OEE is calculated using the formula: OEE = Availability × Performance × Quality Each component is calculated as follows:
Availability: Measures the percentage of scheduled time that the equipment is available to operate. It is calculated as uptime divided by scheduled production time. Performance: Measures the speed at which the equipment operates as a percentage of its designed speed. It is calculated as actual output divided by maximum possible output. Quality: Measures the percentage of good units produced compared to the total units produced. It is calculated as good units divided by total units.
