In manufacturing companies, one of the most important factors to consider is OEE.
Having a robust OEE is essential for cost reduction and profit growth through better resource utilization and efficiency improvement.
But what is OEE and how can we apply it in our plant?
OEE (Overall Equipment Effectiveness) is a metric used to measure the efficiency of production equipment. It tells us the production capacity we have in each of the industrial equipment we have in our facilities, as well as placing a marker on wasted times.
Due to the importance of this term, many companies around the world are constantly investing and working with production managers to achieve a better OEE. Some tips for the implementation of OEE could be:
Display OEE data in real time in the production plant.
Previously, the OEE percentage was manually counted and calculated at the end of the day. This leaves us with a significant lag when trying to take corrective action.
Having the OEE indicator in real time allows us to have an effective vision and a correct analysis, to combat the causes of unplanned downtime that continue to affect our productivity.
Encourage individual responsibility to reduce performance losses.
Many small stops can lead to connection losses over long periods of time. When the OEE in real time is not clear, operators may start to accept that every process has downtime instead of looking for solutions for them.
If the data is known and shared with the team, critical and analytical thinking is encouraged to solve problems in the plant.
This new sense of responsibility will start to make sense among workers and will generate a positive effect. As a result, many companies have seen an increase in OEE of 10 to 20%.
Validate investment decisions
The acquisition of production equipment is normally one of the most expensive tasks and in many cases, it ends up being a bad investment.
It is much more economical to maintain and repair machines that are already in use. In addition to this, historical data has shown us that when there are production levels below expectations, it is immediately suspected that the work team is not performing as it should.
With a 40% OEE level, should a company make expenses on new machinery or is it unnecessary? During these difficult times when an informed decision must be made, real-time OEE is essential.
Most of the time we will realize that the equipment is working properly and that in reality we have unused production time. In the best case, we will be able to eliminate variables that could be harming our production
