  The paper is devoted to the description and prediction of various bulk
observables in the Pb+Pb collisions at the LHC energy $\sqrt{s_{NN}}=5.02$ TeV
within the integrated hydrokinetic model (iHKM). Sensitivity of the results to
the choice of the appropriate model parameter values is also investigated. It
is found that changing of the relaxation time and the rate of thermalization,
which characterize the pre-thermal stage of the matter evolution, as well as
switching to another equation of state at the hydrodynamic stage and the
corresponding hadronization temperature, does not destroy the results, if
simultaneously one provides an appropriate adjusting of the initial time for
the superdense matter formation and related maximal initial energy density.
