MES (Manufacturing Execution System)

Manufacturing Process, From Raw Material to Finished Product

A Manufacturing Execution System (MES) is a comprehensive, dynamic software system that monitors, tracks, documents, and controls the process of turning raw materials into finished products. Sitting as a functional layer between ERP (Enterprise Resource Planning) and process control systems, MES gives decision-makers the data they need to improve shop-floor efficiency and optimize productivity.

MES Features

Resource Allocation Status
Manages resource data such as equipment, tools, materials, specifications, and documents, providing detailed availability information to enable accurate production planning and execution.
Operation/Detail Scheduling
Maximizes utilization of equipment resources and manages detailed work schedules by adjusting sequence, priority, and characteristics. Uses resource planning data to build the best combination of tasks and set their order to minimize downtime.
Dispatching Production Units
Manages production sequence through work objects such as jobs, batches, and work orders, and allows the work order to be changed in real time based on shop-floor conditions.
Document Control
Controls and manages the documents needed on the shop floor, including work orders, drawings, standard operating procedures, recipes, specifications, and various forms.
Data Collection/Acquisition
Collects, stores, and manages process, material, work, operation, and log information in real time. Supports both manual worker input and automatic data acquisition from equipment.
Labor Management
Tracks worker status history down to the minute, providing data such as clock-in/out, work assignment, and attendance.
Quality Management
Performs real-time equipment defect data collection, statistical process control (SPC), and statistical quality control (SQC), providing data for defect prevention and root-cause analysis to support reliable quality management.
Process Control
Monitors and controls the entire manufacturing production process. Supports automated system control or allows work instructions to be issued in line with company rules and policies.
Maintenance Management
Manages the equipment, tools, and other resources needed for planned and emergency maintenance, supporting efficient management of equipment history and maintenance schedules (overhauls).
Product Tracking and Genealogy
Provides visibility into production history and real-time tracking of products, allowing you to manage and look up the history of work orders, raw materials, lots, tools, equipment, processes, equipment status, and production targets.
Performance Analysis
Combines production performance data with shop-floor output information to support various reports and productivity metrics, letting you check work performance in real time or as a summary.

A Core Technology and Essential Tool in Manufacturing

As manufacturing environments rapidly become smarter, many manufacturers are turning their attention to integrated production management systems like MES. Digitizing material flow and equipment operation data on the shop floor in real time makes it possible to precisely track progress against plan, cost, and quality variance.

Building on a data collection and storage infrastructure to integrate automation, raw material/process/equipment history, and cost/unit-price information is no longer optional for individual companies — it is becoming an essential requirement that determines manufacturing competitiveness.

MES instantly collects all information generated on the shop floor, organizes what's needed to raise production efficiency, and supports material management and real-time data sharing. By enabling accurate inventory management and history tracking, MES has established itself as a core technology and essential tool for manufacturing.

Key Strengths

Live Equipment Production Tracking (Raw Data) Management

Gathers equipment data in real time from MES, PLC, RS232, and other sources, enabling integrated management and sharing based on per-equipment operation status and signal data.

Barcode-Based Material & Production Management

Attaching barcodes to materials and stock minimizes manual data entry, so receiving, allocation, inventory, and performance information can be checked and looked up instantly.

LOT History & LOT Traceability Management

Assigning lots to production and managing lot history enables handling and traceability from raw material to finished product, and real-time monitoring lets you immediately check the status of relevant lots whenever an issue occurs.
