In this paper, the concept of the infinitesimal realization factor is extended to the parameter-dependent performance functions in closed queueing networks. Then the concepts of a realization matrix (its element are called realization factors) and performance potential are introduced, and the relations between infinitesimal realization factors and these two quantities are discussed. This provides a united framework for both IPA and non-IPA approaches. Finally, another physical meaning of the service rate is given.
