A time-dependent variational principle is given for nonequilibrium density matrixof a quantum system. It allows a derivation of dynamical equations for thermodynamical forces which are the Lagrangian parameters of the present theory. Ifthe system is near equilibrium, these equations determine the transport coefficientswhich satisfy the reciprocity relations. For the understanding of irreversibility, theintroduction of the van Hove parameter turns out to be essential, which bases upon adistinct separation of microscopic and macroscopic scales in time.
