I will present a new method of including the complete NLO QCD corrections to hard
processes in the LO parton-shower Monte Carlo. This method, called
KrkNLO, requires the use of parton distribution functions in a dedicated
Monte Carlo (MC) factorization scheme which I will also discussed. In the
future, it may simplify introduction of the NNLO corrections to hard processes and the NLO
corrections to parton-shower Monte Carlo. Finally, I will show some numerical examples
of its practical implementation as well as comparisons with other calculations,
such as MCFM, MC@NLO, POWHEG and DYNNLO for single Z/γ *-boson production at the LHC.
