DESCRIPTION OF THE PROCESS OF INSTALLING ADEQUACY OF IMITATION MODELS BASED ON MASS SERVICE NETWORKS
This article is devoted to the substantiation of the application of queuing networks for simulation modeling as a heterarchic organizational structure of the system and hierarchical. It is shown that even with a very complex topology of the queuing network, it (the network) consists of phases, which are queuing systems with both queues and failures). Simulation models of the queuing system with single channel and two-channel (parallel connection) failures were developed and described, and based on the two-channel queuing system, an approach (by introducing the user function) to the managing distribution of the incoming flow between the serving channels was determined, models of queuing systems with parallel connection of any set of channels. Simulation experiments were performed and the results obtained were compared with the existing analytical calculations of steady-state probabilities of the physical states of queuing systems for the simplest incoming flow and exponentially distributed service intervals in the channels (obtained as a result of solving the Kolmogorov system) and their correspondence was established. On the basis of this fact, a conclusion has been made about the adequacy of both queuing systems and queuing networks.
