Fuzzy Implication Revisited: a New Type of Fuzzy Implication Explains
1. Formulation of the problem 1:1: It is necessary to represent implication in expert systems Our knowledge of complex systems is often incomplete, and therefore, we have to rely on the expert's statements, These statements are usually formulated not in mathematical terms, but in words of natural languages. Fuzzy logic is a methodology for formalizing such statements. Since a large part of expe...
متن کاملFuzzy Inclusion Dependencies in Fuzzy Databases
Crisp databases and fuzzy databases are developed to provide users with the ability to store data that can be used in deriving information satisfying their needs. The design of these databases requires several theoretical foundations, efficiency, and ease of use. Thus, they accommodate a wider range of real-world requirements and provide a friendlier environment for man-machine interaction. The...
متن کاملFuzzy Join Dependency in Fuzzy Relational Databases
The join dependency provides the basis for obtaining lossless join decomposition in a classical relational schema. The existence of Join dependency shows that that the tables always represent the correct data after being joined. Since the classical relational databases cannot handle imprecise data, they were extended to fuzzy relational databases so that uncertain, ambiguous, imprecise and part...
متن کاملOn Fuzzy Implication Relations
For the last decade, fuzzy controllers have been applied with great success to a variety of domains. Nevertheless the underlying theoretical framework still remains unsatisfactory. One of the key questions still open is concerned with approximate reasoning. How should we determine the eeect of applying the fuzzy rule IF x is ~ A THEN y is ~ B] to ~ A 0 with ~ A 0 , ~ A, and ~ B being fuzzy sets...
متن کاملLattice on Fuzzy Implication
In this paper we present some Boolean algebras in the form of lattice by using the fuzzy implication. We show that these methods lead to various and much richer algebraic structures on the set of all fuzzy implications than obtained in the literature. KeywordsFuzzy logic connectives, Fuzzy implication, Algebras, Lattice.
