Generalised Interval-Valued Fuzzy Soft Set

الملخص EN

We introduce the concept of generalised interval-valued fuzzy soft set and its operations and study some of their properties.

We give applications of this theory in solving a decision making problem.

We also introduce a similarity measure of two generalised interval-valued fuzzy soft sets and discuss its application in a medical diagnosis problem: fuzzy set; soft set; fuzzy soft set; generalised fuzzy soft set; generalised interval-valued fuzzy soft set; interval-valued fuzzy set; interval-valued fuzzy soft set.
