AMR's definition of MES
AMR, an American advanced manufacturing research institute, defines MES as "a workshop-oriented management information system located between the upper planning management system and the lower industrial control", which provides operators and managers with the execution and tracking of plans and the current status of all resources (people, equipment, materials, customer needs, etc.). ).
AMR puts forward a three-tier business model of enterprise information integration, including decision-making layer, execution layer and control layer. The first decision-making layer (ERP) mainly provides comprehensive management decisions for enterprises; The second executive layer (MES) is mainly responsible for the coordination, tracking, discovery and monitoring of related trends at the workshop level; The third control layer (SFC) is directly responsible for the production control of the factory.

MESA's definition of MES
MESA, a manufacturing execution system association, defines MES as:
Message (short for message)
Through information transmission, the whole production process from order to product completion can be optimized and managed. When real-time events occur in the factory, MES can react and report in time and make use of the current accurate data.
Guide and deal with them. This rapid response to state changes enables MES to reduce internal activities with no added value and effectively guide the production and operation process of the factory, which not only improves the timeliness of delivery of the factory.
Ability, improve the circulation performance of materials, but also improve the rate of return on production. MES also provides key task information about product behavior within the enterprise and the whole product supply chain through two-way direct communication.
MESA's definition of MES emphasizes the following three points:
(1)MES is to optimize the whole workshop manufacturing process, not to solve a production bottleneck.
(2)MES must provide the function of real-time collection of production process data and make corresponding analysis and processing.
(3)MES needs to interact with planning layer and control layer to realize enterprise information integration through continuous information flow.

Starting from 1997, the National Organization for Standardization (ISA) began to compile "ISA-95 enterprise control system integration standard", aiming at establishing ISA-95 enterprise information system integration standard.
At present, the contents of standard documents include the following four parts: the first part: models and terms, and the second part: Data structure and attributes (data
Structure and attributes), Part III: Manufacturing model.
Part IV: Technical report of transaction.
Issa-
Standard 95 defines the terms and standards used in the integration of enterprise-level planning management system and factory-level control system, and its contents mainly include informationization and standardization. Among the information involved in ISA-95
It includes product definition information, production capacity information, production progress information and production performance information. ISA-95, in addition to the above information, is an important part of the standardization of production object model. Issa-
The production object model of 95 is divided into four categories and nine models according to their functions. These four categories are resources, capabilities, product definitions and production plans. These nine models are: resources include people, equipment, materials and process segment objects; competence
Including production capacity and process section capacity; Product definition includes product definition information; Production planning includes production planning and production performance. These nine models constitute the basic model framework of ISA-95.

Bandex's understanding of MES
Message (short for message)
What is the essence of? MES is an integrated system for comprehensive management of production site. MES replaces the original workshop requirements such as equipment management, quality management, production scheduling, DNC, data acquisition software and so on with the idea of integration.
Use an independent software system. MES plays a connecting role in information system, and it is an information hub, emphasizing the real-time nature of information. MES starts with the execution of production plan, the traceability of production process and the normal operation of equipment.
Efficient utilization, product quality assurance, worker scheduling and reasonable incentives are integrated to manage the production site. Enterprises in different industries and different production modes have applied some modules in MES, or are in.
It is extended and applied on the basis of MES.
