Abstract: Four multiresponse optimisation problems were simulated under the RSM framework to represent real-life situations and provide a fair basis to compare the performance of optimisation criteria built on different approaches. Different response types, feasible regions, number of responses and variables as well as adverse variance conditions were considered in each problem. An unusual graphical representation of the results provides useful information about working abilities of tested criteria. To help decision-maker in making more informed decisions about solution selection, performance metrics usefulness is also illustrated.

Keywords: bias; decision making; loss function; multiresponse optimisation; performance metrics; optimal solutions; response surface methodology; RSM; robustness; variance; simulation; criteria evaluation.
