What is manufacturing execution system (MES)?

In today’s competitive market, manufacturers are always trying to find ways to improve production efficiency to create a competitive advantage. How to maximize productivity while minimizing costs? When this problem was posed, the MES Factory Production Management System was born, and is increasingly becoming a trend that Vietnamese businesses are particularly interested in.

What is MES?

MES (Manufacturing Execution System) is a computer system that monitors the production area, control, logistics, product history throughout from input materials to finished products according to real time. MES is an integrated system that monitors many factors at the same time (materials, people, machines), manages product quality, optimizes production processes and improves business efficiency.

MES can be applied in many diverse manufacturing industries: apparel, electronics, chemicals, building materials,… especially in FMCG, food – beverage and health care industries.

In today’s digital transformation context, the MES is an intermediary between the Supervisory Control & Data Acquisition System (SCADA) and the Enterprise Resource Planning System (ERP) and the Enterprise Resource Planning System (ERP). Machine Automation Process Control (PLC) system. These systems all play an essential role in automating manufacturing industries, managing instant updates in the ongoing production process with digitized reports, replacing management. Post-production by manual report writing.

Why do businesses need MES systems?

The MES system is an inevitable trend of the manufacturing industries. The fierce competition in the global market makes it not enough to maintain stable production, but it is necessary to create its own competitive advantage. To do that, it is necessary to improve the ability to manage product lifecycle, data management, intelligent and optimal production management. Therefore, if your business is facing one of the common problems in production such as:

  • Delayed information, resulting in untimely processing,
  • Production interruptions, resulting in production of goods that are behind schedule or of poor quality,
  • Difficulty in innovating to catch up with market trends,
  • Time-consuming, risky, and error-prone due to manual processes and paperwork
  • Can not be managed visually, difficult to track because there are too many systems in the factory, discrete systems, not linked together,
  • Having problems in traceability, document tracing,

Maybe, your business needs a MES system.

Main functions of the MES system

Typically the functions of an MES system include:

Product Quality Management

  1. Product specification management
    The MES system stores product definitions and exchanges data with other information systems about standardized production rules, related documents, and certificates. This creates a unified information system to ensure that exactly what is produced meets the standardized specifications.
  2. Traceability Management
    MES creates real-time product traceability, tracking, search and traceability records. This helps administrators understand the status of WIP and finished products, ensure product quality during production, and facilitate product recalls if any.
  3. Real-time tracking and reporting
    The data about products, workers or machines will be collected by the MES system, stored data and given real-time reports. This helps businesses update error detection in the production process immediately. At the same time, MES also integrates quick technical solutions, minimizing defects in goods, ensuring better product quality.

Production Process Management

Resource management

The MES system supports the registration, management and analysis of factory resources, ensures the availability and capacity of the resources, and minimizes production interruptions or product errors due to the weak capacity of the resources. force.

Production planning supervision

MES collects information from orders, requirements from ERP systems or other enterprise planning systems, thereby making optimal use of available resources. At the same time, MES also monitors the production process, completed orders of shipments, ensuring on-time production and delivery.
Production performance analysis

From updating the raw data from the factory, the analytical MES system provides useful information about the production status such as Inventory (WIP), Overall Equipment Efficiency (OEE), production efficiency, etc. export,…

Statistical Process Control

Most of the MES systems are equipped with statistical functions such as online histogram, Xbar-R, Xbar-S, P, Pn,… and limit calculations, thereby detecting the missing points. reasonable in the production process and provide solutions.

Integrate, digitize processes
Information digitization
The information is digitized from the notepad into the web/tablet system and pushed the information from the SCADA system into a common data source. Improved problem solving of the environment
