OEE Standard Formulas¶

OEE formula

Availability related formula

The sum of downtimes is determined through different machine states and the underlying time model.

Performance related formulas

Theoretical Output depends on the currently produced products in the selected timeframe. If different products are produced in the selected timeframe, then the Theoretical Output is the sum of the different timeframes for which the product has been produced multiplied by the product individual design speed.

The number of total parts must be collected.

Quality related formulas

As shown in the formula above, two out of the three parameters (Total Parts, Good Parts, Rejected Parts) must always be collected. The third variable can always be calculated based on the other two variables.
