On the structure and solutions of functional equations arising from queueing models

Analytic Root Clustering: A Complete Algorithm Using Soft Zero Tests [chapter]

Chee Yap, Michael Sagraloff, Vikram Sharma
2013 Lecture Notes in Computer Science  
A challenge to current theories of computing in the continua is the proper treatment of the zero test. Such tests are critical for extracting geometric information.  ...  We address the basic problem of determining the geometry of the roots of a complex analytic function.  ...  of Rouché's Theorem, we conclude f k (z) and f (m + z) have the same number of roots inside the ball D 0 (r).  ...

Application of Tauberian Theorem to the Exponential Decay of the Tail Probability of a Random Variable

Kenji Nakagawa
2007 IEEE Transactions on Information Theory  
For the proof of the theorem, we extend and apply so-called a finite form of Ikehara's complex Tauberian theorem by Graham-Vaaler.  ...  We present a theorem, according to which if the abscissa of convergence of the LS transform is negative finite and the real point on the axis of convergence is a pole of the LS transform, then the tail  ...  See [8] for the survey of the history and recent developments of Tauberian theory. The following is a well-known Tauberian theorem.  ...

Queueing systems with renovation

A. Ya. Kreinin
1997 Journal of Applied Mathematics and Stochastic Analysis  
Explicit solutions are discussed for the queues with Poisson input flow and for queues with general input and exponential service times.  ...  We study in this paper-single channel queueing systems with renovation. Such models are often encountered in computer science applications.  ...  By Rouche's theorem, the equation + .)z + 0 has only one root, z, E D. Therefore, the numerator of the fraction in (6) should be equal to 0 at z-z,.  ...

Analytic Computation Schemes for the Discrete-Time Bulk Service Queue

A. J. E. M. Janssen, J. S. H. van Leeuwaarden
2005 Queueing systems  
While in general this is true for the moments of the stationary queue length, for determining the distribution itself, dependence on the roots might cause some problems, in particular for tail probabilities  ...  Chaudhry & Kim [7] used the same technique and presented some numerical work. The technique of finding roots to complete a transform has become a classic one in queueing theory.  ...  Acknowledgement The authors like to thank Onno J. Boxma for his help in proving Theorem 4.1.

Models of Bus Queueing at Curbside Stops

Weihua Gu, Michael J. Cassidy, Yuwei Li
2015 Transportation Science  
A Markov chain embedded in the bus queueing process is used to develop steady-state queueing models for two special cases of this stop type.  ...  The models further show why the proxy measure that is used for the delay target in other bus-stop studies is a poor one.  ...  Acknowledgements Funding for this work was provided by the University of California Transportation Center, by the Volvo Research and Educational Foundations, and by the Dwight David Eisenhower Transportation  ...

An exact root-free method for the expected queue length for a class of discrete-time queueing systems

2019 Queueing systems  
For a class of discrete-time queueing systems, we present a new exact method of computing both the expectation and the distribution of the queue length.  ...  This allows us to derive a bound on the difference between the bulk-service and FCTL expected queue lengths, which turns out to be small in most of the realistic cases.  ...  Acknowledgements We would like to thank the anonymous reviewers and the associate editor for their valuable remarks and suggestions.  ...
