What is OEE
The Overall Equipment Effectiveness (OEE) is calculated from availability, performance and quality and represents the productivity of a system or process after deducting losses in a single key figure.
OEE calculation can not only base on machine data but also on operational data for manual and workforce intensive processes.
By looking at the individual parameters of the OEE calculation, hidden potential can be quickly identified and increase efficiency in production.
Availability
Actual operating time / Scheduled operating time
x 100 = availability in %
Scheduled operating time is the total time available to a system or process, taking planned downtimes (e.g. work breaks) into account.
The actual (productive) operating time results from the scheduled operating time minus the duration of all stops and downtimes.
Quality
Good quantity / Total quantity produced
x 100 = quality in %
The good quantity is the total quantity produced minus defective parts (scrap).
The quality factor is obtained by dividing the quantity of good parts produced by the total quantity of all parts produced.
OEE
OEE =
Availability x Performance x Quality
Performance
Total quantity produced / Max. possible quantity
x 100 = performance in %
If the total quantity produced is divided by the maximum possible quantity within the actual operating time, the performance factor is obtained.
It is important to take the actual operating time into account here so as not to overestimate the availability in the performance factor.
