Abstract

The results of perturbation analysis pertaining to closed queuing networks are reviewed, showing that the basic principles of perturbation analysis can be explained using a dynamic point of view. It is shown that perturbation generation and perturbation propagation rules can be viewed as counterparts of the linearization theory of nonlinear continuous variable dynamic systems; the concept of perturbation realization describes the steady-state effect of a perturbation and reflects the special dynamic feature of a closed queuing network. The realization probability can be used to calculate the sensitivity of steady-state throughputs and some other sensitivities
