Production Overall Equipment Effectiveness (OEE) Trend Report

Overall Equipment Effectiveness (OEE) is a measurement frequently used by countless manufacturing and production entities across a wide range of industries. OEE identifies the amount of manufacturing time that is truly productive. This metric is used to identify losses, benchmark progress, and improve the productivity of manufacturing equipment. 

So, the Production OEE Trend Report does just that. This report plots a graph illustrating how your Production OEE is trending over a specified range of time. 

For example, an OEE score of 100% would mean only good parts are being manufactured, as quickly as possible, with absolutely zero downtime. 

• 100% Quality (zero defects) 
• 100% Performance 
• 100% Availability of all equipment 

If that seems like a lofty goal, that's because it is. And pretty unrealistic, too. With that in mind, let's look at how OEE is calculated. 

OEE = OA% * Quality% * Performance per Part%

Pro-Tip: If your OEE Pareto Report results do not match exactly your OEE Trend Report results 

The OEE Pareto Report uses the precision value from the OEE metric for all of the values displayed. Some customers have this metric set to ' .1 '.

The OEE Trend Report uses the precision value for each metric individually and as specified by the customer in the Production Settings. The default value for precision is whole numbers only, which is what the OA calculation uses. That is why there is sometimes a difference in the reported results.
