Abstract A system driven by correlated Gaussian noises related with disorder is investigated. The Fokker--Planck equation (FPE) for the system is derived. Using the FPE derived, some systems driven by correlated Gaussian noises related with disorder can be investigated for Brownian motors, nonequilibrium transition, resonant activation, stochastic resonance, and so on. We only give one example: i.e., using the FPE derived, we study the resonant activation for a single motor protein model with correlated noises related to disorder. Since the correlated noise related to disorder usually exists with the friction, for the
temperature, and so on, our results have generic physical meanings for
physics, chemistry, biology and other sciences.
