This article brings together some ideas on fuzzy intelligent systems. We start from fuzzy controllers, and we reflect on the role of fuzzy logic in other domains in which, in spite of optimistic forecasts, advances made are still less significant. By way of example, we make mention of certain fields in which it is foreseeable that there will be significant advances made using fuzzy logic. Finally, we emphasise certain problems and proposals that we consider to be of interest.
In this paper the execution of Fuzzy Knowledge Bases in the truth space is briefly analyzed. The computational efficiency of the process is significantly increased by means of a parameterized description based on the linguistic truth values described by Baldwin. This permits executing the Fuzzy Knowledge Base through operations involving only simple numerical values, thus avoiding the direct analytic manipulation of possibility distributions. A Petri Net-based formalism that permits representing...
This paper describes a classification for fuzzy quantifiers that makes it possible to include a significant number of cases of interest (exception, comparatives). All quantifiers therein described can be evaluated by following a fuzzy model with probabilistic interpretation, based on the Theory of Generalized Quantifiers.
This paper deals with the formal description of what we call Fuzzy Temporal Propositions: propositions with explicitly expressed information of a temporal type. The set of syntactic rules that make a grammar up for defining a language for this kind of propositions is presented. For some of the rules, examples that illustrate the expressive power of this type of knowledge representation are introduced. Semantic criteria and definitions are also introduced through examples in order to show how intuitive...
