An extended framework for autocratic multi-parameter group decision making using interval-valued intuitionistic fuzzy numbers

The objective of this paper is to develop a more generalized autocratic multi-parameter group decision-making (AMPGDM) model that provides an optimal solution for choosing an ideal object among several choices in AMPGDM circumstances. Then we apply interval-valued intuitionistic fuzzy numbers (IVIFNs) to form the weight of the parameters and entries of the decision matrices. Finally, we introduce two modified methods to deal with AMPGDM problems that will provide the same outcome but in a short amount of time.
