MEASURING EQUIPMENT EFFECTIVENESS

Overall Equipment Effectiveness (OEE) can be measured using the formula:

OEE formula

A high level of effectiveness can be achieved only when all three rates are high. For example, a company has measured its rates as follows:

Availability = 85% : Performance = 95% : Quality = 91%


The above rates may not seem too bad, but look what the overall figure is:

OEE = A x P x Q = 85% x 95% x 91% = 73.5%

It can be seen that to achieve a high OEE requires excellent rates in all three elements!

A world class standard would be OEE greater than 85%
