To a fuzzy choice function C we assign the indicators of revealed preference WAFRP(C), SAFRP(C) and the indicators of congruence WFCA(C), SFCA(C). These indicators measure the deg...
This paper deals with a model of decision– making in two stages. In the first stage from a set of expertises one chooses the most rational ones, while in the second stage one o...
The aim of this work is to study an essential property in the framework of fuzzy preference structures, which is the transitivity. In particular, we discuss the relationship betwe...
Abstract – In this paper two new concepts are introduced: the similarity and the (∗,δ)-equality of fuzzy choice functions. We investigate the manner the similarity and (∗,δ...
It is shown that preferences can be constructed from observed choice behavior in a way that is robust to indifferent selection (i.e., the agent is indifferent between two alternat...
