Based on the above response modeling and ranges of the factors (4<AC<5;
4<AV<7; 30<T<50; 5<Temp<25), I want to determine levels of the AC, AV, T,
and Temp to have the Maximum value of KIC. Because the stationary point is
an outside region of experiments, I try the desirability packages in R, but
it does not work because these packages almost focus on different responses
rather than variables.
I believe that there is a package which can solve this problem because,
with Minitab, the result using the desirability function can be shown in
If anyone has any experience practicing the desirability function or
suggests any potential package, I appreciate your support and help.
