What is OEE and how is it calculated

Question

Accepted Answer

OEE stands for Overall Equipment Efficiency. It is a measure of how effectively a manufacturing process is utilized.

OEE is calculated by multiplying Availability, Performance, and Quality factors.
Availability measures the percentage of time the equipment is available for production.
Performance measures the speed at which the equipment operates compared to its designed speed.
Quality measures the percentage of good-quality products produced by the equipment.
OEE = Availability x Performance x Quality
For example, if the availability is 90%, performance is 95%, and quality is 98%, the OEE would be 0.90 x 0.95 x 0.98 = 0.8364 or 83.64%.
