On the use of iterative approximations in queueing networks, with simple applications

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review


Networks of queues which have a productform solution can be analyzed easily by the convolution method or with mean value analysis. Regrettably, however, many practical queueing network models do not possess a productform solution. In this paper the following approach is advocated for models with slight deviations from the productform conditions: approximate the model interatively by a sequence of models which satisfy conditions for simple analysis.

Quite often aggregation and mean value analysis provide the natural approach for designing an iteration step.

Applications which are mentioned are: two-phase servers where the first phase is a preparatory one; a type of priorities; blocking; many-chains networks; FCFS-servers with different workloads for different types of customers.
