  The states of three-qubit systems split into two inequivalent types of
genuine tripartite entanglement, namely the Greenberger-Horne-Zeilinger (GHZ)
type and the $W$ type. A state belonging to one of these classes can be
stochastically transformed only into a state within the same class by local
operations and classical communications. We provide local quantum operations,
consisting of the most general two-outcome measurement operators, for the
deterministic transformations of three-qubit pure states in which the initial
and the target states are in the same class. We explore these transformations,
originally having standard GHZ and standard $W$ states, under the local
measurement operations carried out by a single party and $p$ ($p=2,3$) parties
(successively). We find a notable result that the standard GHZ state cannot be
deterministically transformed to a GHZ-type state in which all its bipartite
entanglements are nonzero, i.e., a transformation can be achieved with unit
probability when the target state has at least one vanishing bipartite
concurrence.
