Comparative study of throughput of queueing networks with exponential and deterministic serving time in nodes

Research output: Contribution to journalArticle


Queueing network consist ·|M|m- and ·|GI|∞- systems is considered. The input flow of claims for open network is the simplest (Poisson flow). It is proved that if in several ·|M|1- systems service time changes from exponential to deterministic with the same average value, so productivity characteristics of network are not reduced. In particular, for open network summary number of claims in modified network is stochastically less then in initial network. For closed network average loading coefficients of systems in modified network exceed those of initial network.
