barcodes, RFID and other information carriers to collect processing and quality information in real time during the manufacturing process. While collecting, it combines the collected information with work orders, process paths and parameters. , materials, quality and other information for mutual verification, which plays the role of material error prevention, process error prevention and leakage prevention, and process error prevention. At the same time, the collected production and quality information is also fed back to various dashboards, SPC and statistical reports of the system in real time. In this way, managers can grasp the materials, production progress and quality situation of the workshop at the first time, and provide data support for managers' decision-making.

4. Quality Management

Define the processes and guidelines for quality activities in MES.

Measure and collect quality information during the manufacturing process.

Control quality and business processes according to guidelines.

Use SPC and SQC to analyze the root causes of quality problems and discover the trends that cause defects.

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

5. Equipment tooling management

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

By classifying and summarizing maintenance and repair records, we can summarize the rules, reduce on-site inspections by maintenance personnel, and focus on predictive maintenance.

Through job collection, equipment control and other information, the operating status of the equipment is dynamically recorded, so that production managers can promptly control the operating status and capabilities of the production equipment, reasonably arrange production, and timely dispatch to ensure that the production equipment is at its best In this state, production is carried out smoothly, orderly, with high yield and low consumption.

6. Document Management

Document management controls, manages and delivers information documents related to the production unit, including engineering drawings, standard process procedures, CNC processing procedures, etc.

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

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

7. Material batch tracking

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