Overall Equipment Effectiveness

Overall Equipment Effectiveness (OEE) is a commonly used measuring instrument and tool to measure the performance of the machines and production process, and to directly see the effectiveness. OEE is measured by combining Availability (A), Performance (P) and Quality (Q). It helps to identify potential losses en to understand where in the process it needs improvement. If you have invested in expensive machines, it is important that they are used effectively.

With OEE you calculate the ratio between theoretical maximum output and real output. When there is a difference, it helps you to detect where that difference is caused. OEE checks three things:

Availability

Availability

Is the machine running when it is planned to run?

 

 

Performance

Performance

Is the machine running on theoretical maximum speed?

 

 

Quality

Quality

Are high-quality products produced?

Everytime the answer is no, you need to find out what the cause is. The OEE per production line is shown real time. To generate a trustworthy OEE number, on which companies manage, it is essential to get correct input from the work floor. The OEE calculation is linked to the ProMISe downtime registration system. Because of the real time display and quick insights in production and downtime it is possible for everyone to intervene timely.

To use OEE more effectively ProMISe categorises downtime. Different kinds of downtime is linked to factors that determine OEE. Then it is linked to one of the categories. This way it becomes more quicky insightful for the manager as to where the improvement potential lies: more in technical area or organizational area.

The universal character of OEE makes it for everyone understandable. Operators themself can intervene quicker, managers kan manage better based on the numers. It also makes it possible to bechmark against other companies or other business units.

Improving your OEE by means of continuous improvement.
