What is OEE (Overall Equipment Effectiveness)?
The biggest problem in production lines is not knowing how efficiently the machines "actually" work. The factory owner thinks the machine has worked for 8 hours, but due to micro-stops, speed drops, and waste, the machine has actually only produced 4 hours of value.
The OEE (Overall Equipment Effectiveness) metric is used to find these hidden losses. In smart (Industry 4.0) packaging lines, OEE is the gold standard of performance.
3 Core Components of OEE
The OEE calculation consists of multiplying three factors: Availability x Performance x Quality
- Availability: How long the machine works during the planned production time.
- Performance: How close the machine gets to its theoretical maximum speed while running.
- Quality: How many of the produced packages come out sound (without waste).
OEE Formula: Availability (%) × Performance (%) × Quality (%) = OEE (%)
What Should Be the World-Class OEE Target?
- 100% OEE: Perfect Production (Zero downtime, zero defects, maximum speed - Theoretical only).
- 85% OEE: World Class. It is the target of ambitious manufacturers.
- 60% OEE: Average. It means there is still a great potential to be improved.
- 40% OEE: Low. There is serious waste and hidden costs (downtime) in production.
As Dr Mach, we produce Industry 4.0 compliant lines with integrated PLC and SCADA, transferring OEE data to the cloud in real-time and allowing you to monitor the factory from your mobile phone.
