Q: I have been reading in different sources about the OEE measurement and I have not been able to find any concrete agreement about what the value for OEE should be. Could you please give me any references?
I have read that there is no common agreement but that it is generally suggested that bellow 65% should be considered unacceptable, since it represents a very low competitiveness and a great number of economic losses. A value between 65 and 75% is considered as regular, only acceptable if it is being improved. A value between 75 and 85 % means an acceptable level with slight economic losses and which can be easily improved to World Class levels. A value between 85 and 95 percent is considered as good and equals World Class values; it represents a high level of competitiveness. And finally, a value above 95% is considered as excellence; an excellent competitiveness and World Class values.
Q: Some of our machines are not being used every day on the demand of the product. So, I don’t evaluate those machines when they remain idle. But, as per my boss, those idle machines should also be evaluated (i.e. OEE =0) and should be presented in monthly graphical reports. Is it correct to calculate OEE of those machines while they are not running?
Q: My boss wants me to calculate and present a graphical OEE representation on a monthly basis. I present this as I do with the daily data. I calculate the monthly OEE by taking the average of the daily OEE’s.
Is it alright to present a monthly OEE of the machines by calculating the average of the daily OEE’s in a month?
Q: I have been asked by my boss to evaluate the performance of the Machines in our factory and I found the implementation of OEE is the best way. Now I have some questions about how to define OEE, I have been following this website which helps me a lot.
Q: Can OEE be used or adapted for use in the oil and gas industry? Are there ay concrete examples of how the metric can be used successfully, either off or on-shore?
Q: My OEE goes over 100%. What did I do wrong?
Q: What is the availability (or OEE) of a shift when the shift is not completed yet?
Q: I am a bit confused about Loading Time, Shift time, Potential production time. How do they relate? Or are they all the same?
