After learning the theory of how to Calculate OEE, this article will show you a practical case that you can use as a reference for the calculation of OEE at your company.

We will measure OEE during the period of an 8-hour shift, of a production line which has a production capacity of 1000 pieces/hour.

As an example, we will assume that the line produces parts for only 6 hours (total of 75% of the shift time), produces an average of 700 pieces/hour (performance level of 70%), and that by the end of the shift 168 defective parts have been made (quality 96%).

Although each parameter taken individually may not seem very significant, OEE is at only 50.4% and efficiency is only half of the intended target. The importance of this fact is in what underlies it, as it is now known that the availability is at 75%, performance is at 70% and quality is at 96%. Thanks to these three data we can now carry out improvement actions. For example, to increase availability we would seek to reduce the non-productive time lost due to machine start-ups, changes, breakdowns, delays (waiting periods, etc.), which would increase the figure of the OEE indicator.

Sistemas OEE combines technology and the OEE methodology in order to provide accurate real-time information on the efficiency of your production processes, so you can take appropriate measures to improve the productivity of your business decisions. These are our OEE Products.
