Elicitation of Criteria Weights Maximising the Stability of Pairwise Outranking Statements

We propose an indirect approach for assessing criteria‐importance weights from overall outranking statements that a decision maker may acknowledge in a multiple‐criteria decision aid process. Our approach takes advantage of the bipolar characteristic valuation of the overall outranking and the stability of its associated median‐cut, crisp outranking relation. Numerical criteria‐importance weights are inferred with the help of a mixed‐integer linear programming model for which we present tests results under different configurations and tunings.
