A comparative study of $V^0$ ratios has been performed between HIJING, Sibylland QGSJET model-based event generators in this paper. The ratios under studyare {\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 andLHCb fiducial phase spaces in different {\ppt} regions. Although the modelscould produce some of the ratios in a limited {\ppt} and/or $y$ region, none ofthem completely predicts the experimental results. The QGSJET has goodpredictions with the data in most of the cases but since the model does notinclude the $\Xi$ particle definition, therefore it does not give anypredictions for $\Xi$/{\lam} ratios. The extrapolation to the highest possibleenergies can be studied by re-tune some of the basic parameters based oncurrent and previous measurements. These kinds of systematic comparison studiesare also useful to apply certain constraints on the pQCD and non-pQCD-basedhadronic event generators to significantly improve the predictions of StandardModel physics at the RHIC and LHC experimental data for the understanding ofunderlying physics mechanisms in high energy collisions.
