Why does the factory need a MES system even though it already has an ERP system?


In modern manufacturing, the competitive advantage of enterprises comes from automation through the application of advanced technology solutions such as MES, ERP. However, deploying a modern software, especially when it allows your business to manage all resources like ERP, factories will face questions about: Is it really necessary to integrate MES system integration when the enterprise already has ERP?

The following article Retex will help you solve this one concern

Distinguish between MES and ERP systems

In order to keep up with the digital era 4.0, many manufacturing enterprises have invested huge sums of money for an ERP enterprise resource planning software. The main reason given is the popularity of the ERP system with its ability to integrate management of all aspects of business & manufacturing operations, including planning, product development, manufacturing processes. , finance, sales and marketing.

However, it should be remembered that ERP only plays the role of a means of information sharing throughout the organization, but cannot control and accurately operate the production process.

The biggest reason is because ERP is located on the 4th floor in the CIM integrated production system tower – the planning layer, while there is no MES production management system – the 3rd floor.


According to the CIM tower, no MES means the lack of an intermediate connection layer between the ERP and the lower production execution layers (layers 1, 2). At that time, the exchange of information between ERP and production implementation will be through manual operations such as notes, tables, excel, forms.

Although ERP plans resources automatically and intelligently, data input to the ERP system is subject to errors. This leads to inefficient ERP operation and failure to meet the requirements of the organization when investing. In manufacturing, ERP solutions are often used in conjunction with other specialized software systems, especially MES systems.

The MES is responsible for collecting production data information to transfer back to the 4th floor. To do this, the MES implements precise control and operation of the production process. MES supports comprehensive tracking of all aspects of production activities (inventories, raw materials, machinery maintenance, …), helping businesses update production activities immediately, promoting product inspection. products, optimizing resources and managing production processes in real time.

Why integrate MES and ERP?

It can be seen that although the two systems ERP and MES have some similarities, the data properties and administrative goals are different, which does not cause overlap when applied. The implementation of two systems helps the factory to manage details in each department, inter-departmental processes. Moreover, enterprises have a deeper view and overview of their entire production activities.

ERP knows “why”, while MES knows “how”

ERP mainly supports strategic decisions, while MES supports the precise and complete execution of the manufacturing process. As a result, these two systems are integrated allowing the manufacturing facility to seamlessly respond to the needs of individual customers, managers, suppliers, and even internal employees.

Real time – the key to the production process

At the ERP level, a single managed strategic change can generate about 10 times more change volume than at the production level. Therefore, the MES system has to be specifically engineered and laid out to allow both quality and changeover time to happen quickly and accurately in real time.

Have a key competitive advantage when it comes to supply chain efficiency

Information integration can only be done through the association of all levels, from the production layer upwards. Only with the timely, accurate, continuous and efficient exchange of information achieved by the MES system can the supply chain function effectively.

An example from the textile industry: Suppose a component installed in a textile factory does not deliver the agreed performance. All other departments are forced to prove that the problem is not on their side. If they cannot prove this, they will be asked for emergency damages.

ERP/MES integration is an important step towards Industry 4.0

For modern manufacturing enterprises with international and regional goals, the integration of two ERP and MES systems is absolutely necessary. Accordingly, ERP and MES will allow your business to take advantage of the core competencies of technology to optimize production and business activities to meet business requirements on Q – C – D (Quality – Quality). quantity, Cost – Cost, Delivery – Progress).

As can be seen, if your business has not implemented ERP and MES integration, you should consider implementing this plan as soon as possible. Because as analyzed, the implementation of modern technology solutions in production creates the basis for your company to succeed in the 4.0 digital age.
