Must know before deployment: the difference between discrete MES and process MES

The MES system plays an important role in the manufacturing industry, and is also a necessary condition for the transformation from the traditional manufacturing industry to the intelligent information manufacturing industry. In the current manufacturing industry, different enterprises have different needs, so the choice of MES systems is also different. MES systems are mainly divided into two types: discrete and process. What is the difference between the two? Enterprises must understand whether they are discrete or process-based before deploying to avoid making the wrong choice.

Discrete MES system
The discrete MES system is suitable for the production management of customized products. From the beginning of the production plan to the finished product, the entire process is controlled by the MES system.

Process MES system
The process-type MES system is suitable for production management and control in the chemical industry. Its main purpose is to make the most prone to product quality ingredients, feeding and emulsification processing processes controlled and reviewed, and to transfer product quality and cost control from the hands of front-line operations staff In the hands of R&D engineers.



Analysis of the difference between flow and discrete MES
Process MES is mainly used in process industries such as metallurgy, chemical industry, steel, etc.; Valley discrete MES is mainly used in discrete industries such as automobiles, electronics, construction machinery and so on. In addition, process MES and discrete MES also have significant differences in production methods, process management and control, production scheduling and task dispatching, resource allocation and status control, quality management, and maintenance management.

1. Differences in production methods: Process-based industries are mainly based on inventory, batch and continuous production methods; while discrete industries have both order-based production and inventory-based production; both batch production and single-piece small batch production Happening.

2. Process management differences: Process industries dynamically monitor discrete events in the process to automatically correct production operations or provide decision support; while discrete industries communicate with the bottom of data collection and quality control systems in real time.

3. Differences in production scheduling: Process-based industries need to be combined with resource allocation for on-site dynamic allocation; while in discrete industries, all tasks are handed over to your equipment during scheduling.

4. Differences in resource allocation: Process industries provide real-time status of various resources and are closely coordinated with task allocation; while discrete industries are subject to fluctuations in production and require real-time early warning of the production process.

5. Differences in quality management: Process industries track raw materials, parts and personnel; discrete industries feedback and track real-time or indirect inspection results.

6. Maintenance management differences: The process type needs to manage and guide the maintenance activities of equipment tools and molds, while the discrete industry is based on the collected data for fault analysis and diagnosis.



Therefore, it can be seen that the production planning of process manufacturing is relatively simple. It is often issued in the form of daily output, and the plan is relatively stable, the production equipment capacity is fixed, the production process is also fixed, and the work center arrangement is in line with the process route. The events passing through each work center are close to the same; materials are driven by machines from one work point to another, and individual products are in stock; the entire production process is mainly focused on the control of the quantity, quality and process parameters of the materials.

In the discrete manufacturing process, material changes rarely occur because the product is assembled from various materials, and there is a certain quantity ratio between the product and the required materials.

Whether it is discrete manufacturing or process manufacturing, in the current digital era, the transformation from traditional manufacturing to digital requires an MES system. In addition, Google now has a SaaS version and a localized MES system. The SaaS version of the cloud service is safe and stable. It can be used anytime and anywhere. It has low cost, does not require a developer, and the operation is very simple. The system is also free to upgrade for life. Whether it is a large-scale manufacturing or small and medium-sized, you can choose according to your actual needs.
