Reproduce exact same DOE table created by another person

1. Is it possible to reproduce exact same DOE table created by another person with same rows & column with same max/min (+1/-1) combination for 8 Factors/Inputs and 1 Response/Output using Custom Design in JMP 14?

2. Every time I create a DOE table with exact same order/parameters/values of Factors, the run orders for the table come different with different setting of input values/combination even with Non-Random selection. What could be the reasons? Can I reproduce my own table created few minutes ago with exact same run orders having same input +1/-1 combination for all 8 factors?

 

Appreciate your feedback.

Regards,

Pramod

 Try setting the random seed in Custom Design:

Custom Design uses a random search to create designs. See JMP help documentation here.

 

I hope this helps.

Hi Phil
Thanks for your response. I tried Custom Design>Set Random Seed. But I am not able to get the exact same matrix when I repeat to make DOE table again, even with 'Keep the Same' selection under Run Order drop down options.
With regards,

Hmmm....?

I find that surprising. This might sound stupid but did you set the same random seed?

Can you attach an example of the kind of design you are creating please?

Thanks for you quick response Phil. How do I attach any example or document?

Click "Reply" (not "Quick Reply") and there is a drag and drop zone beneath the "Body" box to drag and drop files to attach.

Also, please let me know what version of JMP you are using.

Re: Reproduce exact same DOE table created by another person

Perhaps I don't understand the issue...Let's say you are creating a fractional factorial on the 8 factors (2^8-4).  DOE>Custom Design.  Put 8 in the Add N Factors window, Select the Add Factor drop down and select continuous.  This will add 8 (X1-X8).  Select continue. On the next window, select Make Design.  On the next window select the Run Order drop down and select any option except Randomize ( Keep the Same, for example).  The select Make Table.  This will give you a JMP Table with 8 columns of X's (X1-X8) and 1 Y column and 16 rows.  If you repeat this, you will get the exact same matrix every time.

You got it. That is what exactly I am doing. But, I am not able to get exact same matrix when I repeat to make DOE table again. Thanks for your help anyhow.

Re: Reproduce exact same DOE table created by another person

For a simple 2-level screening problem like Statman’s example I would expect you to get the same design each time. When problems get more complicated you will not get the same each time.
