  The charged-particle multiplicity distribution and the transverse-energy
distribution measured in heavy-ion collisions at top RHIC and LHC energies are
described using the two-component model approach based on a convolution of the
Monte Carlo Glauber model with the Weibull model for particle production. The
model successfully describes the multiplicity and transverse-energy
distribution of minimum-bias collision data for a wide range of energies. The
Weibull-Glauber model can be used to determine the centrality classes in
heavy-ion collisions as an alternative to the conventional negative binomial
distribution (NBD)-Glauber approach.
