How to Calculate OEE at the Plant Level?

[@ykruzz1]

I disagree with your Area OEE calculation method of using aggregates. That method will make sense only if the Net Ideal cycle time used on your Performance (P) factor of the OEE calculation is exactly the same across all production lines. If one of the lines makes 1000 parts per hour and the next one makes 50 parts per hour on the same area you will get completely skewed and incorrect results following your aggregate method.

Great point!

It would be great to see a complex example where for instance you have multiple cells in a line with one operator each cell and multiple equipment options. Iam a beginner at this so excuse my ignorance. Love the content currently trying to put together tableau dashboard for the site using data from mes system.

What do you mean by multiple equipment options? Thanks!
