Manufacturing Execution System
Manufacturing execution system (MES) allows comprehensive management from production planning to storage and release of inventory.
It helps to clarify collection and payments of raw and subsidiary materials and handles work order, manufacturing process, and work production record by units in the production planning stage.
It also helps to manage production history and serial number. Moreover, barcodes allow real-time collection and analysis of on-site data by using a wired/wireless scanner or PDA when managing storage and release, which reduces time spent in decision making.
Configuration of MES System

- Operation status by facility
- Non-operation report by facility
- Ranking facility breakdown
- Ranking facility non-operation
Release Management

- Cell Monitoring
- Inventory status by product
- Inventory status by location
- Long-term inventory status
- Monitoring semi-finished products warehouse
- Monitoring finished products warehouse
- Inventory Discrepancy
Occurs due to dependence on manual inventory management
Leads to delays in record and errors (24 hours)
- After Improvement
Introduces a barcoding system to standardize all documents
Establishes real-time warehouse management based on physical inventory and computerization
- Difficulty in Tracking Production Progress by Production Stage
Causes delays in registration due to manual documentation of performance leads to errors caused by a human error by a worker
Unable to identify inventory amount between stages and inventory loss during transfer After Improvement
- After Improvement
Collects real-time production performance data by transfer unit
Manages storage and release in real-time for clear tracking of inventory by line and supply
(input, performance, defect rate, unadjusted ratio)
- Difficulty in Clear Identification of & Immediate Response to the Site
Decreases facility operation rate by failing to understand operation status
and non-operational causes of facility
Difficult to analyze causes when having clients’ complaints and prevents reoccurence of errors and defects due to the lack of systematized quality management
- After Improvement
Improves operation rate and analyzes and promptly responds to non-operation factors by analyzing the current operation rate of facilities
Improves product quality qualifying for ISO-9001 standard by using statistics-based management method in understanding factors in decreasing quality
Leads to easier process when certified as meeting ISO-9001 standards and under external audit
- Demand in ERP Infrastructure
Leads to repetitive or missing tasks in procurement
Possibility to cause issues in production plan without considering data from production site
- After Improvement
Provides accurate production planning and procurement management by real-time reflection of the site data on ERP
Onsite data upload, analysis, and support
