In an industrial context where competitiveness and efficiency are major concerns, knowing how to calculate OEE (Overall Equipment Effectiveness) has become essential for factories. OEE is a key performance indicator that measures equipment utilization effectiveness, integrating availability, performance, and quality. A poor understanding or underestimation of this indicator can lead to inaccurate decisions directly affecting factory profitability and overall performance.
Erroneous OEE evaluation can stem from several causes. The lack of systematization in data collection, human errors when recording downtime, or approximations in calculating different components often result in significant discrepancies. These inaccuracies impact productivity. For example, poor tracking of extended downtime can subtly affect efficiency, unconsciously increasing production costs and compromising quality.
To address these problems, several levers can be activated. Shop floor digitalization is an indispensable solution, offering real-time monitoring and precise analysis of each production parameter. Solutions like those offered by TeepTrak ensure flawless data collection and analysis, reducing the risk of human error. The integration of continuous improvement methods, such as Lean manufacturing, alongside an OEE tracking system like TeepTrak solutions, can significantly transform production performance and quality.
Let’s take the example of a mechanical parts factory that recently installed an automatic TRS tracking system with TeepTrak. Previously, its teams spent considerable time manually compiling data. Thanks to this new approach, the company was able to precisely identify its main bottlenecks, such as unplanned machine downtime. Within a few months, it achieved a 15% improvement in its TRS, increasing both equipment availability and customer satisfaction through minimized delivery times.
For plant managers and production supervisors, complete mastery of OEE calculation and utilization is an essential lever for driving team and equipment performance. Starting a structured project around TRS/OEE, leveraging tools like TeepTrak, is a concrete response to modern industrial challenges. By optimizing OEE, companies can not only reduce costs but also improve quality and sustainably strengthen their competitive position.
FAQ
Question 1: How do you calculate OEE for a specific machine?
OEE calculation is based on three components: availability, performance, and quality. Each value is calculated separately before being multiplied to obtain total OEE.
Question 2: What is the impact of low OEE on production?
Low OEE indicates inefficient equipment utilization, which can lead to high production costs, reduced quality, and loss of market competitiveness.
Question 3: Where should you start to improve OEE?
Begin with a thorough analysis of downtime and performance losses. Use digital tools like TeepTrak for precise monitoring and to implement targeted corrective actions.
