Watch this short example and learn how to calculate Overall Equipment Effectiveness (OEE).
As we’ve learned here, OEE is a metric which integrates availability, performance and quality metrics.
Formulae needed for OEE calculation are:
OEE = Availability x Performance x Quality
Availability = Operating Time / Planned Production Time
Performance = (Total Pieces / Operating Time) / Ideal Run Rate
Quality = Good Pieces / Total Pieces
Don’t forget to check your measurement units!
