Overall Equipment Effectiveness

Overall Equipment Effectiveness (OEE) is a comprehensive metric used in manufacturing to assess the efficiency and effectiveness of equipment. It identifies areas for improvement by measuring the percentage of manufacturing time that is truly productive.

#Formula

$$\text{OEE} = \text{Uptime} \times \text{Cycle Time Performance} \times \text{Yield}$$

where

$$\text{Cycle Time Performance} = \frac{\text{Cycle Time}}{\text{Actual Cycle Time}}$$

So the full Threaded OEE calculation is:

$$\text{OEE} = \text{Uptime} \times \text{Yield} \times \frac{\text{Cycle Time}}{\text{Actual Cycle Time}}$$

#Example

Metric	Value
Uptime	95%
Yield	99%
Cycle Time	30 seconds
Actual Cycle Time	32 seconds

$$OEE = 0.95 \times 0.99 \times \frac{30}{32} = 0.88 \text{ or } 88\%$$
