Soft set theory, initiated by Molodtsov, can be used as a new mathematical tool for dealing with imprecise, vague, and uncertain problems. In this paper, the concepts of two types of generalised interval‐valued fuzzy soft set are proposed and their basic properties are studied. The lattice structures of generalised interval‐valued fuzzy soft set are also discussed. Furthermore, an application of the new approach in decision making based on generalised interval‐valued fuzzy soft set is developed.
