benefits from calculating overall equipment effectivness
- 2. What is OEE?A System That..Is used to measure and understand performance & effectivenessEquipment Processes
- 3. What do we mean by OEE?A measurement system that..Helps us to understand the current process statusSupports production planningFacilitates improvement plansSupports investment decisions
- 4. Key factors of OEEAvailabilityPerformanceQuality
- 5. 1. AvailabilityMeasures “Productivity Losses” from breakdown times:Remaining time is called “Operating Time” Availability is the ratio of Operating Time to Planned Production Time.
- 6. 2. PerformanceMeasures “Productivity Losses” from slow cyclesThe remaining time is called Net Operating TimePerformance is the ratio of Net Operating Time to Operating Time
- 7. 3. QualityQuality takes into account Quality LossThe remaining time is called Fully Productive TimeQuality is the ratio of Fully Productive Time to Net Operating Time
- 8. OEE..Takes into account all the three factorsAvailabilityPerformanceQualityOEE = Availability x Performance x Quality
- 9. Six big lossesBreakdownsSetup and adjustmentMinor stopsReduced speedsStart Up rejectsProduction rejects
- 10. How OEE attacks the six big losses
- 11. Calculating OEEAvailabilityAvailabilty takes into account Down Time Loss, and is calculated as:Availability = Operating Time / Planned Production Time Performance Performance takes into account Speed Loss, and is calculated as:Performance = Ideal Cycle Time / (Operating Time / Total Pieces)QualityQuality takes into account Quality Loss, and is calculated as:Quality = Good Pieces / Total Pieces
- 12. Calculating OEEOEEOEE takes into account all three OEE Factors, and is calculated as:OEE = Availability x Performance x Quality
- 13. World Class OEE
- 14. Importance of OEE in the Strategic planning processOEE can save companies from making wrong investment decisionsOEE can also be used to ensure that equipment suppliers deliver what they promised!In essence, OEE is the missing link between money and machines!
- 15. OEE gives you answers to the following questionsHow confident were you about the investment when you signed the cheque ?Exactly how well is the new plant performing now?Do you use an appropriate measure of machine performance ? In the absence of the OEE measure, how will they ever know?
