Putting Dominance-based Rough Set Approach and robust ordinal regression together

► We apply the Dominance-based Rough Set Approach (DRSA) on the results of MCDA methods. ► DRSA completes the decision aiding process started with Robust Ordinal Regression. ► DRSA explains necessary and possible preference relations in terms of decision rules. ► Decision rules are useful for an interactive construction of DM's preferences. ► DRSA can be used in this way with any MCDA method to explain their recommendations.
