Assessment of the Business Proposals Using Frank Aggregation Operators Based on Interval-Valued T-Spherical Fuzzy Information

An interval-valued T-spherical fuzzy set (IVTSFS) is an efficient framework to treat ambiguous and vague information more efficiently. It has four functions consisting of the in intervals. With help these functions, IVTSFS a reliable than other existing frameworks. This article aims establish algebraic operations IVTSFSs named Frank sum, multiplication, scalar multiplication stranded on t-norm t-conorm. Further, some averaging geometric aggregation operators (AOs), i.e., weighted (IVTSFFWA) (IVTSFFWG) are established based defined operations, then properties observed. The proposed approach supported by illustrative example, which we have applied our multiattribute group decision-making (MAGDM) problem. For significance approach, comparative study done. various effects variation parameters also investigated plays important role final results.
