At α > 1, the condition for intuitionistic fuzzy generator does not hold.
At these conditions, it follows that μ(
x
) +
N
(μ(
x
)) > 1, which is not true.
For intuitionistic fuzzy generator, the condition of λ, α is changed.
For Yager-type intuitionistic fuzzy generator, the condition is
αα

Thus, with the help of the Sugeno-type intuitionistic fuzzy complement, IFS

Since the denominator, 1 + λ ⋅ μ
A
(
x
), in the non-membership term (1 − μ
A
(
x
))/
(1 + λ ⋅ μ
A
(
x
)) is greater than 1, the non-membership term is less than 1 − μ(
x
)
for all
x

X
.
Likewise, with Yager's intuitionistic fuzzy generator, IFS becomes
