Our paper deals with the necessary properties in Fuzzy Measures. Therefore, it belongs to Fuzzy Mathematical Analysis. The Possibility Theory was created by Zadeh in a paper of 1978. As general purpose, to obtain a way to model flexible restrictions constructed from vague pieces of information. If we study the counterparts of expectations (from Probability Theory) in Possibility Theory, we obta...

In A Theory of Justice, John Rawls l defends two principles of justice by means of an appeal to a hypothetical "original position." However, these principles are strictly principles of justice by and for human beings, or at least by and for persons. Several philosophers have recently argued that tllis argument is flawed-is "speciesist"-in tllat there is no adequate justification for excluding a...

This paper addresses the issue of measuring similarity between pieces of uncertain information in the framework of possibility theory. In a first part, natural properties of such functions are proposed and a survey of the few existing measures is presented. Then, a new measure so-called Information Affinity is proposed to overcome the limits of the existing ones. The proposed function is based ...

In this paper, we formulate multiobjective fuzzy random bimatrix games, and introduce two kinds of equilibrium solution concepts. By applying possibility/necessity measure an expectation model to such the corresponding concepts are defined. To circumvent computational difficulties obtain solutions, algorithms based on bisection method is proposed, in which conditions membership function space r...
