What are the main functions of the MES system?

MES core function 1: data collection: The data acquisition system of MES system is very flexible, and can also seamlessly connect with common ERP systems on the market (including SAP, Oracle, UFIDA, Kingdee, Ding Jie, etc.).

The data acquisition technology of the MES system is also very mature.

Such as barcode collection, product batch number, material batch number, processing resource number, transportation resource number, personnel number, abnormal category, abnormal phenomenon, equipment status (repair, maintenance, shutdown, etc.) ), job start, job end, and so on. For example, the product certificate information can be made into the first collection, and the full amount of data can be obtained by simply scanning the code.

The second core function of the MES system: production monitoring: the "black box" of traditional factory management in the manufacturing industry covers the eyes of the management.

The MES system realizes the visualization of production progress by tracking work-in-progress, monitoring output, monitoring raw materials and parts in the production process, monitoring the accuracy and operation of equipment, monitoring key production processes, monitoring production-related documents, etc. In order to detect problems in the production process in time, and immediately give warnings and adjustments.

MES core function three: process management: In the traditional manufacturing industry, process data is still manually entered into paper documents, which is not only easy to lose, but also not conducive to the confidentiality of process information.

When there is an exception in production, it is difficult to change the process, resulting in problems in production. The process management module of the MES system enters all production processes into the system and gives employees different levels of authority.

Employees with the corresponding permissions only need to change the system files, which is easy to operate, and the leakage of effective information is prevented. The process information management of the MES system combines the entered process with production tasks, product technical documents, and workshop resource information, and communicates them to front-line workers quickly and effectively, so as to better guide employees to complete production tasks.

Manufacturing Execution Systems(MES Manufacturing Execution System) is a management information system for the workshop level between the upper planning management system and the underlying industrial control. As early as 1990, the American Advanced Manufacturing Research Association (AMR) strictly defined it and proposed the MES three-layer structure integration modela managerial and structured planning layer; The executive layer that dynamically manages and controls the implementation of production plans and production processes; The control layer that controls the state of the device.

MES is a set of production information management system for the executive layer of the workshop of manufacturing enterprises, which can comprehensively monitor the production workshop from six aspects: "man-machine-material method and environmental testing".

peopleEmployee management, MES system can help enterprises save labor costs in actual production.

machineAs an important tool for enterprise production, the MES system can control the equipment and control the equipment in real time.

materialRealize error-proof management such as misloading and missing installation of materials at the station, so that there is no stacking, no shortage of materials, and no good materials.

Act: Implement standard process instructions for production.

Rings: Realize the closed loop of quality management.

6. Measurement: control the quality of the final product.

At the same time, the MES system has the following advantages:

Increase personnel productivity

Effectively connect the management and the workshop execution layer to form a closed-loop system of production planning from designation, release, execution to feedback and control, and improve production efficiency.

Increase equipment uptime

Through the MES system to the equipment data analysis and early warning, through the equipment andon the real-time impact, reasonable planning of maintenance, spot inspection plan, timely correction and adjustment, improve equipment utilization.

Improve the product qualification rate

Through visual guidance of production, a large number of error-proofing instructions, and strict guarantee of the production of non-receiving, non-manufacturing, and non-transmission of the three principles of production. By collecting the execution data of each production equipment in real time, we can find out the key to quality problems, and adjust the process in time to effectively improve the product qualification rate.

Reduce data aggregation and analysis time

Open up the information island of the enterprise, summarize and present the data of quality, cost, delivery and employees, and improve the transparency of production.

Reduce paper usage

Truly realize paperless office and reduce the risk of omissions and errors in information transmission.

At present, the MES system has been applied to many aspects of production, and KLCII MES has also been continuously superimposed and summarized in the process of this application.

Production controlThrough intelligent production control, the standard deviation is reduced to ensure the continuous stability of production and the timeliness of linkage processing.

Process optimizationIn terms of production process optimization and collaborative error prevention, production costs can be reduced to the greatest extent.

Quality traceabilityFocusing on the product pedigree, the monitoring and analysis of the data quality of the production process is constructed, which can control the quality accuracy in real time and achieve accurate traceability.

