Product knowledge

During the process of digitalization and refined management transformation in the manufacturing industry, the improvement of production transparency and process control capabilities is the core prerequisite for optimizing production processes, ensuring product quality, and enhancing production efficiency. Under the traditional production management model, the transmission of information such as progress, equipment, quality, and materials during the production process is delayed and the data is scattered, making it difficult for the management level to grasp the actual production situation in real time. Process control mostly relies on manual experience, which is prone to problems such as process disconnection, quality risks, and low efficiency. MES (Manufacturing Execution System) serves as the core hub connecting the upper-level management system and the on-site execution in the workshop. Through functions such as data collection, real-time display, process standardization, and anomaly warning, it breaks through the information barriers in the entire production process, promoting the transformation of production management from “experience-driven” to “data-driven”, and effectively enhancing the level of production transparency and process control capabilities. This article, based on industrial production practice, explores the core paths, application scenarios, and implementation key points of the MES system in improving production transparency and process control capabilities, providing a reference for enterprises to optimize production management.
I. Core Connotations and Enhancing Significance of Production Transparency and Process Control
Production transparency and process control are the core components of manufacturing production management. They are interrelated and mutually reinforcing, and their improvement is of great significance for the enterprise’s production and operation.
(1) Core Meaning
Production transparency focuses on achieving the visualization, queryability, and traceability of all information throughout the production process, covering aspects such as production planning, process execution, equipment status, material flow, and quality inspection. This ensures that all personnel in each position can obtain the necessary information in real time, breaking down information silos. Process control refers to the dynamic monitoring, standardized guidance, and timely adjustment of the entire production process to ensure that production activities proceed strictly in accordance with plans and process requirements. It promptly identifies and resolves abnormal issues in the production process, guaranteeing that production is carried out in an orderly, efficient, and high-quality manner.
(2) Enhancing Significance
Reduce information barriers and enhance management efficiency: The transparency of production can eliminate the information asymmetry among different positions and links, reduce communication costs, enable the management to quickly grasp the production situation and make scientific decisions; Process control can standardize the production process, reduce manual intervention and operational deviations, and improve the production execution efficiency.

2. Reduce quality risks and ensure product consistency: Through process control, real-time monitoring of production process parameters and inspection data is conducted to promptly identify quality abnormalities and prevent the expansion of quality issues; at the same time, a transparent traceability system can quickly locate the source of quality problems, providing a basis for rectification and optimization, and ensuring product quality consistency.
3. Optimize resource allocation and reduce production waste: The transparency of production can clearly show the usage status of equipment, manpower, materials, etc., facilitating the management team to coordinate and allocate resources, avoiding idle and insufficient resources; Process control can standardize material circulation and process connection, reducing waiting waste and rework waste, and lowering operational costs.
4. Support digital transformation and enhance management level: The improvement of production transparency and process control is the foundation of enterprise digital transformation. It can drive the transformation of production management from a loose style to a refined and data-based one, providing support for the subsequent promotion of intelligent scheduling and continuous improvement of the enterprise.
   II. The core path for enhancing production transparency through the MES system
   The MES system, through its four core functions of data collection, centralized display, information sharing, and traceability management, breaks down the barriers of production information and realizes the transparency of the entire production process, making the production process “visible, accessible, and traceable”.
   (1) Complete data collection throughout the process, laying a solid foundation for transparency
   Data is the core support for production transparency. The MES system collects production process data in multiple ways and from all dimensions to ensure the real-time, completeness and accuracy of the data: Firstly, it connects with workshop equipment, sensors, barcode scanners and other terminals to automatically collect data such as equipment operation status, process parameters and production volume, reducing manual intervention; Secondly, it standardizes the manual auxiliary collection process and realizes standardized entry of data that cannot be automatically collected, such as inspection results and abnormal situations, through workstation terminals; Thirdly, it covers six dimensions of people, machines, materials, methods, environment and measurement, sorts out key collection nodes, ensuring that all data in the production process is not missing, and providing a data foundation for transparent display and traceability.
   (2) Hierarchical visualization display to achieve precise information transmission
   The MES system presents the interface in a hierarchical manner, providing precise information services for different positions, enabling real-time visibility of production information: Firstly, the management cockpit displays the overall production plan, progress achievement rate, equipment utilization rate, and quality trend of the workshop, facilitating the management to grasp the production situation at a macro level; Secondly, the workshop-level board shows the production progress, work order status, and abnormal situations of each production line and process in the workshop, facilitating the scheduling and coordination of workshop managers; Thirdly, the workstation-level terminal displays the personalized information such as work orders, process parameters, and operation specifications required by the operators, ensuring that front-line personnel clearly understand the work requirements. Through hierarchical presentation, different position personnel can quickly obtain the required information, achieving transparency in the production process.
