Wouldn’t it be amazing if all equipment would operate all the time at full capacity producing good quality product?
Overall Equipment Effectiveness is a measure of what you actually made over what you could have made, in theory, over that timeframe. The difference between the ideal (theoretical) and actual situation is due to losses categorised into various metrics that provide you with excellent data to enable you to target areas of improvement.
Reduce or eliminate the six losses of OEE to improve your score.
Understanding and categorising efficiency loss into six losses pinpoints area of focus that will improve the efficiency of the equipment. These six losses contribute to your OEE score and are categorized under Availability, Performance and Quality Loss.
What are the six losses of OEE?
- Planned downtime or external unplanned event
- Speed loss
- Breakdowns (>5mins)
- Minor stops (<5mins)
- Production rejects
- Rejects on start up
PLANNED DOWNTIME / EXTERNAL UNPLANNED EVENT
BREAKDOWN LOSS ( > 5 MINS )
MINOR STOP LOSS ( < 5 MINS )
REJECTS ON START UP
Planned Downtime / Total Production Time
Major Fault Time / Total Production Time
Minor Fault Time / Total Production Time
(Output / Ave Speed X Total Production Time)
(Output / Rated Speed X Total Production Time)
Rejects In Prod / (Good Output + Total Rejects)
Rejects On Start Up / (Good Output + Total Rejects)
We combined the use of LineView and the Coke Way to yield a 20% OEE improvement at CCE Dongen over an 18 month period – the ROI was 16 weeks."
