A Markov Renewal Approach to M/G/1 Type Queues with Countably Many Background States

Masakiyo Miyazawa
2004 Queueing systems  
Usually, matrix analysis is extensively used for studying the M/G/1 type queue. However, this may not be convenient when the background states are countable.  ...  Those results are applied to study the tail decay rates of the stationary distributions. This includes refinements of the existence results with extensions.  ...  In those papers, the stationary distribution of the conventional M/G/1 type queue is shown to be a Markov renewal function (also see Section 3.2).  ...

From Exhaustive Vacation Queues to Preemptive Priority Queues with General Interarrival Times

Dieter Fiems, Stijn De Vuyst
2018 International Journal of Applied Mathematics and Computer Science  
We consider the discrete-time G/GI/1 queueing system with multiple exhaustive vacations.  ...  By a transform approach, we obtain an expression for the probability generating function of the waiting time of customers in such a system.  ...  If not, the server leaves for another vacation of random duration; see, e.g., the works of Doshi (1986) , Takagi (1991) or Tian and Zhang (2006) for references to M/G/1-type vacation models.  ...

On a M/G/1 Queue Subject to Random Breakdowns with General Repair Times and Server's Choice for Deterministic or General Server Vacations

2019 Advances in Natural and Applied Sciences  
We study an M/G/1 Type queueing system subject to random failures.  ...  If the server chooses to take a vacation, he has the option of taking a deterministic vacation of constant duration or a general vacation of random length of time.  ...  Many meaningful and exciting results are derived cases 1 to 6. Hopefully, these new results will be an excellent addition to the literature of queueing theory.  ...

On the Time to Buffer Overflow in a Queueing Model with a General Independent Input Stream and Power-Saving Mechanism Based on Working Vacations

Martyna Kobielnik, Wojciech Kempa
2021 Sensors  
A single server GI/M/1 queue with a limited buffer and an energy-saving mechanism based on a single working vacation policy is analyzed.  ...  Packets that arrive while the buffer is saturated are rejected. The analysis is focused on the duration of the time period with no packet losses.  ...  A M/G/1-type queueing model with single working vacations and vacation interruption under a Bernoulli schedule was considered in [15] .  ...

We formulate the system as an embedded Markov chain at the departure epoch and by the M/G/1-type matrix analytic approach, we derive the probability generating function (PGF) of the stationary queue length  ...  This paper analyzes a discrete-time batch arrival queue with working vacations.  ...  Acknowledgements The authors would like to thank editors and three referees for their valuable comments and suggestions, which were very helpful to improve the paper.  ...

Stochatic Decomposition Result of an Unrelaible Queue with Two Types of Services

Gautam Choudhury, Akhil Goswami, Anjana Begum, Hemanta Kumar Sarmah
2020 Mathematics and Statistics  
Our intention is to look into some sort of united approach to establish stochastic decomposition result for two types of general heterogeneous service queues with generalized vacations for unreliable server  ...  of system (queue) size with no vacation and additional system (queue) size due to vacation.  ...  Infact, the notion of generalized vacation was first introduced by Fuhrmann and Cooper's for an M/G/1 type of model in order to generalize results of many existing vacation models of M/G/1 type.  ...

Characterizing the BMAP/MAP/1 Departure Process via the ETAQA Truncation

Qi Zhang, Armin Heindl, Evgenia Smirni
2005 Stochastic Models  
The departure process of a BMAP/MAP/1 queue is also given exactly by a MAP with an infinite number of states, which is obtained by filtration of the M/G/1-type process that models the BMAP/MAP/1 queue.  ...  Exploiting its full generality, one can apply the ETAQA methodology for the solution of M/G/1-type processes [16] to characterize the departure process of the BMAP/MAP/1 queue.  ...  M/G/1-type processes and ETAQA A BMAP/MAP/1 queue defines an M/G/1-type Markov process.  ...
