Eliciting ratio preferences for the analytic hierarchy process with visual interfaces: A new mode of preference measurement

Although verbal and numerical scales are commonly used in the Analytic Hierarchy Process for pairwise comparisons, new experiments with computer-based visual tools confirm that ratio preferences can be effectively and efficiently elicited using adjustable visual tools and simultaneous comparisons, as well. Such an improved approach shows promise in the design of a new class of multi-criteria decision support system both for individual and group decisions.
