an effective fuzzy aggregation method is required. Any
fuzzy aggregation method always needs to contain a defuzzification
method due to the results of human judgments with fuzzy linguistic
variables are based on TFNs. The defuzzification refers to the
selection of a specific crisp element based on the output fuzzy set,
which convert fuzzy numbers into crisp may score. This study is
applying the converting fuzzy data into crisp scores developed by
[44], the main procedure of determining the left and right scores
by fuzzy minimum and maximum, the total score is determined as
a weighted average according to the membership functions.
