I don't think Quality of the parts produced can be taken out of equation in calculating OEE. In fact, what is effectiveness without Quality?
8balluk,
If the parts are lying in rack for inspection, which I assume is normal for your process, why not measure OEE at an interval that is suitably fixed to accomodate inspection results.
We have a similar issue in my company, I believe that Quality is integral to OEE as it is no good your machines producing 24/7 if they are not producing a quality product, this will be highlited in the OEE result and can investigated and coutermeasured. We do not run our OEE on a daily basis but a weekly, some of our product can take upto 5 days to get through the complete process. At the end of the week all the OEE is displayed on the shop floor at the machine concerned and a countermeasure plan put in place with the results to improve the next time that product is run.
To avoid operators "helping" the figures we have hourly white boards that are updated by the operators on the hour and audited throughout the day. To ensure all numbers match, with this way all issues are spotted within an hour and operators are aware they can not make figures suit.
