A generated fuzzy sigma-algebra equipped by Giles fuzzy connectives is
considered as a basis of this paper. Starting from a simple fuzzy mea
surable function, we introduce the notion of a fuzzy measurable functi
on. A one-to-one correspondence between the fuzzy measurable functions
and the random variables with values in the fuzzy real line is shown.
An inverse of a fuzzy measurable function is proved to be an extended
T(infinity)-fuzzy observable and vice versa. Linear operations on fuz
zy measurable functions are introduced.
