%X In the paper selected problems concerning microscale heat-transfer modeling are presented. In particular, the dual-phase-lag model (DPLM) containing two time lags, the relaxation and thermalization times, is considered. The aim of this research is to estimate the changes in the transient temperature field due to the perturbations of the DPLM thermophysical parameters (volumetric specific heat, thermal conductivity, and relaxation and thermalization times). To solve the problem methods of sensitivity analysis (direct approach) are applied. At the stage of numerical modeling, the axially symmetrical object subjected to an external heat flux is considered. Numerical computations are realized using the explicit scheme of finite difference method. In the final part of the paper the examples of computations are shown and the conclusions are formulated.
