  The concept of new methodology of adding QCD NLO corrections in the initial
state Monte Carlo parton shower (hard process part) is tested numerically
using, as an example, the process of the heavy boson production at
hadron--hadron colliders such as LHC. In spite of the use of a simplified model
of the process, all presented numerical results prove convincingly that the
basic concept of the new methodology works correctly in practice, that is in
the numerical environment of the Monte Carlo parton shower event generator. The
differences with the other well established methods, like MC@NLO and POWHEG,
are briefly discussed and future refinements of the implementation of the new
method are also outlined.
