We Consider the problem of a system coupled to an ensemble of independent harmonic oscillators acting as a reservoir. We use an extension of the functional derivative technique to analyze some of the effects of adding stochastic terms to the system-reservoir coupling parameters. Two approaches (quantum master equation and Langevin equation) are considered and their ranges of validity and differences are examined.
