Calculation of the Oee Index Overall Equipment

Oee is an acronym for the term overall equipment effectiveness . In portuguese, we can translate to general efficacy of equipment. This concept is closely linked with the concepts of lean manufacturing and aims to optimize your production line as much as possible. Basically, this is an indicator that will help you understand the effectiveness and productivity of your production line by taking into account 3 perspectives: productivity availability quality therefore, the classic formula for calculating the oee indicator is: oee% = availability% * productivity% * quality% now, let’s find out below how to get to each of these intermediate indicators. 1. Productivity calculation this indicator wants to assess whether that specific machine is producing as expected.

You Want to See How Much Production

It has achieved within the expected time in relation to its full potential. “productivity% = (actual production cycle x actual production hours)/(estimated production cycle x planned production hours) * 100%” practical example: prime light let’s say you are evaluating a forklift. You have planned philippines phone numbers for her to stack 3 boxes per minute and her default production day is 400 minutes. So you expect to stack 1200 boxes a day. However, you’ve gauged that she only actually worked 370 minutes and was only able to stack 2.6 boxes per minute. Therefore, only 962 boxes were stacked that day. So your productivity indicator will be calculated by 962/1200 = 80% 2.

Availability Calculation This Indicator Aims to Measure

How much the machine was actually available for production. So this takes into account both the time it was planned to run and the amount of time it actually ran. Logically, the time available will be directly influenced by scheduled and unscheduled downtime/maintenance. “availability% = ((producing time / available time practical example. Following the forklift case, let’s say you calculated at the beginning of your day that it. Despite having 400 minutes for production, would need to stop 100 minutes for maintenance. However, throughout the day, its maintenance took 150 minutes. So her planned available time was 300 minutes, but she actually only produced 250 minutes.
