Dombi Operators Based on Pentapartitioned Neutrosophic Pythagorean Sets for Online Education During the COVID-19 Pandemic

Abstract

In this chapter the authors have introduced the concept of score and accuracy function of the pentapartitioned neutrosophic pythagorean numbers (PNPN) and also defined ranking methods between two PNPNs which is based on its score function. Dombi operators are used in solving many multicriteria attribute group decision making (MAGDM) problems because of its very good flexibility with a general parameter. Here, Dombi T-norm and T-conorm operations of two PNPNs are defined. Based on this Dombi operations, the authors introduced two Dombi weighted aggregation operators PNPDWAA and PNPDWGA under pentapartitioned neutrosophic pythagorean environment and also studied its properties. Finally, the authors discussed about multicriteria attribute decision making method (MADM) using PNPDWAA or PNPDWGA operator and also an illustrative example is given for the proposed method which gives a detailed results to select the best alternative based upon the ranking orders.
