DoE disallowed combination script/filter not working as expected

mvanderaa1 — Thu, 08 Jun 2023 21:09:36 GMT

Hi, I keep getting runs in my design that should be restricted by my disallowed combination script. Or perhaps I'm not understanding the syntax. I have tried it both using the filter and as a script.

An example where the combination of S2S==5.8 & L2L>4 is not allowed, yet I get multiple runs that do not conform to that restriction (run 4, 5, 10). I attached the script for the design as well.

I was able to reproduce the problem, even after I removed the unnecessary L2L <= 5.5 comparison. I suggest contacting JMP Technical Support (support@jmp.com) about this problem. Please reply here with their answer.

It happens sometimes with the numeric representation that 5.8 isn't "exactly" 5.8 when being checked by the designer.

If you replace S2S == 5.8 in the disallowed combination with a "fuzzy equals", like Abs( S2S - 5.8 ) < 0.001, it should work as expected.

We eventually hope to add checks internally to watch out for cases like this.

This seems to do the trick, thanks
