Overall Equipment Effectiveness Calculator

Formula

The formula to calculate the Overall Equipment Effectiveness (OEE) is:

\[ OEE = \frac{IDCT \times GC}{PPT} \]

Where:

OEE – The overall equipment effectiveness.
IDCT – The ideal cycle time in minutes or hours.
GC – The good count or number of produced pieces that satisfy set requirements.
PPT – The planned production time in minutes or hours.

Definition

Overall Equipment Effectiveness (OEE): A metric used in manufacturing to analyze the theoretical total output of a piece of equipment.
Ideal Cycle Time (IDCT): The time it takes to produce one unit under ideal conditions.
Good Count (GC): The number of produced pieces that meet quality standards.
Planned Production Time (PPT): The total time planned for production.

Example

Let's say the ideal cycle time (IDCT) is 2 minutes, the good count (GC) is 500 pieces, and the planned production time (PPT) is 1000 minutes. Using the formula:

\[ OEE = \frac{2 \times 500}{1000} = 1 \]

So, the overall equipment effectiveness is 1.
