In this example

• Shift time:                                         500 min
• Production  time:                           100 min
• Waiting:                                            400 min
• Max output:                                     100min x 1000 pcs = 100.000 pcs
• Set speed                                          800 pcs/min
• Expected output:                            100min x 800 pcs = 80.000 pcs
• Actual Output:                                 50.000 Good Product
  •                                                  6.000 Rework
  •                                                  3.000 Scrap

Result

1. Availability 20% (100min/500min)
2. Performance: 60% (Actual output / Maximum Output)
3. Quality: Good Product / (Good+Rejects) = 83%
4. OEE = 20% x 60% x 83% = 10%
