If Ideal Cycle Time for a given machine is 60 seconds and the Operating Time is 1 hour then at 100%
performance we would have to process the following number of items:
Performance = Ideal Cycle Time / (Operating Time / Total Pieces)
1 = 1 / ( 60 / Total Pieces)
Total Pieces = 60
If we had processed 48 items the performance would be:
Performance = Ideal Cycle Time / (Operating Time / Total Pieces)
= 1 / ( 60 / 48 )
= 0.8 (80%)
For a factory line, it is the same calculation as above for all process points in the factory line. The
lowest process point availability is returned.
OEE Quality (Overall Equipment Effectiveness) Gauge and Indicator
Filters Supported – Factory Line/Process Point
Looks at first pass yield achieved during planned production time during a specified time window.
Quality = (Total Pieces – Total Failed) / Total Pieces
Example
Unit 1: passed
Unit 2: failed then passed
Unit 3: failed twice
Quality
= (Total Pieces – Total Failed) / Total Pieces
= (3 – 2 ) / 3
= 0.33 (33.33%
For a factory line, it is the same calculation as above for all process points in the factory line. The
lowest process point availability is returned.
OEE (Overall Equipment Effectiveness) Gauge and Indicator
Filters Supported –Factory Line/Process Point
The product of OEE Availability, OEE Performance and OEE Quality.
Example
OEE = Availability x Performance x Quality
= 0.75 x 0.73 x 0.33
= 0.18
= 18%
OEE Overview
OEE = Availability x Performance x Quality
Where
Availability = Operating Time / Planned Production Time
Performance = Ideal Cycle Time / (Operating Time / Total Pieces)
Quality
= Good Pieces / Total Pieces
The order of calculation is as follows:
