&lt;p&gt;The concept of being uniform strong interval-valued intuitionistic fuzzy (also termed as USIVIF) is an integration two ideologies, which are called "uniformity" and "strong sets". Inspired by the study on topological indices, it natural to introduce IVIFTIs. Originally, indices were generalized for sets However, utilization provides a finer approach, especially if there multiple uncertainties based intervals. Consequently, both theories imply that not fixed depend certain situations...
