OEE - Overall Equipment Effectiveness

Production lines that regularly come to a standstill, machines that do not run as planned and low-quality products are common challenges in manufacturing. The OEE (Overall Equipment Effectiveness) provides a solution by evaluating the efficiency of a plant by measuring availability, performance and quality. A precise OEE analysis makes it possible to identify inefficient processes, minimize downtime and maximize productivity.

This is how OEE helps to Production efficiency and to sustainably improve competitiveness.

Definition: What is OEE?

OEE, or Overall Equipment Effectiveness, is a key performance indicator in production technology that evaluates the efficiency and productivity of machines and systems. The OEE value is given as a percentage and shows how productive a machine really is. It indicates how much of the potential productivity is lost due to breakdowns, slow working speed and faulty products.

The OEE is made up of three essential factorsAvailability, performance and quality.

Main factors of Overall Equipment Effectiveness

By analyzing the factors of availability, performance and quality, the efficiency of production systems can be precisely determined and specifically optimized.

  • Availability: This measures how much time the machine is actually running compared to the planned production time. It shows how often the machine is in operation and how often it comes to an unplanned standstill. High availability means fewer unplanned downtimes and more efficient production.
  • Performance: This factor compares the actual production speed with the maximum possible speed. It evaluates whether the machine is working at its optimum capacity or whether there is a loss of speed. Optimum performance shows that production is running smoothly and no time is lost due to slow work processes.
  • Quality: This factor measures how many of the parts produced meet the quality requirements. It shows how many parts are free of defects and do not require reworking. High quality means fewer rejects and rework, which leads to cost savings and more efficient production.

Together, these three factors provide a comprehensive overview of the efficiency and productivity of a production plant. By precisely analyzing availability, performance and quality, companies can identify weak points and take targeted measures to improve production processes.

Calculation of the overall system effectiveness

When calculating the OEE, the three factors mentioned above are set in relation to each other. The general formula for the calculation is

What is a good OEE value?

The OEE value indicates how efficiently a machine or system works. A perfect OEE value would be 100 %, which means that the machine delivers the best possible performance, has no downtime and only produces good products. In practice, however, this is difficult to achieve in the long term.

Good OEE values are 80 % or higher. This is a realistic and achievable value for many companies and shows that the machines are well utilized and efficient.

By calculating and displaying the OEE value, companies can identify where there are losses and which machines are the bottlenecks in production. This helps to make targeted improvements. Machines that are not optimized and often only have an OEE value of 60 % can be improved in order to increase efficiency.

The importance of OEE for the industry

OEE plays a crucial role in industry as it evaluates the efficiency and productivity of production facilities. By analyzing the three main factors - availability, performance and quality - companies can identify weak points in their processes and take targeted improvement measures. A high OEE means that the machines are used optimally, which leads to an increase in overall productivity, a reduction in production costs and an improvement in product quality. This increases competitiveness and contributes to long-term profitability.

 

Advantages of Overall Equipment Effectiveness for your company

 

Improved efficiency and productivity

A high OEE means that machines and systems are optimally utilized. This leads to a reduction in downtime and a maximization of production speed. Companies can therefore manufacture more products in less time, which leads to a significant increase in productivity. Efficiently operating machines mean less downtime and therefore fewer production losses.

Cost reduction

By optimizing the OEE, companies can achieve considerable cost savings. Less downtime and rework means lower production costs. In addition, a higher quality of produced parts leads to less scrap and rework, which further reduces costs. Companies can thus use their resources more efficiently and improve their profit margins.

Competitive advantage

Companies that continuously monitor and optimize their OEE can significantly increase their competitiveness. A high OEE not only means more efficient production, but also a faster response to market changes. Companies can react more flexibly and quickly to customer requirements, which gives them a decisive advantage over the competition.

Sustainability

Improved OEE also contributes to sustainability. Efficiently operating machines consume less energy and resources, which leads to a lower environmental impact. The reduction in rejects and rework also means less waste is produced. Companies that optimize their OEE therefore make an important contribution to environmental protection and sustainable production.
