In this paper, we prove Gr¨uss type inequality for setvalued functions. In this generalization, we investigate this inequality in three cases. At the first one, the pseudooperations are generalized and in the second case the addition operation ⊕ is idempotent and the multiplication operator ⊙ is generated. finally, in the third cases, both the operators are idempotent
