Proceeding from the generalized master equation for the
reduced density operator of a dissipative N-level quantum system
driven by an external field, we arrived at exact averaging of
this equation in the case of random dichotomous driving. The
obtained kinetic equations are used to investigate the problem of the
dissipative transfer of a quantum particle in a molecular dimer with
dichotomically fluctuating intersite coupling. Furthermore, the
problem of relaxation in spin-boson system with dichotomically
modulated energy bias is considered. In the latter case, our
treatment generalizes the well-known result of the
non-interacting blip approximation.
