Query: Parton-Hadron duality in event generators   The validity of local parton-hadron duality within the framework of HERWIG
and JETSET event generators is investigated. We concentrate on ${\rm e}^{+}{\rm
e}^{-}$ annihilations in LEP 2 energy range as these interactions provide
theoretically the cleanest condition for the discussion of this concept.
