IMPLEMENTATION AND SUPPORT FUZZY SYSTEMS BY MEANS THE RELATIONAL DATA MODEL

Abstract

This article was reviewed by the classical approach to the construction of relational relations, developed the relational model presentation and storage of fuzzy data, as well as the model of integration and fuzzy relations in relational database.For storage of data has been identified fuzzy specialized type of relationship. Driving this relationship satisfies the two conditions: corresponds to the requirements of the classical relational data model, and efficiently stores and presents a model of linguistic variable.Thus, the proposed terms of the expansion of basic operations of relational algebra class systems designed on the basis of fuzzy logic. Using the results obtained, it is possible to effectively use the advantages of database management systems on the basis of classical relational model for intelligent systems with elements of fuzzy logic. The use of this approach was the basis for the basic quantitative criteria for assessing the quality of higher education in the Kharkiv National University of Radio Electronics. The approach can be used as a component of self-assessment practices of higher education institutions for the comprehensive monitoring of the quality of higher education in the development of the concept of monitoring in Ukraine evaluation of higher education.
