What is OEE and how to calculate it? A practical guide to improving industrial performance

Overall Equipment Effectiveness (OEE) is a key industrial performance indicator that measures the overall efficiency of production equipment. For plant managers and performance managers, understanding and optimizing OEE is crucial to improving productivity and reducing costs. Yet many plants struggle to systematically track this indicator, which compromises their competitiveness. Calculating OEE may seem complex, but it is essential for identifying and eliminating performance losses.

There are many causes of poor OEE performance: unplanned downtime, low production speed, or quality problems. These factors have a direct impact on plant productivity and profitability. If downtime increases, overall efficiency falls and production costs rise, compromising margins. Improving OEE requires a precise analysis of the root causes of these inefficiencies.

One of the main levers for improving OEE is the digitalization of the shop floor. With solutions like TeepTrak, plants can monitor their performance in real time, detect breakdowns early and optimize resource utilization. Continuous improvement methods such as Lean Manufacturing and Total Productive Maintenance (TPM) are also crucial to structuring an effective TRS/OEE monitoring program.

A concrete example of OEE improvement is an automotive production line. Thanks to the implementation of a real-time monitoring system, the plant was able to reduce downtime by 15% and improve product quality. Real-time data analysis identified the main bottlenecks and enabled immediate corrective action to be taken. This approach not only optimized the OEE, but also raised the team’s awareness of the importance of continuous improvement.

To begin an OEE improvement project, it’s essential to start with a thorough assessment of the current state of production operations. Prioritize the areas where the impact will be most significant. With TeepTrak, plants benefit from advanced tools for real-time OEE monitoring and downtime analysis, facilitating decision-making and continuous improvement. Rigorous measurement and monitoring of OEE are essential for any company wishing to maintain its competitiveness in the manufacturing industry.

FAQ

Question 1: How does calculating OEE impact productivity?

Calculating the OEE helps identify performance losses in a plant. By measuring this indicator, companies can target and correct inefficiencies, directly improving productivity and reducing unplanned downtime.

Question 2: What are the main components of the OEE calculation?

OEE can be broken down into three main factors: availability, performance and quality. These components analyze equipment uptime, production speed and end-product quality, respectively.

Question 3: Where do you start to improve your OEE?

Start by identifying the main sources of lost performance. Use a real-time tracking tool like TeepTrak to analyze the data and implement continuous improvement practices such as Lean Manufacturing.
