  A comparative study of $V^0$ ratios has been performed between HIJING, Sibyll
and QGSJET model-based event generators in this paper. The ratios under study
are {\alam}/{\lam}, {\alam}/{\ks} and {\xim}/{\lam} as a function of rapidity
$y$, rapidity loss ($\Delta y$) and {\ppt} from $pp$ collisions at \sqrts~=
0.2, 0.9, and 7 TeV and these simulations are then compared with the STAR and
LHCb fiducial phase spaces in different {\ppt} regions. Although the models
could produce some of the ratios in a limited {\ppt} and/or $y$ region, none of
them completely predicts the experimental results. The QGSJET has good
predictions with the data in most of the cases but since the model does not
include the $\Xi$ particle definition, therefore it does not give any
predictions for $\Xi$/{\lam} ratios. The extrapolation to the highest possible
energies can be studied by re-tune some of the basic parameters based on
current and previous measurements. These kinds of systematic comparison studies
are also useful to apply certain constraints on the pQCD and non-pQCD-based
hadronic event generators to significantly improve the predictions of Standard
Model physics at the RHIC and LHC experimental data for the understanding of
underlying physics mechanisms in high energy collisions.
