RT Book, Section T1 Single-Peakedness in Weighted Aggregation of Fuzzy Opinions in a Fuzzy Group A1 Montero, Javier A2 Kacprzyk, Janusz A2 Fedrizzi, Mario AB In this paper it is considered a formal approach to the problem of aggregating individual opinions in a fuzzy group, when alternatives can be represented in a real hyper-space and each individual defines his/her fuzzy set of non rejectable alternatives. 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.
