Briefly describe the 11 core functional modules of MES system

Traditional manufacturing enterprises , The emphasis of informatization construction is generally placed on ERP Management system and field automation system . But just relying on ERP And field automation are often unable to cope with the contradiction between production and management ,ERP Mainly for upper level resource planning management , Be able to deal with what happened before , You can also predict and deal with upcoming events , But I can't cope with the events that are happening now , Traditional production site management is only regarded as black box operation . And manufacturing execution systems （mes） Emphasize the implementation of manufacturing plan , It builds a bridge between planning management and process control , It just fills the gap between the two .

As a link between the decision-making level and the basic control level of the enterprise ,MES Straighten out the information flow within the enterprise .MES It can schedule accurately 、 send out 、 track 、 Monitor workshop production information and process , At the same time, it can measure and report real-time performance , It is the basic technical means to realize the agility of workshop production .

MES share 11 The main function modules include ： Detailed scheduling of processes 、 Resource allocation and state management 、 Production unit allocation 、 Document management 、 Product tracking and product list management 、 Performance analysis 、 Labor resource management 、 Maintenance Management 、 Process management 、 Quality management 、 Data collection . The functions of each module are briefly described as follows ：

1、 Detailed scheduling of processes ： Optimize and sort the job plan by sorting and scheduling the limited resource capacity ;

2、 Resource allocation and state management ： Manage the resources needed for production , Coordinate workers 、 Production equipment 、 Optimize the allocation of tools and materials , And track its current working status and completion ;

3、 Production unit allocation ： The operation of sending materials or processing orders to a processing unit through production orders to start a process or step ;

4、 Document management ： Manage and distribute products 、 Process planning 、 Records and documents related to design or work order , And the preservation and maintenance of historical production data ;

5、 Product tracking and product list management ： The history of each product is obtained by monitoring the position and status information of the workpiece at any time , This record can be traced up to the material component , Or trace to the end product ;

6、 Performance analysis ： Provide the result report of the actual manufacturing process , And compare it with historical records and expected goals ;

7、 Labor resource management ： Provide employee status information data updated by minute （ Including working hours 、 Participation rate 、 Achievement confirmation, etc ） It is convenient to guide the work of personnel ;

8、 Maintenance Management ： Track the maintenance of equipment and tools , Guide maintenance work , Ensure the normal operation of machines and other assets and equipment to achieve the implementation objectives of the plant ;

9、 Process management ： Monitor the production process , Guide the work flow of the factory , Improve processing efficiency and quality ;

10、 Quality management ： Real time analysis of information collected from the manufacturing site , Track and analyze the quality of the processing process , Ensure product quality ;

11、 Data collection ： Collect and organize people , Machine and bottom control operation data and process material information , So as to obtain the forms required for internal production operations 、 Record or parameter data .

The manufacturing workshop of an enterprise , It is the intersection of logistics and information flow , It is the economic benefit center of the enterprise . With the improvement of market economy , The role of workshop in manufacturing enterprises has gradually changed from traditional enterprise cost center to profit center , It strengthens the role of the workshop , therefore , Manufacturing execution system located in the workshop with execution function MES It plays a very important role . It not only establishes a complete traceability system for the factory , And improve the management level , Enhance the core competitiveness of enterprises .
