Characterization theorems are given, and it is also shown that Montero's rationality and standard ethical conditions propagate under hierarchical aggregations.engjournal articlehttps//doi.org/10.1016/0888-613X(94)90012-4http://www.sciencedirect.com/science/article/pii/0888613X94900124open access519.8Aggregation rulesFuzzy preferencesGroup decision-makingInvestigación operativa (Matemáticas)1207 Investigación Operativa
