A question for you operations experts.

[LouAvul]

When you're developing the X double bar and R charts, and your samples go up to, say, 15, where do you get your values for the A2, D3 and D4 values?

[Cletus.D.Yokel]

Thailand?

[LouAvul]

BTW, it’s for an operations and supply management class.

A2, D3, D4? I think you just sank my battleship.

Did you Google?

[Cletus.D.Yokel]

Looks like your handle gets the “moose” award. Is your sister okay?

[the invisib1e hand]

Thailand?

exactly.

[Cletus.D.Yokel]

Thanks! Can you keep me up-to-date on this thread? I’m going to go take a shower.

You must make sure you are logged in and that your beeber is set to stune before you can get the values for A2 D3 and D4.

[RetroSexual]

Let me Google that for you.

Oh goody. It's question time YET AGAIN!

Those should be constants. For example, they could be number of processes performed, number of observations, etc.

It's a fairly straight-forward solution.

You need to take the R2 value and combine it with the D2 value.

This should help you with half of your equation.

Finally, the combination of the C3 value with the PO value will give you your final result.

[Billthedrill]

Same place, but your denominator is now 15.

Well, no, I don't actually understand the question, but HERE is something on the topic. Best of luck...

[LouAvul]

I got it. Thanx my man. I googled all around it I guess.

Have a good one.

[mnehring]

the problem is the C3 and PO values are simply translators for the R2 and D2 values. You need to have a constant to trigger the R2 and D2 values to work with the C3 and PO values. Generally, this is the OB1 calculation.
