In this paper, an interval-valued Pythagorean triangular fuzzy number (IVPTFN) as a useful tool to handle decision-making problems with vague quantities is defined. Then, their operational laws are developed. By introducing a novel method of making a decision on the concept of possibility theory, a multi-attribute group decision-making (MAGDM) problem is considered, in which the attribute value...

In this paper, the notions of $(T,S)$-composition matrix and$(T,S)$-interval-valued intuitionistic fuzzy equivalence matrix areintroduced where $(T,S)$ is a dual pair of triangular module. Theyare the generalization of composition matrix and interval-valuedintuitionistic fuzzy equivalence matrix. Furthermore, theirproperties and characterizations are presented. Then a new methodbased on $tilde{...

Global warming is mainly caused by carbon emissions. Currently, fewer countries are concentrating on reducing The primary strategy utilized numerous to achieve emissions reduction the tax policy. With this in mind, a sustainable two-warehouse inventory model was taken into account for controllable rate investing green technology initiatives under uncertain emission and cost parameters. globe cu...

The success of any endeavor or process is heavily contingent on the ability to reconcile and satisfy balance requirements, which are often characterized by symmetry considerations. In practical applications, primary goal decision-making processes efficiently manage asymmetry that exists within different sources information. order address this challenge, aim study introduce novel Dombi operation...

For interval-valued fuzzy datasets, people have started to do research on interval-valued fuzzy rough sets and relevant models. However, these models could not be effectively applied to handle the real-valued datasets such as interval-valued fuzzy datasets as variable precision problems were not considered in interval-valued fuzzy rough sets. In this paper, fuzzy variable precision rough sets a...

In this article, the concept of parametric interval valued Pythagorean number (PIVPN) has been introduced, which is an extended version (PN). Here, a new score and accuracy function have innovated in PIVPN environment along with De-Pythagorean value concept. The tool techniques fruitfully applied to two realistic problems, namely networking critical path model (CPM) problem multicriteria group ...
