Abstract

Pairwise comparisons have been a long standing technique for comparing alternatives/criteria and their role has been pivotal in the development of modern decision making methods. Since several types of pairwise comparison matrices (e.g. multiplicative, additive, fuzzy) are proposed in literature, in this paper, we investigate, for which type of matrix, decision makers are more coherent when they express their subjective preferences. By performing an experiment, we found that the additive approach provides the worst level of coherence.
