We propose an alternative method for finding optimal settings of product and process design parameters for the case of an ordinal categorical product/process response. The method utilizes Random Forests for modelling mean and variance of the response at a given set of parameter settings. The method uses different weighting strategies of Random Forest, and it is applied on three case problems. Results obtained are compared with those of previous studies that used the same data sets.
