Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Application of fuzzy logic for data formalization in information systems YU.V. MININ, V.E. DIDRIKH, N.G. SHAKHOV, S.A. KOPYLOV To process and manage incomplete and inconsistent information in complex information systems, it is proposed to develop a fuzzy data model based on the use of paraconsistent intuitive fuzzy relationships, which are formed by generalizing fuzzy relationships using measures of faith and doubt. Developed operators on paraconsistent intuitive fuzzy relationships. It is noted that for any arbitrary paraconsistent intuitive fuzzy relations, first of all, the partitioning operation is used to transform them into highly noncontradictory paraconsistent intuitive fuzzy relations, and only then operations are used to convert the result into an arbitrary paraconsistent intuitive fuzzy relation. Keywords: information system, data model, fuzzy relations. DOI: 10.25791/pribor.04.2019.587 Contacts: E-mail: gromovtambov@yandex.ru Pp. 42-46.
