急求OEE资料
哪位大哥有OEE相关资料，请发给我一份，邮箱:workjopnnet@163.com.本人在此谢过！！！！ 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 c**istently used throughout the calculati**.
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
=
=
= 420 minutes
Operating Time
=
=
= 373 minutes
Good Pieces
=
=
= 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%) ­一场地震，生死两难；只道三四险，不知五月难；纵有六双眼，泪也流不完；七颗心儿悬，零八奥运艰；高呼九洲十地华人现，纵使百舸千帆风浪间，也让咱行得万年船！泱泱中华几千年，只是百般无奈斗不过你苍天；十分惨淡，也不知你九重天中住着何神仙，在零八年八月八日还有八十八天时送灾难；但愿七彩祥云现，六月中国保平安，五星红旗永鲜艳;四海升平，三地两岸心连心成一条线！我只想，跪地抬手问苍天，敢应否：下辈子，你做人来我做天！­

呵呵我要了 在找OEE的资料，有好的，可以发SZ2000@189.CN,小弟在此先谢谢了！ 学到了.嘿嘿中........................ 一看到楼主的气势，我就觉得楼主同在社区里灌水的那帮小混蛋有着本质的差别，那忧郁的语调，那熟悉的签名，还有字里行间高屋建瓴的辞藻。 小手一抖，积分到手！ 找到好贴不容易，我顶你了，谢了 前排支持下
