Classification and application of enterprise MES Manufacturing Execution System

MES The system is an information processing management system for the workshop production execution layer of manufacturing enterprises . Enterprises MES Manufacturing execution system is composed of workshop digital management subsystem and real-time control factory subsystem . It can provide database management for enterprises 、 Production management 、 Resource coordination management 、 Quality supervision and management 、 Human resource management 、 Equipment management 、 Tool allocation management 、 Purchase deployment management 、 Cost accounting management 、 project management 、 Underlying data analysis 、 Upper data analysis and other management modules , It aims to create a comprehensive coverage for enterprises , A highly reliable manufacturing control platform .

MES Classification of systems

MES Special system is applied in workshop maintenance 、 Production supervision 、 Areas such as workshop mobilization and process group management .MES The integrated system is applied to machinery 、 Chemical industry and other workshop assembly fields , Functionally, the upper transaction processing and the lower real-time control system have been integrated . comparison MES Dedicated system ,MES The integrated system of has independent logical database 、 System integration 、 Overall data model .

MES Application fields of

At home MES There are two ways : One is the process manufacturing industry aiming at energy saving and consumption reduction MES, One is to realize the design 、 manufacture 、 Manage the discrete manufacturing industry with integrated manufacturing as the goal MES. The process manufacturing industry has : energy 、 chemical 、 Cement, etc . Discrete manufacturing industries have : Mechanical manufacturing 、 Electrical manufacturing, etc . In terms of production type , It can be divided into single variety mass production and multi variety small batch production . It is applied to process production industry and discrete manufacturing industry MES The system information function modules are similar , But in the process 、 There are certain differences in production methods . Enterprises need to meet their actual needs , Choose the right one MES System construction plan .

MES System function module

MES The system passes the process of workshop production 、 Design features of the product , Automate the production control workshop 、 Promote and apply the informatization management mode . The functions are as follows :

Production coordination management module :MES The system automatically sorts by convection waterline operation , And coordinate among all processes . Resource allocation and status management module :MES System to device 、 Tools 、 Unified management of personnel and materials , Monitor the completion progress of each work in real time . Production process and plan management module :MES The system can send raw materials to a certain process by attaching production instructions to materials . Document management module :MES The system automatically collects and distributes information related to product process design .

Product tracking and list management module :MES The system records the information of each product by monitoring the transmission status of the workpiece in real time , And send the information to the customer . Product performance appraisal module :MES The system passes the previous data information recorded in the workshop manufacturing process 、 Target points set by the workshop 、 Customers' demand for goods is analyzed , Get the identification report , Take this as the basis for auxiliary workshop control improvement . Human resource management module :MES The system updates employees' real-time status information by minute 、 Working hours 、 Attendance rate, etc , And according to the qualifications of employees 、 Skill level , Business needs 、 Operation mode , Decide on the best allocation scheme . Equipment maintenance management module :MES The system is monitored , Make the workshop equipment operate normally .

Production process control module :MES The system produces orders according to products , Self adaptive management of workshop assembly line . Production quality control module :MES The system tracks the products produced by the order in real time 、 Ensure product quality . Workshop information collection module :MES The system automatically collects and enters the working status of workshop personnel 、 Equipment bottom operation records and product logistics information . Employee responsibility traceability module :MES The system is based on the information entered by the workshop operator , Assign the responsibility of management and control to people . Line warehouse management module : Material out of warehouse 、 The products are automatically stored in the line warehouse after processing , And put the warehouse resources in categories . Production query module : Enter the production order number , You can query the current offline quantity of the work order product 、 Completion rate . Alarm management module :MES The system sets alarm indicators for the workshop assembly line process , If the workshop production index is higher than the preset index in the production process , The system will send an alarm to the management .
