OEE (Overall Equipment Effectiveness) is the most familiar method of checking and improving the effectiveness of a press. It identifies the percentage of manufacturing time that is truly productive. An OEE score of 100% means you are manufacturing only good sheets, at maximum speed, and without downtime. In OEE terms, this means 100% Quality (only good sheets), 100% Speed (maximum speed), and 100% Time (no downtime).
There are 3 measures that determine OEE%.
OEE % = Speed Index (%) * Quality Index (%) * Time Index (%) |

Speed Index determines how your machine performs when producing. The higher the average printing speed, the more productive you will be with your press.
Speed Index % = ([Gross Volume] / [Production Time (h)])/ Max. Speed (1/h)] |

Max. Speed is given for the device based on the Prinect device configuration parameter.
Quality Index determines the relation between good sheets and waste sheets. The higher the Quality Index, the less waste sheets you will have produced.
Quality Index % = [Net Volume] / [Gross Volume] |

Time Index calculates the amount of time your machines are active. The higher the Time Index, the more productive you will be with your press.
Time Index % = [Production Time (h)] / [Operating Time (h)] |
