In the article, we study associated production of heavy quarkonia and $D$ mesons in the improved color evaporation model using the high-energy factorization as it is formulated in the parton Reggeization approach. The last one is based on the modified Kimber-Martin-Ryskin-Watt model for unintegrated parton distribution functions and the effective field theory of Reggezied gluons and quarks, suggested by L.N. Lipatov. We predict cross section for associated $J/\psi$ or $\Upsilon$ and $D$ hadroproduction via the single and double parton scattering mechanisms using the set of model parameters that have been obtained early for the description of single and double $J/\psi$ and $\Upsilon$ production at the LHC energies. The numerical calculations are realized using the Monte-Carlo event generator KaTie. The calculation results are compared with the LHC data at the energies $\sqrt{s} = 7 \mbox{ and } 8$ TeV.
