Diffusivity and mobility are characteristic quantities of transport phenomena easily correlated to the transition rates and the biasing force in regular systems. In the absence of regularity any quantification in terms of a rate is obscured by the disorder induced distribution of rates or waiting times. It is this characteristic property of random media together with the stochastic and often hierarchical nature of relaxational processes which prevents a straightforward analytical approach to rate controlled quantities in these systems. If a model for the underlying microscopic individual transition is at hand computer simulations yield a powerful tool for quantitatively accessing a wide spectrum of observables.
