t -spherical fuzzy soft sets and its aggregation operators with application in decision-making

In the present manuscript, we introduce a novel concept of t-spherical fuzzy soft set with various important operations and properties. in the field of information theory, an aggregation operator is a structured mathematical function which aggregates all the information received as input and provides a single output entity, which are found to be applicable for various important decision making applications. some averaging aggregation operators and geometric aggregation operators (weighted, ordered and hybrid) for t-spherical fuzzy soft numbers have been proposed with their various properties. further, utilizing the proposed aggregation operators of various types along with the properly defined score function/accuracy function, an algorithm for solving a decision making problem has been provided. the proposed methodology has also been well illustrated with the help of a numerical example. some comparative remarks and advantages of the introduced notion of t-spherical fuzzy soft set and the proposed methodology have been listed for a better motivation and readability.
