A Novel Approach to Weighted Interval-Valued Intuitionistic Fuzzy Soft Multi Sets Based Decision Making

Abstract

Soft Set theory is one of the recent topics gaining signicance in nding rational and logical solutions to various real life problems which involve uncertainty, impreciseness and vagueness. In this article we have introduced the notions of reduct weighted intuitionistic fuzzy soft multi sets of weighted interval valued intuitionistic fuzzy soft multi set and propose an adjustable approach to weighted interval-valued intuitionistic fuzzy soft set based decision making by using reduct weighted intuitionistic fuzzy soft sets and level soft sets of reduct intuitionistic fuzzy soft sets. Some illustrative example is employed to show the feasibility of our approach in practical applications.
