Ideally OEE is used to highlight areas of improvement for individual equipment but many companies would like to compare their OEE across plants, even for equipment with different complexity, technology, utilisation etc.

One way to do this is to apply a weighting factor based on potential output within a set time period (rather than the actual production).  This can help to identify the equipment with the greatest potential impact on either achieving or not achieving the required production; the higher the weighting percentage the higher the impact.

Weighting factor = Line Potential Production / Plant Potential Production

Where:  Potential Production = Actual production / OEE

The calculation for the weighted OEE would then simply be: Actual plant production / Potential plant production
