What is the role of MES system in workshop production management?

1. What is MES system?

Manufacturing execution system is manufacturing execution system;

MES system definition

MES is to manage the company's overall resources according to the company's business objectives, providing the company with the execution means to achieve the implementation objectives, connecting the theoretical data of the basic information system with the actual data of the factory through the real-time database, and providing the communication function between the business planning system and the manufacturing control system.

Second, the core functions of MES system

2. 1 production scheduling management: MES system optimizes workshop performance through job sequencing and scheduling under the condition of limited resource capacity; Achieve rapid scheduling and respond quickly to changes in demand. Synchronize, real-time and bind to all resources, whether it is materials, mechanical equipment, personnel, supply, customer demand, transportation and other factors that affect the plan;

2.2 Resource allocation and status management: MES system guides the coordinated production of personnel, machinery, equipment, tools and materials, and tracks their current working status and just completed situation;

2.3 production process planning management: MES system sends materials or processing instructions to a processing unit through production instructions to start the operation of processes or steps;

2.4 document control management: MES system manages and distributes information related to products, process regulations, designs or work orders, and collects standard information related to work and environment;

2.5 product tracking: MES system obtains the historical record of each product by monitoring the position and state of the workpiece at any time, and provides users with the traceability of the product group and the use of each final product;

2.6 product performance analysis: MES system compares the measured results of the actual manufacturing process with the past historical records, the goals set by enterprises and the requirements of customers, and uses its output report or online display to assist the improvement and improvement of performance;

2.7 Human resource management: MES system provides employee status information data (working hours, attendance, etc. ) update every minute, and guide the work according to the changes of personnel qualifications, working methods and business needs;

2.8 Equipment maintenance and management: MES system ensures the normal operation of assets and equipment such as machines and realizes the implementation goal of the factory through activity monitoring and guidance;

2.9 production process management: MES system guides the work flow of the factory according to the planned and actual product manufacturing activities (this function can actually be realized through production unit allocation and quality management);

2.2. 1 production quality management: MES system records, tracks and analyzes the quality of products and processing in real time according to the engineering objectives, so as to ensure the quality control of products and determine the problems needing attention in production;

2.2.2 On-site data collection: MES system monitors, collects and organizes the operation data, process and material information from personnel, machines and bottom control, which can be manually entered in the workshop or obtained by various automatic means;
