### 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 |
