The evaporation residue (ER) cross sections for producing superheavy nuclei with charge number 118 in some ${}^{48}$Ca-induced reactions are studied theoretically with the dinuclear system model with dynamical potential energy surface (DNS-DyPES model) for the experiment, which is aimed to produce the isotopes of element $Z=118$. The experiment is under way at the Flerov Laboratory of the Joint Institute for Nuclear Research in Dubna, Russia. The calculated ER cross sections for ${}^{48}$Ca + ${}^{249}$Cf are found to be in good agreement with the experimental results. The excitation functions for ${}^{48}$Ca + ${}^{250,251,252}$Cf are calculated and predicted, and the dependence of the residue cross sections for producing ${}^{293,294,295,296,297}$118 on the bombarding energies is also calculated for an isotopic composition of the Cf target. The possibilities for producing element 118 with other projectile-target combinations such as ${}^{50}$Ti + ${}^{248}$Cm and ${}^{54}$Cr + ${}^{244}$Pu at different mass asymmetries of entrance channels are also investigated.
