Abstract
In this thesis. First, we present the concept of (crisp) fuzzy sets and their operations. Second, we introuduce the notion of intuitionistic fuzzy sets and lattice L-fuzzy sets.Moreover, we study the theory of soft sets. Finally, we define a fuzzy soft set theory and its related properties. We then define fuzzy soft aggregation operators that allows constructing more efficient decision making method.
