In this study, a new decision-making
algorithm and method were given. We used PFS in the given method. PFS was
preferred because it is known that PFS gives clearer results than IFS. The
effect of music on cognitive development in early childhood was examined with
this decision-making method. In practice, the opinions of the experts about
cognitive development and the results of the method we proposed were compared. In
this study, the expectation score function was used. Weights and thus the
aggregated Pythagorean fuzzy decision value (APFDV) are calculated with the values obtained from
this function. The ranking is done with APFDV. Here, the values obtained from
expert opinions are determined as follows: Whichever expert has given more
opinion about the criteria, has been in the ranking before. Again, whichever
specialist has given fewer opinions remains behind the rankings. This is very
suitable for real-life events. The rankings obtained from the algorithm of the
study were the same as the rankings of the opinions of the experts.
