Overall Equipment Effectiveness |
Performance Rate = processed quantity x actual cycle time -------------------------------------- operation time |
Actual cycle time is the agreed floor to floor time for the component and operation being measured.
To determine the O.E.E. of the equipment;
Availability x Performance Rate X Quality Rate
Be prepared for a figure that is lower than you might think. On initial investigation the average company will record figures of 50 - 60 % Experience shows that the ideal conditions are:
Therefore the ideal overall equipment effectiveness should be :
0.90 x 0.95 x 0.99 = 85+%
This figure is not a remote goal, many companies are achieving in excess of this.
