Interval-Valued Vague Soft Sets and Its Application
Molodtsov has introduced the concept of soft sets and the application of soft sets in decision making and medical diagnosis problems. The basic properties of vague soft sets are presented. In this paper, we introduce the concept of interval-valued vague soft sets which are an extension of the soft set and its operations such as equality, subset, intersection, union, AND operation, OR operation,...
متن کاملMulti-aspect Fuzzy Soft Sets and their Properties
In this paper, the concept of multi-aspect fuzzy soft sets is proposed. This concept is an extension of the ordinary concept of fuzzy soft sets. Basic operations like union, intersection and complement are presented, and some important properties are studied. Numerical examples are used to further elucidate some of the operations and properties.
متن کاملIdealistic Vague Soft Rings and Vague Soft Ring Homomorphism
Soft set theory, proposed by Molodtsov has been regarded as an effective mathematical tool to deal with uncertainties. Vague set is a set of objects, each of which has a grade of membership whose value is a continuous subinterval of [0, 1]. Such a set is characterized by a truth-membership function and a falsemembership function. Thus, a vague set is actually a form of fuzzy set, albeit a more ...
متن کاملFuzzy GML Modeling Based on Vague Soft Sets
The Open Geospatial Consortium (OGC) Geography Markup Language (GML) explicitly represents geographical spatial knowledge in text mode. All kinds of fuzzy problems will inevitably be encountered in spatial knowledge expression. Especially for those expressions in text mode, this fuzziness will be broader. Describing and representing fuzziness in GML seems necessary. Three kinds of fuzziness in ...
متن کاملImplementation of Vague-Fuzzification using Vague Sets
A mathematical procedure used to convert an element in the universe of discourse into the membership value of the fuzzy set is termed as fuzzification. In this paper we propose a new technique Vague-Fuzzification to implement fuzzification using vague sets. The proposed technique is designed that is using two methods to implement the same. First method includes a positive ordered transforming f...
