  Quark-hadron phase transition is simulated by an event generator that
incorporates the dynamical properties of contraction due to QCD confinement
forces and randomization due to the thermal behavior of a large quark system on
the edge of hadronization. Fluctuations of emitted pions in the $(\eta,\phi)$
space are analyzed using normalized factorial moments in a wide range of bin
sizes. The scaling index $\nu$ is found to be very close to the predicted value
in the Ginzburg-Landau formalism. The erraticity indices $\mu_q$ are determined
in a number of ways that lead to the same consistent values. They are compared
to the values from the Ising model, showing significant difference in a
transparent plot. Experimental determination of $\nu$ and $\mu_q$ at the LHC
are now needed to check the reality of the theoretical study and to provide
guidance for improving the model description of quark-hadron phase transition.
