This perturbative Quantum Chromo Dynamics (pQCD) analysis attempts to presenta simultaneous determination of parton distribution functions (PDFs) and thestrong coupling $\alpha_s(M^2_Z)$ from inclusion of inclusive H1 and ZEUS jet,DiJets and TriJets production cross sections data on the HERA I and II combineddata, as the central data sets for probing the internal structure of proton. Topresent an accurate pQCD analysis, we separate the role and influence ofinclusion jet production cross sections data from inclusion of the strongcoupling $\alpha_s(M^2_Z)$ as an extra fit parameter parameter on the gluondistribution. We show inclusion of jet, DiJets and TriJets production crosssections data improves the consistency between experiment and theory of crosssections for neutral current (NC) and charged current (CC) interactions of deepinelastic ${e^\pm}p$ scattering on proton up to $\sim 2.8$~\%. In addition, weshow inclusion of jet production cross section data and considering$\alpha_s(M^2_Z)$ as a pQCD free parameter not only reduce dramatically theuncertainty band of gluon distribution but also improve the consistency betweenexperiment and theory of NC and CC deep inelastic ${e^\pm}p$ scattering crosssections up to $\sim 3.6$~\%. Our simultaneous determination of PDFs and thestrong coupling $\alpha_s(M^2_Z)$ with inclusion of jet production crosssections data leads to $\alpha_s^{{\rm NLO}}(M^2_Z) = 0.12041 \pm 0.00086$,which is in a good agreement with world average and other individualmeasurements.
