Neutrosophic Fuzzy Soft Matrix Theory and Its Application in Group Decision Making

Abstract

In 2020, Sujit et al. introduced the notion of the neutrosophic fuzzy set (NFS) to deal with uncertainty under a fuzzy environment where the fuzzy membership grade of every element of the field of the domain is associated with three independent neutrosophic components, namely truth, indeterminacy, and falsity membership grade. The main focus of the chapter is to introduce a neutrosophic fuzzy soft set (NFSS) to deal with uncertainty parametrically, and it gives the approximate solution to the problem. NFSS is a mixture of a neutrosophic set, fuzzy sets, and soft sets. So, it can be treated as a hybrid structure that gives more flexibility to solve multi-criteria decision-making problems under a fuzzy environment. NFSS evolved as an extension of fuzzy set, soft set, neutrosophic set, etc. Then the authors propose an algorithmic approach for group decision-making (GDM) problems using a neutrosophic fuzzy soft matrix (NFSM) and its related properties. Finally, an illustrative example shows the applicability of the proposed approach.

Life quality improvement of patients with non-small cell lung cancer undergoing targeted therapy: A case study of continuous care

“…The reason could be the fact that the continuous care model has the potential to mitigate negative symptoms such as fatigue and insomnia in patients, which, in turn, can enhance their emotional state and improve their overall life quality. [20][21][22] Specialized nurses can reduce patients negative emotions and improve their life quality by guiding them to complete simple and moderate aerobic exercise, as well as a healthy lifestyle, comfortable sleep environment, and correct concepts. This was consistent with the nursing research results of scholars on lung cancer patients.…”

Local feature matching and tracking optimization of machine VSLAM based on AG Sinkhorn

“…As the boost of deep learning (DL) technology in recent years, DL has gradually been applied in VSLAM 1–3 . Meanwhile, computer vision has high robustness, and can be used to handle visual problems in complex environments 4–6 . The Sinkhorn algorithm in view of the attention graph (AG) neural network is a new DL framework, which integrates Convolutional neural network, can classify and segment images through convolutional neural network, has strong generalization ability, and can handle large amounts of data.…”

“…[1][2][3] Meanwhile, computer vision has high robustness, and can be used to handle visual problems in complex environments. [4][5][6] The Sinkhorn algorithm in view of the attention graph (AG) neural network is a new DL framework, which integrates Convolutional neural network, can classify and segment images through convolutional neural network, has strong generalization ability, and can handle large amounts of data. Moreover, AG Sinkhorn does not require manual intervention when classifying and segmenting images, and the extracted feature points can be directly used for subsequent feature matching (FM).…”

An Autocratic Strategy for Multi-attribute Group Decision Making Based on Neutrosophic Triplets: A Case Study in Prioritizing Recreation Areas in the Tourist Industries

“…Taking advantage of neutrosophic sets, Farid et al (2022) introduced some novel aggregation operators for information fusion of SVNNs to handle multi-criteria group decision-making challenges. Debnath (2022) first introduced the notion of fuzzy quadripartitioned neutrosophic soft matrix (FQNSM) theory to generalize the FNSM concept and then developed a decision-making model based on FQNSMs. In order to initiate the complex single-valued neutrosophic (CSVN) setting and to determine its important algebraic laws, Mahmood and Ali (2022) elaborated the principle of CSVN PMM (CSVNPMM) operator and CSVN prioritized dual Muirhead mean (CSVNPDMM) operator.…”
