1. Rationalization of indecisive choice behavior by majoritarian ballots

Abstract

We describe a model that explains possibly indecisive choice behavior, that is, quasi-choices (choice correspondences that may be empty on some menus). The justification is here provided by a proportion of ballots, which are quasi-choices rationalizable by an arbitrary binary relation. We call a quasi-choice $s$-majoritarian if all options selected from a menu are endorsed by a share of ballots larger than $s$. We prove that all forms of majoritarianism are equivalent to a well-known behavioral property, namely Chernoff axiom. Then we focus on two paradigms of majoritarianism, whereby either a simple majority of ballots justifies a quasi-choice, or the endorsement by a single ballot suffices - a liberal justification. These benchmark explanations typically require a different minimum number of ballots. We determine the asymptotic minimum size of a liberal justification.

45. Complemental Fuzzy Sets: A Semantic Justification of <inline-formula><tex-math notation="LaTeX">$q$</tex-math></inline-formula>-Rung Orthopair Fuzzy Sets

Author

Alcantud, Jose Carlos R.

Abstract

This article introduces complemental fuzzy sets, explains their semantics, and presents a subclass of this model that generalizes intuitionistic fuzzy sets in a novel manner. It also provides practical results that will facilitate their implementation in real situations. At the theoretical level, we define a family of $\mathfrak {c}$-complemental fuzzy sets from each fuzzy negation $\mathfrak {c}$. We argue that this construction provides semantic justification for all subfamilies of complemental fuzzy sets, which include $q$-rung orthopair fuzzy sets (when $\mathfrak {c}$ is a Yager's fuzzy complement) and the new family of Sugeno intuitionistic fuzzy sets (when $\mathfrak {c}$ belongs to the class of Sugeno's fuzzy complements). We study fundamental operations and a general methodology for the aggregation of complemental fuzzy sets. Then, we give some specific examples of aggregation operators to illustrate their applicability. On a more practical level, constructive proofs demonstrate that all orthopair fuzzy sets on finite sets that satisfy a mild restriction are Sugeno intuitionistic fuzzy sets, and they are $q$-rung orthopair fuzzy sets for some $q$ too. These contributions produce a new operational model that semantically justifies, and mathematically contains, “almost all” orthopair fuzzy sets on finite sets.
