OEE

OEE = Availbility * Performance Rate * Quality rate

where

Availbilty =(Calender Hours – Planned losses -Unplanned lossed)/ Calender hours

Performance rate = Operatig Efficiency * Rate Efficiency

where ,
Operating Efficiency=(Available hours -Losses beyond equipment/plant’s
control
——————————————————
Available hours
Rate Efficiency = Actual output/design output

Quality Rate = OK product tonnage/Total input material
