Abstract
We proposed an aggregation operator which
is used to aggregate decision makers’ opinions in group
decision making process. First, a Choquet integral-based distance
between generalized interval-valued trapezoidal fuzzy
numbers is defined. Then combining the generalized intervalvalued
trapezoidal fuzzy number aggregation operator with
Choquet integral-based distance, an extension of technique
for order preference by similarity to ideal solution method is
developed to deal with a multi-criteria generalized intervalvalued
trapezoidal fuzzy number group decision making
problems, where inter-dependent or interactive characteristics
among criteria preference of decision makers are also
considered. Finally, an illustrative example is provided to
elaborate the proposed method.
