On Generalised Interval-Valued Fuzzy Soft Sets

Abstract EN

Soft set theory, initiated by Molodtsov, can be used as a new mathematical tool fordealing with imprecise, vague, and uncertain problems.

In this paper, the concepts of two types ofgeneralised interval-valued fuzzy soft set are proposed and their basic properties are studied.

Thelattice structures of generalised interval-valued fuzzy soft set are also discussed.

Furthermore, anapplication of the new approach in decision making based on generalised interval-valued fuzzysoft set is developed.
