A novel technique based on the Law of Comparative Judgment for quality-related problems
A relatively diffused problem in the quality engineering/management field is that in which a set of judges express their individual (subjective) judgments on a specific attribute of some objects and these judgments have to be fused into a collective one.
The goal of this paper is to develop a new technique that combines the Thurstone’s Law of Comparative Judgment with an ad hoc response mode based on preference orderings. This technique allows to express the collective judgment of the objects on a ratio scale and is applicable to a variety of practical contexts.
