On one hand, weighted aggregation rule for consensus opinion is axiomatically justified. On the other hand, it is shown a sufficient condition for the stability of such consensus solution.engbook parthttps//doi.org/10.1007/978-94-009-2109-2_15http://link.springer.com/chapter/10.1007/978-94-009-2109-2_15open access519.8Aggregation rulesGroup decision makingFuzzy opinionsInvestigación operativa (Matemáticas)1207 Investigación Operativa
