Sine Trigonometric Aggregation Operators with Single-Valued Neutrosophic Z-Numbers: Application in Business Site Selection

Business has a massive effect on both people and society as a whole in today’s culture. Businesses
make significant contributions to humanity’s general well-being and progress by promoting economic growth,
supporting innovation, producing wealth, and addressing social challenges. However, choosing the right location
for a business is a complex task, involving multiple criteria and qualitative and quantitative factors that heavily
rely on expert judgement. The researchers propose a unique approach called the SVNZN multi-attributed
decision-making method to aid decision-makers in this process. They introduce new operating laws for SVNZNs
based on the sine trigonometric (ST) function, known for its periodicity and symmetry over the origin, making
it favorable for decision-makers over multi-time phase parameters. Additionally, novel AOs such as SVNZN
weighted averaging and geometric operators are defined to combine SVNZNs effectively. Based on these AOs,
a decision-making technique for MADM problems is presented, and its applicability is demonstrated through
a numerical example of selecting the best location for a business. To validate and enhance the understanding
of these proposed techniques, the researchers conducted a comprehensive comparison analysis, including a
sensitivity analysis, considering existing literature on MADM difficulties. Figure 1 provides a thorough graphical
summary by visually representing all of the contributions and outcomes.
