This paper shows a proposal for Type-reduction of an Interval Type-2 fuzzy set composed from α-cuts done over its primary membership functions. The definition of available Type-reduction methods for Interval Type-2 fuzzy sets are based on an homogeneous subdivision of the universe of discourse, so we propose an approximation algorithm for Type-reduction of an Interval type-2 fuzzy set through its...
Decision Making Support System based on Fuzzy Logic is considered in this paper for oncology disease diagnosis. The decision making procedure corresponds to the recognition (classification) of the new case by analyzing a set of instances (already solved cases) for which classes are known. Ontology (solved cases) is defined as Fuzzy Classification Rules that are formed by different Fuzzy Decision Trees...
This document describes using consensus methods to improve agent's knowledge in multiagent decision support systems. The problem of improving agent's knowledge, structure of decision, profile and criterions of consensus determining are presented in first part of article. Next a two stage algorithm of consensus determining was elaborated. This algorithm, among other things, allow to shorten the period...
This paper discusses a multi-agent based model of binary choice behavior with interdependence of decision-makers' choices. Analytical results established by other authors are briefly summarized where agent heterogeneity is not explicitly treated. Next the well-known Erdős-Rényi network class is considered to introduce agent heterogeneity via an explicit local interaction structure. Then the model...
