OEE refers to overall equipment efficiency.

2. What is OEE?
Overall equipment effectiveness (OEE):
 OEE is the gold standard for measuring manufacturing productivity. It simply
identifies the percentage of manufacturing time that is truly productive.
 By measuring OEE and the underlying losses, you will gain important
insights on how to systematically improve your manufacturing process. OEE
is the single best metric for identifying losses, benchmarking progress, and
improving the productivity of manufacturing equipment.
 An OEE score of 100% means manufacturing only Good Parts, as fast as
possible, with no Stop Time. In the language of OEE that means
100% Quality (only Good Parts), 100% Performance (as fast as possible), and
100% Availability (no Stop Time)

3. OEE Calculation Method
OEE= Availability × Performance × Quality
Availability = Run Time / Planned Production Time = TPR / TPL
Performance = Actual Run Speed/Ideal Run Speed = Sactual /Sideal
Quality= Good Count / Total Count = NGood / NTotal
Planned Time TPL
Planned Running Time TPR
Scheduled out Time TUS
Total Time (TT)
Plant Operating Time TPO
Downtime TSD
Scheduled Activities

TPR × Sactual × NGood
TPL× Sideal × N Total
N Total
OEE = NG / (TPL × SR)
OEE [%] =
OEE Direct calculation
NG = Number of good product in cigarettes
SR = Ideal rated speed
TPL = Planned Time (TPR + TUD + TSD)

4. OEE Calculation Example
Item Data
Shift Length 8 hours (480 minutes)
Breaks (2) 15 minute and (1) 30 minute
Downtime 47 minutes
Ideal Speed 1 second per part
Total Count 19,271 qty
Reject Count 423 qty
Planned Production Time = Shift Length − Breaks = 480 mins − 60 min = 420 min
Run Time = Planned Production Time − Stop Time = 420 min − 47 min = 373 min
Good count = Total count − Reject count =19,271 − 423 = 18,848
Availability =Run Time / Planned Production Time=373 min / 420 min= 88.81%
Performance=(Ideal Speed × Total Count) / Run Time = (1 sec × 19,271) / (373 min × 60 sec) =86.11%
Quality=Good Count / Total Count=18,848 / 19,271 = 97.80%
OEE = Availability × Performance × Quality=88.81 × 86.11 × 97.80 = 74.79%
Direct calculation method:
OEE = (Good Count × Ideal Speed) / Planned Production Time
OEE = (18,848 × 1 sec) / (420 min × 60 sec) = 74.79%
