An extension of the Integrated Simple Weighted Sum Product (WISP) method is presented in this article, customized for application single-valued neutrosophic numbers. The suggested to take advantage that sets provides terms solving complex decision-making problems, as well problems associated with assessments, prediction uncertainty, imprecision, and so on. In addition, an adapted questionnaire ...

In this paper, we define a new cosine similarity between two interval valued neutrosophic sets based on Bhattacharya’s distance [19]. The notions of interval valued neutrosophic sets (IVNS, for short) will be used as vector representations in 3D-vector space. Based on the comparative analysis of the existing similarity measures for IVNS, we find that our proposed similarity measure is better an...

Abstract A single-valued neutrosophic multi-set is characterized by a sequence of truth membership degrees, indeterminacy degrees and falsity degrees. Nature allows us to consider multiple information in the truth, memberships which pretty useful multi-criteria group decision making. In this paper, we sequences intuitionistic fuzzy values instead numbers define concept fuzzy-valued multi-set. m...

The neutrosophic set (NS) is a more general platform which generalizes the concept of crisp, fuzzy, and intuitionistic fuzzy sets to describe the membership functions in terms of truth, indeterminacy, and false degree. Under this environment, the present paper proposes an improved score function for ranking the single as well as interval-valued NSs by incorporating the idea of hesitation degree...

In this work, we present definition of interval valued neutrosophic parameterized (IVNP-)soft set and its operations. Then we define parameter reduction method for IVNP-soft set.We also give an example which shows that they can be successfully applied to problem that contains indeterminacy.
