0Overall equipment effectiveness formula
OEE = Availability x Performance x Quality
Availability – How much time did the machine run ?
Performance – How efficiently did it run while it was running ?
Quality – How many good parts did it produce while it was running ?
Availability
A = 100 x (Running time / Available time)
Performance
If you are running a single part,
P = 100 x (Real production / Theoretical production)
If you are running multiple parts,
P = Σ(No. of parts produced x Std. cycle time of part) / Running time.
Quality
Q = 100 x (No. of OK parts produced / Total parts produced)
OEE losses and their meaning
| Type of loss | Meaning | Examples |
|---|---|---|
Not scheduled for production |
Time when the machine is not planned to run |
Non-working shifts, holidays, lunch breaks, tea breaks |
Failure, Idle time |
Time when the machine is planned to run, but is not running. This includes all events that stop production long enough where it makes sense to track a reason for the downtime (typically several minutes). |
Setup, machine breakdown, inspection, accident, no raw material, power shutdown, part unloading and loading. |
Minor stops, Speed loss |
Machine running at lower than normal production rate, and downtimes of duration so small that it does not make sense to track the reason for the downtime |
Part unload/load time that is longer than the standard unload/load time, cycle times that are longer than the standard cycle time, rework |
Scrap |
Number of rejected parts. |
Rejection quantity |
