Abstract :
In this paper
based on the interval type-2 fuzzy sets, we introduce an extension
of fuzzy TOPSIS for handling fuzzy multiple attributes group
decision making problems. In the proposed method the fuzzy
positive ideal solution and fuzzy negative ideal solution are
obtained in the form of interval type-2 fuzzy sets without ranking
the elements of decision matrix, using the proposed method the
solution of decision problem is obtained with less computational
attempt
than existing methods.
