Overall Equipment Efficiency. The overall performance of a single piece of equipment, or even an entire factory, governed by the cumulative impact of 3 factors: Availability, Performance Rate (which includes machine speed), and Quality Rate. (Ex: 50% Availability (0.5) x 70% Performance Rate (0.7) x 20% Quality Rate (0.8) = 30%OEE) Use to measure how effective in relationship to the planned production schedule.
