it's a straightforward measure: as explained previously, if your OEE is 75% then you are only achieving 75% of the potential output capacity.Anyway let me try to ask like this:
AVA%*PER%*QUA% = OEE% = is about the "overall" yes but what does it mean? tells you that ... ? OEE of 75% tells you that 75% of .... ....
this formula is nonsensical. adding the 3 measures values is not the correct way - mathematically - to determine equipment utilization...they are like standard deviations. they must be combined as in the above formula. so dividing an incorrect number by 3 tells you nothing as well. this formula doesn't give you the average. You will need to calculate the average availability and the average performance over some period of time and then multiply the 3 proportions together to get the average OEE...(AVA+PER+QUA)/3 = is about ? tells you that - average yes, but means that ...
