DIES (SMED)

8. OVERALL EQUIPMENT
EFFECTIVENESS
(OEE)

9. What is Overall Equipment Effectiveness
(OEE)
 OEE measures the efficiency of the machine during its loading time.
 OEE is calculated from three underlying factors:
 Availability
 Performance
 Quality
 Each of these factors represents a different perspective of how close your
manufacturing process is to perfect production

10. OEE = Availability x Performance x Quality
 Availability
• a comparison of the potential operating time and the time in which the machine is actually
making products.
 Performance
• a comparison of the actual output with what time the machine should be producing in the
same time.
 Quality
• a comparison of the number of products made and the number of products that meet the
customer’s specifications.

11. Why is OEE important?
 OEE is expressed as a percentage
• it gives a complete picture of the machine’s “health”
 Effectiveness focuses on the equipment, not the person
 OEE measurement helps us to direct improvement efforts on the equipment or
process

12. Approaches to improve OEE
 5 Why Analysis
 Autonomous Maintenance
 Focused Equipment & Process Improvement
 Quick Changeover
 Poke Yoke
 P-M Analysis

13. OEE Calculation
Availability (Down Time Losses) =
Time available for production −Downtime
time available in production
x 100%
Performance (Speed Losses) =
Ideal Cycle Time x Processing Quantity
𝑂𝑝𝑒𝑟𝑎𝑡𝑖𝑛𝑔 𝑇𝑖𝑚𝑒
x 100%
Quality Yield (Quality Loss) =
Total Processed Quantity −Defect
Total Processed Quantity
x 100%
OEE = Availability x Performance x Quality Yield
