Topological Structure of Single-Valued Neutrosophic Hesitant Fuzzy Sets and Data Analysis for Uncertain Supply Chains

Abstract

From production to retail, the food supply chain (FSC) encompasses all stages of food production. Food is now transmitted across continents over long ranges. People depend on supply chains for basic necessities such as food, water, drinks, etc. Any disruption in these shipment pipelines poses a serious threat to human life. Supplier selection (SS) has been identified as a crucial component of FSC, which has been contemplated as a multi-criteria decision-making (MCDM) problem in many studies. The failure of some specific MCDM problems is due to failure in contemplating the relationships between alternatives under uncertain circumstances. To address such challenges, we present a contemporary method for designating green suppliers based on single-valued neutrosophic hesitant fuzzy (SVNHF) information, in which the input assessment is taken into account using single-valued neutrosophic hesitant fuzzy numbers (SVNHFNs). The foremost purpose of this analysis is to construct a topological structure on single-valued neutrosophic hesitant fuzzy sets (SVNHFSs) as well as to validate several key properties with examples. We discuss certain properties of SVNHF topology such as the SVNHF closure, SVNHF interior, SVNHF exterior, and SVNHF frontier. We also examine the conceptualization of the SVNHF dense set and SVNHF base in SVNHF topology using comprehensive examples. Eventually, to demonstrate and validate the superiority and inferiority ranking (SIR) method and choice value (CV) method in terms of their rationality and scientific basis, a real-world example of supplier selection in a food supply chain is provided. A comparative analysis is also performed to discuss the symmetry, validity and advantage of the proposed techniques.

Fermatean Neutrosophic Topological Spaces and an Application of Neutrosophic Kano Method

“…Studies such as [4][5][6][7][8], in which solutions to fuzzy-based decision making problems are sought and very important findings related to daily life are obtained, can be designed to include uncertainty and indecision situations by using neutrosophic set theory. The studies given in [11][12][13][14][15][16], where contradictory and incomplete data on neutrosophic decision-making processes based on uncertainty and instability modeling can be explained in a sense and where important studies have been made from different perspectives, can be evaluated by including a topological context and Fermatean structure in these studies. When [21][22][23][24] are examined, very important ideas may emerge for studies in which studies that synthesize the Kano model and multi-criteria decision-making can be applied.…”

“…Especially, studies dealing with dependent and independent variables in an unusual way make a great contribution to the related fields. NS is a strong model that brings a new perspective to strategic development, decision-making and analysis in many areas of daily life, and substantial studies have emerged in many fields [10][11][12][13][14][15][16][17].…”

Cubic Intuitionistic Fuzzy Topology with Application to Uncertain Supply Chain Management

“…Bairagi [59] developed a novel MCDM model for warehouse location selection in supply chain management. Recently, some applications of fuzzy modeling have been developed, such as uncertain supply chains [60], medical tourism supply chains [61], sustainable plastic recycling processes [62], and pattern recognition [63].…”
