N2 - A new version of the projection operator is proposed that allows its application area to be extended, including a general treatment of nonequilibrium subsystems. The modified operator form is used as a means of separating the subsystem variables. The given approach furnishes a simple recipe for the derivation of the dynamic equations and the closed master equation. An example of the operator application to the quantum laser theory is considered.
