On the basis of Langevin equation the optimal SUSY field scheme is formulated
to discribe a non-equilibrium thermodynamic system with quenched disorder and
non-ergodicity effects. Thermodynamic and isothermal susceptibilities, memory
parameter and irreversible response are determined at different temperatures
and quenched disorder intensities.Comment: 35 pages, 6 figs, 2 diagrams, submitted to Physica
