Abstract: Uncertainty measures of fuzzy soft sets are studied. The axioms for inclusion measure and similarity measure are proposed. Based on fuzzy implication operators, a new category of inclusion measures and similarity measures are presented. This approach is general in the sense that by using different fuzzy implication operators one can get different uncertainty measures. The basic properties of these uncertainty measures are examined. It constructs a decision method which is applied to a financial diagnosis problem that is based on similarity measures.

Key words: soft set, fuzzy soft set, similarity measure, inclusion measure
