A Novel Decision Making Based on Interval Valued Intuitionistic Fuzzy Soft Set

摘要

Molodtsov first proposed the soft set theory, which can be used as a general mathematical tool for dealing with fuzzy and uncertain information. As a generalization of soft set, interval-valued intuitionistic fuzzy soft set is another soft set structure, it is a combination of an interval-valued intuitionistic fuzzy set and a soft set. The objective of this paper is to study the decision making based on intervalvalued intuitionistic fuzzy soft sets, the optimcal choice is needed to choose the best performance of the objects, in Zhang introduces the level soft sets, it can get the choice value of objects, in the present paper, we introduce the distance to evaluate the objects, the numberical example shows that the criteria is reasonable in objects selection on interval-valued intuitionistic fuzzy soft set.
