Mathematical Modeling in Heavy Traffic Queuing Systems

Sulaiman Sani, Onkabetse A. Daman
2014 American Journal of Operations Research  
In addition, the diffusion approximation can conveniently model performance characters such as the queue length or the waiting time distributions in these systems.  ...  Initially, we reviewed the onset of asymptotic modeling for heavy traffic single server queuing systems and then proceeded to multi server models supporting diffusion approximations developed recently.  ...  Acknowledgements The authors are grateful to Prof. Sivasamy, R., of the Statistics Department, University of Botswana for his suggestions, corrections and editing this article.  ...

The Finite-Skip Method for Multiserver Analysis [article]

Isaac Grosof, Mor Harchol-Balter, Alan Scheller-Wolf
2022 arXiv   pre-print
This class includes many important models, including the heterogeneous M/G/k, the limited processor sharing policy for the M/G/1, the threshold parallelism model, and the multiserver-job model under a  ...  Multiserver queueing systems are found at the core of a wide variety of practical systems.  ...  Previous work was only able to analyze simpler settings, such as the M/M/k and the M/(M+G)/2. In Fig. 2, we show a heterogeneous M/G/k with = 4 servers, where the server speeds vary by a factor of 4.  ...

Analysis of a discrete-time single-server queue with an occasional extra server

Herwig Bruneel, Sabine Wittevrongel
2017 Performance evaluation (Print)  
We consider a discrete-time queueing system having two distinct servers: one server, the "regular" server, is permanently available, while the second server, referred to as the "extra" server, is only  ...  For this queueing model, we are able to derive closed-form expressions for the steadystate probability generating functions (pgfs) and the expected values of the numbers of customers in the system at various  ...  Acknowledgement This research has been partly funded by the Interuniversity Attraction Poles Programme initiated by the Belgian Science Policy Office (BelSPO), Belgium.  ...

A reduced-peak equivalence for queues with a mixture of light-tailed and heavy-tailed input flows

Sem Borst, Bert Zwart
2003 Advances in Applied Probability  
The prefactor represents the probability that the heavy-tailed flows have sent at their peak rate for more than a certain amount of time, which may be interpreted as the 'time to overflow' for the light-tailed  ...  We determine the exact large-buffer asymptotics for a mixture of light-tailed and heavy-tailed input flows.  ...  The interplay of light-tailed and heavy-tailed large deviations is reminiscent of that for an M/G/2 queue with heterogeneous servers as described in [lOJ.  ...
