Abstract:

This article presents two analytical models of a complex non-full-availability telecommunications systems and focuses on the properties of such systems. The authors conducted a series of tests aimed at checking the influence of particular parameters of the model on its accuracy. Inappropriate size and structure estimation of the external and internal structure of the system was tested. These studies made it possible the determination the conditions in which the application of the model is possible and how incorrect estimation of the size or structure of the system affects the model.
