Fuzzy soft multiset theory
Summary: In 1999, Molodtsov introduced the concept of soft set theory as a general mathematical tool for dealing with uncertainty. In [Appl. Math. Sci., Ruse 5, No. 69--72, 3561--3573 (2011; Zbl 1257.03081)] the first author et al. introduced the definition of soft multiset as a generalization of Molodtsov's soft set. In this paper we give the definition of fuzzy soft multisets as a combination of soft multisets and fuzzy sets, and study their properties and operations. We give examples for these concepts. Basic properties of these operations are also given. An application of this theory in decision-making problems is shown.
