Sorry my friend not clear. If any of the purple change,
you will have to reconsider all the other ones.
No problem but for each and any possible combination
that corresponds to a specific recipe, that you may not
have authority to play with unless you are the Lab_Man.
Suggested simplifications attached.

thank J.Giraud for quick reply,

sorry for my unclear statements.
actually I try to get the "LSF" as near to 100 (my target)
by adjusting the "yellow" items and the "SM" "IM" to be within the constraint range.

edit:
done it by the try and error, but I prefer to do it in mathematical way.
