OEE = OVERALL EQUIPMENT EFFECTIVENESS

OEE - Overall Equipment Effectiveness.

This term is used to check the EFFECTIVENESS of a machine.
Its a production indicator which shows how effectively a machine is operating / working against planned output.

This is a best practice developed by -
"Seiichi Nakajima".

OEE is calculated with considering Availability, performance and Quality.

How to calculate OEE :

Consider  Following Terms :

1. Schedule time. =
2. Planned Downtime=
3. Net Available Time: NAT=
          (Schedule Time - planned downtime)
4. Unplanned Downtime =
5. Net Operating time: NOT =
           (NAT - unplanned downtime)

6. Cycle time.                =
7. Part Produced.         =
8. Part Scrapped.         =

9.   Ideal Operating Time: IOT =
        (Cycle time x Part Produced) /60 (if sec)

10. Lost Operating Time : LOT =

Calculations:
1. Availability=  NOT / NAT
2. Performance= IOT / NOT
3. Quality.         = (IOT - LOT) / IOT
4. Time to produce good parts = IOT-LOT
5. OEE.  =
    (Time to produce good parts / NAT)*100
