  The strangeness enhancement signature of QGP formation at LHC energies is
carefully tackled in the present study. Based on HRG, the particle ratios of
mainly strange and multi-strange particles are studied at energies from lower
$\sqrt{s}\sim $ 0.001 up to 13 TeV. The strangeness enhancement clearly
appeared at more higher energies, and the ratios are confronted to the
available experimental data. The particle ratios are also studied using the
Cosmic Ray Monte Carlo (CRMC) interface model with its two different event
generators namely; EPOS $1.99$ and EPOSlhc which show a good agreement with the
model calculations at the whole range of the energy. We utilize to produce some
ratios. EPOS $1.99$ is used to estimate particle ratios at lower energies from
AGS up to the Relativistic Heavy Ion Collider (RHIC) while EPOSlhc is used at
LHC energies. The production of kaons and lambda particles is studied in terms
of the mean multiplicity in p-p collisions at energies ranging from 4 - 26 GeV.
We find that both HRG model and the used event generators, EPOS $1.99$ and
EPOSlhc, can describe the particle ratios very well. Additionally, the
freeze-out parameters are estimated for different collision systems, such as
p-p and Pb-Pb, at LHC energies using both models.
