Fuzzy set valued interval soft sets

This thesis consists of seven sections. In section 1, a detailed literature review and the motivation of the thesis are presented. A few fundamental definitions and procedures for soft sets and fuzzy sets are introduced in Section 2. In Section 3, the definition of set- valued intervals is given and their operations are presented. In Section 4, the definition and operations of set-valued interval soft sets in light of the literature review are explained. In Section 5, the concept of fuzzy set-valued intervals is described, and their operations are explained with examples. In Section 6, fuzzy set-valued interval soft sets are discussed, along with their operations, and the properties of the operations are further investigated with examples. In Section 7, information about the thesis's overall framework is provided and the thesis's findings are discussed.
