+### 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 |