Asset managementReal-time coverage and monitoring of assets and equipment to ensure reliable operation of assets and equipment and reduce downtime and maintenance.

The main function of the MES system is to integrate the integrated management of the production site, with equipment management, quality management, production planning, data collection and other original relatively independent software systems. This has a certain inheritance of the information architecture. The overall optimization of the new core cloud MES system in use greatly helps enterprises implement full closed-loop production.

The main functions of the MES system:

1. Optimize the implementation mode of on-site production management of enterprises;

2. Strengthen the ability of collaborative management between various production departments;

3. Improve the timeliness and accuracy of the production process;

4. Provide effective and standardized support for the quality inspection of products, intermediate products and raw materials of enterprises;

5. Real-time grasp of planning, scheduling, quality status, etc.

The function of MES can be boiled down to:

1. Optimize the implementation mode of on-site production management of the enterprise, change from human handwriting to computer scanning, which is fast and accurate, strengthens the control of the production process, and achieves the purpose of refined management.

2. Strengthen the ability of collaborative management between various production departments, from the past manual statistical release to electronic kanban management, automatic collection, automatic release, greatly improve work efficiency and reduce costs.

3. To improve the timeliness and accuracy of the production process, in the past, on-site management could only be judged by day when it was fast, but now it can be judged by hour or even by second.

4. Provide effective and standardized support for the quality inspection of products, intermediate products and raw materials of enterprises;

5. Real-time grasp of the information status of planning, scheduling, quality, process, equipment operation, etc., so that the on-site production process is completely transparent, so that the relevant departments can find and solve problems in time.

6. The linkage and interaction of MES and ERP enable the upper management institutions and decision-makers to understand the problems and progress in the production implementation process in a timely manner, so that the upper decision-makers can better understand the facts, and even it is necessary to make corresponding adjustments and changes to the ERP plan, and can also make amendments or changes to the MES process.

7. Due to the continuous development of Internet technology, the production of production institutions in different regions and even the world can be seen at a glance, and the overall activity benefits of the enterprise can be seen clearly and clearly.

The MES system is a set of production information management system for the executive layer of the workshop of manufacturing enterprises. MES can provide enterprises with management modules including manufacturing data management, planning and adjustment management, production scheduling management, inventory management, quality management, human resource management, work center equipment management, tool management, procurement management, cost management, project kanban management, production process control, underlying data integration and analysis, upper data integration and decomposition, etc., to build a solid, reliable, comprehensive and feasible manufacturing collaborative management platform for enterprises. Traditional MES can be broadly divided into two categories:

1) Dedicated MES. It is primarily a system developed for domain-specific problems such as shop floor maintenance, production monitoring, finite capacity scheduling, or SCADA. 2) Integrated Manufacturing Execution System.

Initially, such systems were designed for a specific standardized environment, but have now expanded to many fields such as aerospace, assembly, semiconductors, food, and hygiene. It is functionally integrated with transaction processing at the upper level and real-time control systems at the lower level. Morning God.

Each functional module of the MES system provides a gradual transition from the monitoring process of the underlying close to the automation system to the management layer of cost management, which can meet the requirements of enterprises in different planning stages in the field of information production management, and realize the smooth transition and gradual improvement of the information process on the basis of inheritance. The specific functions are as follows:

1) Plant modeling and basic data settings.

At the heart of the MES system platform is a factory modeling environment that combines different application functions to define the execution logic. According to the physical model (actual equipment, area, etc.) and logical model (business process), the factory model is created based on the factory model level to provide basic data support for the business module.

2) Production management.

Under the guidance of the production plan, the production management of the MES system organizes and coordinates production according to the characteristics of the production process of various industries, tracks the production process data, and assesses various production indicators. And through data analysis, the production process is optimized. Realize the preparation and tracking of plans, the analysis of production data and the assessment management.

3) Production process monitoring and production performance feedback.

The production process monitoring of the MES system focuses on the monitoring of material transportation and quality indicators between the production process and the technological process. When the production process monitoring system finds an abnormality, it can make an alarm according to the pre-set settings. Help the production command and dispatch department of the enterprise to carry out production coordination and reasonable scheduling, and improve the rapid response ability of production.

