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.

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:

1 2 ... 86 87 88 89 90 91 92 93 94 95 96 ... 124 125
