The problems which today's institutions and businesses are currently facing have some characteristics which make them different from those that have been studied and treated by means of those models which have traditionally been used. The continuous changes being produced in social, financial and management systems have meant that the…

Models based of several configurations of discrete-time recurrent neuro-fuzzy systems, previously introduced in [1], [2], [3], [4], are analysed and interpreted. The complexity of such systems allows modelling of human-related processes, or creativity processes. Issues related to modelling chaotic processes are focused.

The concepts of measurement and information are central to the accountancy model of the representation of business (Mattesich, 1964; Ijiri, 1967 & 1975; Sterling, 1970). The classical financial accounting remains based on elementary arithmetic (groups of differences constructed on the commutative and cancelling monoid of the real positives supplied by…

In this paper we introduce some models and Systems we developed in the field of group decision support in fuzzy environments. The basic framework within which we operate is the following ore. We have a set of individuals who present their opinions concerning an issue in question, and a moderator,…

The aim of this essay is to propose an alternative study of the model of decision-making in conditions of uncertainty. The proposition covers: a) a fuzzy treatment of the "state of events", b) an algorithm to obtain the "consequences" of each "course of action", c) a "methodology" with respect to…
