It is also an extension of intuitionistic fuzzy soft semigroup. Fuzzy subsets were initiated, and intuitionistic fuzzy soft semigroup was introduced as generalization of fuzzy soft set. On the other hand r-semigroup, and soft set were introduced. In 2011 Jiehua et al. [24] gave the notion of intuitionistic fuzzy soft semigroup. Muhammad Akram, et al.[l] in 2014 defined fuzzy soft r-semigroup. Our work is the extension of these last two structures. Moreover, the notion of intuitionistic fuzzy soft ideal over f -semigroup is also defined. We also investigate some related properties of the ideals.
