Profiler Set-Up: Output Variable (Y) Importance

In multiple y optimization in a profiler, each y requires it's own desirability function/response goal (max, min, target).  But to combine them into a single desirabililty function you have to assign an Importance value to each y.  The default value = 1.  How does this work? What is the scale?

Thanks, in Advance,

Re: Profiler Set-Up: Output Variable (Y) Importance

The importance does not NEED to be assigned, since the default is 1. However, the importance is just that: importance. So you can determine the scale. Suppose you have Y1 and Y2. If Y1 has an importance of 1 and Y2 has an importance of 2, then Y2 is twice as important as Y1. You would get exactly the same result if you specified importances of 0.5 and 1, 4 and 8, 100 and 200. The scales are relative.
