Identification of the Most Significant Risk Factor of COVID-19 in Economy Using Cosine Similarity Measure under SVPNS-Environment

Abstract

In this article, we procure the idea of single-valued pentapartitioned neutrosophic cosine
similarity measure (SVPNCSM) and single-valued pentapartitioned neutrosophic weighted cosine
similarity measure (SVPNWCSM) under the single-valued pentapartitioned neutrosophic set
(SVPNS) environment. Besides, we formulate several interesting results on SVPNCSM and
SVPNWCSM of similarities between two SVPNSs. Further, we present a multi-attribute
decision-making (MADM) model under SVPNS environment using the SVPNCSM. Finally, we
provide a numerical example to show the applicability and effectiveness of our proposed MADM
technique.
