Understanding and improving OEE with the overall equipment efficiency formula

In modern manufacturing, the pressure to improve productivity has never been greater. One of the best tools for assessing and improving operational efficiency is Overall Equipment Effectiveness (OEE). However, many industrial managers do not fully understand the formula for overall equipment effectiveness, which can lead to sub-optimized performance and wasted resources. A clear understanding of OEE is crucial to identifying process inefficiencies and maximizing the value of equipment investments.

Problems associated with a poor understanding of OEE often include misdiagnosis of the causes of downtime and low productivity. Misinterpretation of efficiency indicators can also lead to counter-productive improvement strategies. By neglecting aspects such as availability, performance and quality, plants risk missing production targets, increasing operating costs and reducing overall profitability.

To overcome these challenges, the use of digitalization solutions such as TeepTrak enables real-time monitoring of performance through automated measurement and access to accurate analytical data. The adoption of continuous improvement methods, such as Lean Manufacturing and Total Productive Maintenance(TPM), also boosts efficiency. Tools such as PerfTrak OPC UA are essential for collecting and analyzing key indicators, providing exhaustive visibility of the production floor.

A concrete example can be seen in an automotive parts manufacturing plant. Using the OEE, the supervisor was able to identify that the main cause of lost efficiency was linked to frequent line stoppages. Using TeepTrak solutions for real-time downtime analysis, the plant decided to carry out targeted optimization of its maintenance process. The result was a drastic reduction in downtime and a 15% gain in overall efficiency.

For manufacturers wishing to exploit the full potential of OEE, it is essential to start with an accurate assessment of the current situation. Effective management of continuous improvement, supported by the digitization of production data with TeepTrak, enables significant gains to be made in productivity and profitability. Launching a structured TRS/OEE project is the key to transforming analyses into concrete, lasting improvements.

FAQ

Question 1: How is OEE calculated?

OEE is calculated by multiplying three factors: availability, performance and quality. Each of these factors reflects an essential dimension of production process efficiency.

Question 2: What is the impact of misinterpreting the OEE?

Misinterpretation can lead to erroneous decisions regarding necessary improvements, resulting in unnecessary expenditure and prolonged inefficiency in industrial operations.

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

Start by assessing your current processes using tools like TeepTrak for real-time analysis, and identify the main sources of lost efficiency.
