Fuzzy set theory, rough set theory, and soft set theory are three effective mathematical tools for dealing with uncertainties and have\r\nmany wide applications both in theory and practise.Meng et al. (2011) introduced the notion of soft fuzzy rough sets by combining\r\nfuzzy sets, rough sets, and soft sets all together. The aim of this paper is to study the parameter reduction of fuzzy soft sets based\r\non soft fuzzy rough approximation operators. We propose some concepts and conditions for two fuzzy soft sets to generate the\r\nsame lower soft fuzzy rough approximation operators and the same upper soft fuzzy rough approximation operators. The concept\r\nof reduct of a fuzzy soft set is introduced and the procedure to find a reduct for a fuzzy soft set is given. Furthermore, the concept\r\nof exclusion of a fuzzy soft set is introduced and the procedure to find an exclusion for a fuzzy soft set is given.
