On Generalised Interval-Valued Fuzzy Soft Sets

[摘要] 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.