   (3) Full information sharing across all stages, breaking down information silos
   The MES system achieves information sharing throughout the entire production process by interacting with systems such as ERP, WMS, and SCADA, thereby breaking down information barriers. Firstly, it links with the ERP system to synchronize production plans, order information, material requirements, etc., ensuring that the production plan is consistent with the requirements of the upper management. Secondly, it links with the WMS system to synchronously update information such as material inventory and delivery progress, ensuring that materials are precisely matched with the production schedule. Thirdly, it links with the SCADA system to share equipment operation data, achieving transparency in equipment status. Fourthly, it realizes the synchronization of information among all processes and positions within the workshop, ensuring smooth process connection and avoiding production stagnation caused by information lag.
   (4) Full-process traceability management, enabling information to be traceable and retrievable
   The MES system achieves the query and traceability of all production process information through the establishment of a complete traceability system. Firstly, it conducts forward traceability, starting from the input of raw materials, tracing which products the raw materials of this batch were used for, which processes they went through, which personnel operated them, and which equipment was used until the finished products were manufactured. Secondly, it performs reverse traceability, starting from the product number or batch number, tracing the entire process information such as the raw material batch, processing procedures, process parameters, and inspection records. Through traceability management, not only is the production process made transparent, but also in case of quality issues, the source can be quickly located, providing a basis for rectification.
   III. The core path for strengthening production process control through the MES system
   The MES system achieves this through four core approaches: process standardization, dynamic monitoring, abnormal warning, and closed-loop management. These measures enhance the overall control of the production process, ensuring that production activities proceed smoothly and quality remains under control.
   (1) Standardize the production process and regulate the production execution
   The MES system integrates standardized production processes and operation norms into the system, eliminating the randomness of manual operations and standardizing production execution. Firstly, it clearly defines the standard process routes, process nodes, and operation requirements for each product, ensuring that the production process proceeds strictly in accordance with the process specifications. Secondly, it solidifies the workflow of task assignment, process flow, and work reporting, clearly defining the operation standards and time requirements for each link, avoiding process disconnection. Thirdly, it restricts non-compliant operations. For operations that do not follow the norms, the system promptly alerts and prohibits them, ensuring the standardization and consistency of the production process.
   (2) Conduct dynamic monitoring of the production process and obtain real-time information on the production status.
   The MES system conducts dynamic monitoring of the entire production process, tracking the production progress, equipment status, quality conditions, etc. in real time, ensuring that the management can promptly grasp the production situation. Firstly, it monitors the production progress, comparing the production plan with the actual execution, and presenting real-time progress deviations to facilitate timely adjustment of production scheduling. Secondly, it monitors the equipment status, tracking the operating status, startup rate, and downtime of the equipment, promptly detecting equipment abnormalities to prevent production interruptions caused by equipment failures. Thirdly, it monitors the quality situation, collecting inspection data in real time, tracking changes in quality indicators, promptly identifying quality risks, and ensuring controllable product quality.
   (3) Real-time anomaly warning and rapid response and handling
   The MES system achieves real-time warning for various abnormalities during the production process by setting abnormal warning thresholds. This promotes the rapid handling of abnormalities: Firstly, for common abnormalities such as equipment failures, quality overruns, material shortages, and deviations in process parameters, clear warning thresholds are set; Secondly, when an abnormality occurs, the system uses methods like LED displays and message notifications to promptly alert the relevant responsible personnel, clearly indicating the type of abnormality, location, and impact range; Thirdly, an abnormality handling process is established, specifying the handling time limit and responsibility division to ensure that abnormalities can be responded to quickly and resolved promptly, avoiding the expansion of the problem.
   (4) Establish a closed-loop management system to promote continuous improvement
   The MES system establishes a closed-loop management mechanism of “monitoring – warning – handling – feedback – optimization” to promote continuous improvement in the production process: Firstly, it records abnormal situations during the production process, the handling process and results, forming a complete abnormal handling archive; Secondly, it conducts statistical analysis of abnormal data, identifies frequent abnormal types and causes, and formulates targeted improvement measures; Thirdly, it incorporates the improvement measures into the system to optimize the production process and operation norms, avoiding the recurrence of similar abnormalities; Fourthly, it tracks the implementation effect of the improvement measures, continuously optimizes and adjusts, and continuously enhances the process control level.
