The OEE (Overall Equipment Effectiveness) is a key indicator to measure the efficiency of a machine. The plant OEE provides information on the productivity and efficiency of the plant’s production processes. In the same way, it allows to know those aspects that are not favouring productivity. Among these are identified stoppages, breakdowns, quality problems, etc.

It will allow us to know where the production processes are in terms of efficiency and productivity, and from this point, work to improve them and achieve the best results.

To calculate OEE, we rely on three concepts: availability, performance and quality.

 

Availability is obtained by dividing the operating time by the planned production time.

 

Yield is the division between what is produced in operating time (whether good or bad) and what would have been produced in an ideal production time.

 

Finally, quality is the number of good parts in relation to the total number of parts produced.

 

All these concepts are expressed as a percentage, obtaining a result between 0% and 100%, the latter being the optimum result.

Why is a MES System important for OEE?

 

Thanks to the implementation of an MES system, a complete analysis of the OEE can be carried out, in order to know the points that are affecting productivity, both positively and negatively, and to influence them in order to obtain the best results.

In this way, we can reduce unplanned downtime. We will also be able to have a maintenance plan that helps to adjust times and reduce the occurrence of breakdowns. This will have an impact on improving availability.

We will be able to improve the speed of production by obtaining information in real time and with a good planning system that connects different departments. In this way, all operators will know the necessary information and will be able to prevent unexpected stoppages, helping to optimise plant performance.

Finally, we will reduce the “bad” products by identifying the most critical points in production and working on them to improve their performance. This will improve the overall quality of the results.

How can Geprom help you to visualise and improve OEE?

 

Today, there are many companies that have an OEE below 70% and thus have great room for improvement in their productivity and efficiency.

Failure to take plant OEE into account can lead to a major loss of profitability and efficiency. Instead, performing OEE systems analysis can ensure that you improve your productivity and efficiency.

At Geprom, we are specialists with more than 25 years of experience in the Industry 4.0 sector. With the implementation of our in-plant MES systems, we have helped companies in multiple industries to significantly improve their OEE.

We offer the possibility of monitoring the entire production line to have real-time information and be able to have a high traceability of any type of product, in order to optimise your production process to the maximum.

In this way, we not only improve the OEE but also manage to reduce many production costs.

If you want to digitise your factory, Geprom can help you.
