A table to understand the difference and connection between MES and ERP

Introduction to MES

MES stands for Manufacturing Execution System (MES) was proposed by American AMR company (Advanced Manufacturing Research, Inc.) in the early 1990s. It aims to strengthen the execution function of the MRP plan and control the MRP plan with the shop floor. Connected through the execution system. The on-site control here includes PLC program controller, data collector, bar code, various measuring and testing instruments, manipulator, etc. The MES system has set up the necessary interfaces to establish cooperative relations with manufacturers that provide production site control facilities.



Introduction to ERP

ERP system is the abbreviation of Enterprise Resource Planning. It refers to the information technology and advanced management ideas, which is built on the basis of information technology, and provides decision-making means for enterprise employees and decision-makers with systematic management ideas. Management platform. It is a new generation of integrated management information system developed from MRP (Material Requirements Planning). It expands the functions of MRP, and its core idea is supply chain management. It jumped out of the boundaries of traditional enterprises, optimized the resources of enterprises from the scope of the supply chain, optimized the operation mode of modern enterprises, and reflected the market's requirements for enterprises to allocate resources rationally. It plays a significant role in improving business processes and core competitiveness of enterprises.

question answer

1

MES manufacturing execution system

Is it necessary to use this system?

(What's the use of this system?)

The MES system can timely and maximize the strict management of quality through the real-time collection of on-site product information; on the other hand, the MES system can be used to achieve strict management of production plans, thereby maximizing the timeliness of products deliver. Provide assurance in both quality control and production schedule. So it is necessary to go to this system.

MES manufacturing execution system

How to use this system?

Management of production factors through modules such as plan management, workshop management, and semi-finished product management, quality management through on-site collection of product information and process quality management modules, and parts distribution management through logistics management modules.

What is the relationship between this MES system and CAD?

CAD design drawings to provide data support for MES

4

What is the relationship between the MES system and PDM? What is PDM?

PDM provides technical details of all parts and components and provides data support for MES.

5

MES manufacturing execution system

What is the relationship between the MES system and CAPP? What is CAPP?

CAPP provides procedures, working hours, quotas, etc. for self-made parts to provide data support for MES. CAPP's English name is Computer Aided Process Planning, and Chinese translation is computer-aided process design. CAPP is a method that adds relevant process information to the product design data of an enterprise, such as adding processes, working hours quota, etc., to convert it into product manufacturing data. This technology helps process designers complete the design from rough to finished products.

What is the relationship between the MES system and ERP? What is ERP?

(Where is it more advanced than ERP or where is the advantage of MES?)

ERP is from the perspective of the whole company, and manages the company's technology, procurement, inventory, production and other information. It manages a lot, but it is not detailed and specific. MES is specifically for on-site management of the workshop, such as: to which process and how much of the production of each component has been completed; whether the lathes and other equipment on the workshop site are operating in good condition, whether there are any failures, a few are broken, and where are they broken, When to fix it; In addition, the quality of parts and components on-site inspection, how many have passed, how many failed, and where failed, etc. These information, more targeted.

7

MES manufacturing execution system

Is it necessary to go to MES after going to ERP?

Enterprises often face a short period of time from product design to completion of production, resulting in an incomplete or even lacking BOM, and ERP cannot be used without a BOM. MES can achieve normal management of production plans without a BOM.

What is the relationship between the MES system and BOM? What is BOM?

BOM is the abbreviation of material details, provides data support for MES, and is the source of data in MES system.

9

Without BOM, how does MES obtain data information, etc.?

Obtain data by maintaining the product knowledge base and on-site data collection in the MES.

10

MES manufacturing execution system

How to collect product information on site?

Collect barcodes on products by collecting barcode guns to obtain information such as product order number, plan number, batch number, part number (drawing number), process serial number, etc.

11

MES manufacturing execution system

How to control the quality?

Through the acquisition of this information to control the quality.

12

What effect will be achieved after using MES?

Through the MES system, the order and refinement of management can be realized, the level of enterprise management can be improved, and the production efficiency can be greatly improved.

13

MES manufacturing execution system

How to integrate with the company's existing system?

Through the integration of the background database and other methods to achieve integration with other systems to achieve data sharing

14

MES manufacturing execution system

How to keep confidential?

The company will build a special security network for confidentiality, and the computers and related data related to the MES system will be run on this security network to ensure that the relevant security requirements are met.

What is the relationship between MES and this XXX project? What role can it play in this project?

At present, quality inspection and plan delivery are all manual, with low efficiency and low accuracy. Using this MES can greatly improve work efficiency and accuracy of quality inspection, and can effectively guarantee the production progress and accuracy of the project.
