How to link these 2 kinds of simulations?
1) you have a model which you trust - and you have some variations of the input parameters. Then one can find the optimal setting of the input parameters to optimize the outcome - specified by desirability. This approach neglects any uncertainties of the model.
2) with a specific setting of the input parameters, one performs experiments. But the model is not 100% nailed down: You invest at the stock market, you have some model about the possible outcome, but the outcome is not 100% clear yet. This leads to a certain spread of the possible resulting values - an uncertainty.
The second approach can be simulated by adding some additional parameters with variation. The variation of the factor settings is irrelevant for the optimization, but the variation of such additional factors isn't. Is it possible to keep such input factors fluctuating for the Optimization step, to weight the (un)certainty of the predicted value as part of the desirability?

With the desirability defined, click the red triangle next to Prediction Profiler and select Optimization and Desirability > Maximize Desirability. The variation in the factor settings is irrelevant to the search for the optimum factor settings.
