2.5 Equipment OEE Analysis
OEE Concept:
OEE (Overall Equipment Effectiveness) is a ratio measuring the actual production capacity versus the theoretical production capacity of equipment.
OEE Calculation Formula:
OEE = Availability × Performance × Quality
Where:
- Availability = Actual Operating Time / Planned Operating Time × 100%
- Performance = Actual Output / Theoretical Output × 100%
- Quality = Qualified Product Quantity / Total Output Quantity × 100%
OEE Standards:
| OEE Value | Level | Description |
|---|---|---|
| ≥85% | World Class | Excellent |
| 70%-85% | Good | Meeting standard |
| 60%-70% | Average | Needs improvement |
| <60% | Poor | Requires focused improvement |
OEE Analysis Dimensions:
| Analysis Dimension | Loss Type | Description |
|---|---|---|
| Availability | Fault Downtime | Downtime due to equipment failure |
| Availability | Changeover & Setup | Product changeover and setup time |
| Performance | Idle & Minor Stops | Short stops |
| Performance | Speed Loss | Running speed below theoretical speed |
| Quality | Scrap | Defective products |
| Quality | Rework | Products requiring rework |
OEE Improvement Measures:
| Loss Type | Improvement Measures |
|---|---|
| Fault Downtime | Strengthen preventive maintenance |
| Changeover & Setup | Optimize changeover process |
| Idle & Minor Stops | Optimize operation process |
| Speed Loss | Equipment upgrade and modification |
| Scrap & Rework | Strengthen quality control |
