Calculating OEE
The Formulas
As described in World Class OEE, the OEE calculation is based on the three OEE Factors: Availability, Performance, and Quality. Here's how each of these factors is calculated.
Availability
Availability 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)
Ideal Cycle Time is the minimum cycle time that your process can be expected to achieve in optimal circumstances. It is sometimes called Design Cycle Time, Theoretical Cycle Time or Nameplate Capacity.

Since Run Rate is the reciprocal of Cycle Time, Performance can also be calculated as:
Performance = (Total Pieces / Operating Time) / Ideal Run Rate
Performance is capped at 100%, to ensure that if an error is made in specifying the Ideal Cycle Time or Ideal Run Rate the effect on OEE will be limited.
Quality
Quality takes into account Quality Loss, and is calculated as:
Quality = Good Pieces / Total Pieces
OEE
OEE takes into account all three OEE Factors, and is calculated as:
OEE = Availability x Performance x Quality
It is very important to recognize that improving OEE is not the only objective. Take a look at the following data for two production shifts.

OEE Factor       Shift 1       Shift 2
Availability       90.0%       95.0%
Performance       95.0%       95.0%
Quality       99.5%       96.0%
OEE       85.1%       86.6%

Superficially, it may appear that the second shift is performing better than the first, since its OEE is higher. Very few companies, however, would want to trade a 5.0% increase in Availability for a 3.5% decline in Quality!

The beauty of OEE is not that it gives you one magic number; it's that it gives you three numbers, which are all useful individually as your situation changes from day to day. And it helps you visualize performance in ** terms - a very practical simplification.
Example OEE Calculation
The table below contains hypothetical shift data, to be used for a complete OEE calculation, starting with the calculation of the OEE Factors of Availability, Performance, and Quality. Note that the same units of measurement (in this case minutes and pieces) are consistently used throughout the calculations.

Item       Data
Shift Length       8 hours = 480 min.
Short Breaks       2 @ 15 min. = 30 min.
Meal Break       1 @ 30 min. = 30 min.
Down Time       47 minutes
Ideal Run Rate       60 pieces per minute
Total Pieces       19,271 pieces
Reject Pieces       423 pieces

Planned Production Time
= [Shift Length - Breaks]
= [480 - 60]
= 420 minutes

Operating Time
= [Planned Production Time - Down Time]
= [420 - 47]
= 373 minutes

Good Pieces
= [Total Pieces - Reject Pieces]
= [19,271 - 423]
= 18,848 pieces

Availability       =       Operating Time / Planned Production Time
      =       373 minutes / 420 minutes
      =       0.8881 (88.81%)

Performance       =       (Total Pieces / Operating Time) / Ideal Run Rate
      =       (19,271 pieces / 373 minutes) / 60 pieces per minute
      =       0.8611 (86.11%)

Quality       =       Good Pieces / Total Pieces
      =       18,848 / 19,271 pieces
      =       0.9780 (97.80%)

OEE       =       Availability x Performance x Quality
      =       0.8881 x 0.8611 x 0.9780
      =       0.7479 (74.79%)

自从论坛改版之后，我就已经心灰意冷，对论坛也没抱什么希望了，传说已经幻灭，神话已经终结，留在论坛还有什么意思。没想到，没想到，今天可以再睹楼主的风范，我激动得忍不住就在屏幕前流下了眼泪。是啊，只要在楼主的带领下，论坛就有希望了。我的内心再一次沸腾了，我胸腔里的血再一次燃烧了。
