A commentary on “An improved score function for ranking neutrosophic
sets and its application to decision-making process”
Abstract
This work aims to study and observe all the existing score functions
that help to rank the single-valued neutrosophic set (SVNS) as well as
interval-valued neutrosophic set (IVNS) to make a better choice among
all the available alternatives in multi-criteria decision-making (MCDM)
problems. An intensive study about all these existing score functions
reveals that there holds some limitations in the method of ranking order
which is misleading the results in decision-making problems. These
observations about the existing score functions of the SVNS and IVNS
have been claimed with the help of well-defined examples, illustrating
an inefficiency of all these existing score functions. Thus, to propose
a valid score function for ranking SVNS and IVNS for making a better
selection among all the other available alternatives in MCDM problems is
still an open challenging research problem.
