Industrial Automatic Control Systems and Controllers Annotation << Back Fuzzy Approach to Data Modeling in Information Systems V.E. Didrikh, M.A. Ivanovsky, O.G. Ivanova, S.V. Danilkin Existing approaches to the development of fuzzy data models used in the synthesis of information systems are considered. An approach to the construction of a fuzzy data model based on the use of the theory of a paraconsistent, intuitive fuzzy set is proposed. Operators are defined by fuzzy relationships that extend standard operators, such as selection, union, connection, projection. The proposed fuzzy data model is capable of managing incomplete and inconsistent information in information systems. Keywords: information system; relational data model; fuzzy data model; fuzzy relations. DOI: 10.25791/asu.04.2019.579 Contacts: - Pp. 45-48.