4) Quality management.

According to the quality inspection standards, the MES system collects quality data from the automation system of the production site in real time, when it is found that there are quality problems in the production process, the system generates an abnormal quality alarm, and the production management personnel find the key process links or key quality personnel according to the quality control network, reduce the analysis process of quality problems, speed up the processing of quality abnormalities, improve the quality awareness of all employees, and ensure product quality.

5) Material management.

The MES system can realize the function of product backtracking and forward-traceability. For the item batch of the final product, you can query which batches of raw materials, intermediate materials, and quantities and characteristics of the item were used. For batches of raw materials, you can query which end products use the batch of materials.

6) Cost management.

The MES system can establish a criss-crossing cost control network with the centralized management of functional departments and operation areas as the key link, and the main control process as the station, so as to realize a full range of cost data analysis and management, provide various reports, queries, and intuitive charts and graphs for comparative analysis of various cost data, and save historical data.

7) Reporting system.

The report system is the output data of MES systems, and it is also the data interface between systems, which is an important means of data source integration, and the report covers all the business contents of MES system, including scheduling, equipment, quality, materials, process indicators, etc. The data source mainly comes from the MES database, and the database fields are reorganized into user-facing objects through the semantic layer, and the report function is realized on this basis.

If you want to know what an MES system is, you can start with the background in which it was generated. In general, the production and operation management process of an enterprise can be divided into three layersThey are the planning layer, the execution layer, and the control layer

Through the planning layer management (ERP, MRP, etc.) system, the enterprise integrates the existing production resources of the enterprise according to customer demand, inventory and market **, etc., and prepares the production plan; According to the production plan issued by the planning layer, the executive layer formulates the workshop operation plan, arranges the processing tasks of the control layer, and summarizes and reports the operation plan and task execution. The production process of the whole factory is not transparent, when the production plan changes, material shortages, equipment failures, processing quality seepage and other problems, the information can not be effectively transmitted, and the production can not be adjusted and optimized in time.

In order to make up for the information fault phenomenon between the planning layer and the control layer, the control layer MES came into being, MES for real-time monitoring of production information, upward transmission to the planning layer, downward to the executive layer of control, the upper production planning system of the enterprise and the lower level of the workshop equipment control system linkedIt fills the gap between the upper and lower levels, opens up the factory information channel, and makes it the basis and necessary condition for realizing the "upgraded version" of industrial manufacturing.

MES system core function 1: data acquisition: MES system data acquisition system is very flexible, and can also be seamlessly connected with common ERP systems on the market (including SAP, including:

SAP, Oracle, UFIDA, Jindee, Dingjie, etc.). The data acquisition technology of the MES system is also very mature.

For example, barcode collection, product batch number, material batch number, processing resource number, transportation resource number, personnel number, abnormal category, abnormal phenomenon, equipment status (repair, maintenance, fault shutdown, etc.), operation start, operation end, etc. For example, the product certificate information can be collected, and the full data of production can be obtained by simply scanning the code.

MES system core function two: production monitoring: the traditional manufacturing factory management "black box", covering the eyes of the management, MES system through the tracking of work-in-progress, the monitoring of output, the monitoring of raw materials and parts in the production process, the accuracy and operation of the equipment monitoring, the monitoring of key production processes, the monitoring of production-related documents, etc., to achieve the visualization of production progress, so as to facilitate the timely discovery of problems in the production process, instant warning and adjustment.

The core function of the MES system is three: process management: the traditional manufacturing industry, the entry of process data or stay in the way of manual entry of paper documents, which is not only easy to lose, but also unfavorable to the confidentiality of process information.

The process management module of the MES system enters all production processes into the system, and opens different levels of authority for employees.

Employees with corresponding permissions can only change the system files, which is easy to operate and prevents effective information leakage. The process information management of the MES system combines the entered process with production tasks, product technical documents and workshop resource information, and conveys them to front-line workers quickly and effectively, so as to better guide employees to complete production tasks.
