queueing: A Package For Analysis Of Queueing Networks and Models in R

Pedro,Cañadilla Jiménez, Yolanda,Román Montoya
2017 The R Journal  
queueing is a package that solves and provides the main performance measures for both basic Markovian queueing models and single and multiclass product-form queueing networks.  ...  The package solves Markovian models of the form M/M/c/K/M/FCFS, open and closed single class Jackson networks, open and closed multiclass networks and mixed networks.  ...  Finally, I thank everyone who has made contributions and suggestions or made use of the package.

Product Form Queueing Networks [chapter]

Simonetta Balsamo
2000 Lecture Notes in Computer Science  
Queueing network models have been extensively applied to represent and analyze resource sharing systems such as communication and computer systems and they have proved to be a powerful and versatile tool  ...  Various special models of product form queueing networks allow to represent particular system features such as state-dependent routing, negative customers, batch arrivals and departures and finite capacity  ...  Another research issue is the integration and/or the relation between queueing networks and other classes of models with different characteristics, such as for example stochastic Petri nets or stochastic  ...

Control of initialization bias in queueing simulations using queueing approximations

Manuel D. Rossetti, Patrick J. Delaney
1995 Proceedings of the 27th conference on Winter simulation - WSC '95  
The result of our methodology is a less biased and less variable estimator of the expected wait time in the queue.  ...  We used the ExtendTM simulation package for this research on a Macintosh Quadra 840AV.  ...  We should also continue our evaluation on more complex queueing systems such as networks of queues. We note that software packages already exist, e. g.  ...

Model predictive control for the acquisition queue and related queueing networks

Johan S. H. van Leeuwaarden, Erjen Lefeber, Yoni Nazarathy, Jacobus E. Rooda
2010 Proceedings of the 5th International Conference on Queueing Theory and Network Applications - QTNA '10  
Model Predictive Control (MPC) is a well established method in control theory and engineering practice. It is often the method of choice for systems that need to be controlled in view of constraints.  ...  We take a first exploratory step towards the application of MPC to queueing networks, highlighting the method and some open problems.  ...  Emphasis usually lies on the performance analysis of a model for a given service discipline and routing scheme.  ...

Optimal Routing in Closed Queueing Networks with State Dependent Queues

J. MacGregor Smith
2011 INFOR. Information systems and operational research  
Optimal routing in closed queueing networks with state dependent queues is the focus of this paper.  ...  Sometimes the networks will be purely state dependent M/G/c/c queues, while other times, there will be a mixture of M/M/c and M/G/c/c queues.  ...  To the best of our knowledge, no one has shown a Braess paradox for M/G/c/c state dependent networks within a closed network model, or even an open queueing network model.  ...

In this paper, we analyze the end-to-end delay performance of a tandem queueing system with mobile queues.  ...  Due to state-space explosion there is no hope for a numerical exact analysis for the joint-queue length distribution.  ...  Modeling this network as a tandem of queues, we performed an exact analysis for the joint queue length by extending the techniques developed in [6] and [9] .  ...
