Arrow (1951, 1964). In particular, it is postulated that the main reason for the discouraging impossibility theorems is neither in the domain of admissible preferences nor in the concept of solution, but in the underlying idea of rationality under all crisp approaches. Noncomplete irrational aggregations are possible under a fuzzy approach, so that Arrow's classical theorem should be understood just as an impossibility of getting complete rational aggregationsengbook parthttp://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=258668&abstractAccess=no&userType=insthttp://ieeexplore.ieee.org/open access519.226Decision theoryFuzzy set theoryTeoría de la decisión1209.04 Teoría y Proceso de decisión
