So I need just to play with it a little bit more to get used to it.
Yeah I noticed the techinal and mathematical terms in a preview.
@markbailey thanks for you recommendation. I will look into it aswell.
Now that people are still using this subject! A different question but with the same scenario.
I can open another discussion if that is more easier....
Same scenario but this time the ratio is the only constant value.
C1 liquid reacts with C2 liquid in a ratio 100:75
So the formula will be: 4*C1 liquid = 3 C2 liquid
As far as I understand from https://www.jmp.com/en_in/events/ondemand/mastering-jmp/mixture-designs.html
The constrain will become:
4*C1 liquid -3 C2 liquid </= 0
4*C1 liquid -3 C2 liquid >/= 0
The other constrain is just like last time, that all ingredients for component 1 is 50% and all the ingredients for component 2 is 50% of the total blend.
The picture is a little bit small now... sorry. (just to be sure it can also be found in the appendix.
For some weird reason I get now "Optimal designer failed to converge."
Have I filled in something wrong here?
When you start constraining your components this much and JMP fails to find a design, my first question is always: do you even have a feasible experimental region left? Look at your component constraints along with these additional constraints. Is there a viable region to experiment over?
I understand, I had something in my mind and I probably need to rewrite the components values.
I'm sure it is possible, I just need to check my factors again.
I have simplify it and then it was possible. See picture down here.
Due to the ratio there is not really a plane, but more like a line were the optimal can be reached.
That line is in an area of 0 by 0.5.
C1 liquid and C2 liquid are reacting with a ratio of 100:75. In this example in a range of 0 bij 0.5.
(0 is not really what I want, because it needs to react, but I wanted to see if it was possible.)
The optimal will be checked with every Filler ingredients. So GGREY006A... etc.
So how I see it, JMP can check a line area.
And yes I noticed my ratio fault here.
It's now C1 liquid : C2 liquid
75 : 100
And I wanted C1 liquid: C2 liquid
100 : 75
I need to swap the 4 and the 3 around.
I'm going to play a little bit more with JMP.
Made it!
Yes, John A. Cornell is recognized as one THE experts on mixture designs. I recommend his papers " Embedding Mixture Designs inside Factorial Experiments", "Mixture Experiment Approaches: Examples, Discussion, and Recommendations". Also Ron Snee has some good papers "Screening Concepts and Designs for Experiments with Mixtures" and Design and Analysis of Mixture Experiments".
Enjoy!
