Control charts like this are definitely something a number of the plants in my company are interested in as well. I'm working on learning more about this, but I think the idea would be to calculate the UCL, Mean, and LCL values based on logged data and be able to plot and alarm off that.
To complicate things though, I think there would be different UCL/Mean/LCL values based on what material they were producing at the time. For example, from 10-12 today, I'm running material ABC on machine 1 so I want my control chart to be an x days look back at values for this machine and material and I want to see when I'm outside where I should be. We could assume that the "key item" for the chart (e.g. material) would be a tag that Canary would have.
I have more info on this and can elaborate further in the future if that would be helpful.
I think the attached from a previous discussion that Jeff and I had may also help here.
