Various multiple-attribute decision analysis approaches have been developed to choose the best fashion design among alternatives, but none of them consider interdependence among their criteria. This study combined the diamond pairwise comparison method to elicit the weights and interaction degrees of a set of criteria and the Choquet integral method for aggregating the evaluation to identify the best design based on the decision-makers’ preferences and prospects. The criteria were determined from input by 10 experts in diverse areas related to fashion design. By implementing the hybrid method in a case example, the efficacy of the proposed approach for evaluating fashion designs is demonstrated.
