On the speed of convergence to stationarity of the Erlang loss system [PDF]
We consider the Erlang loss system, characterized by $N$ servers, Poisson arrivals and exponential service times, and allow the arrival rate to be a function of $N.$ We discuss representations and bounds for the rate of convergence to stationarity of the

A transient analysis to the M(τ)/M(τ)/k queue with time-dependent parameters
This work considers the infinite multi-server Markovian queueing model with balking and catastrophes where the rates of arrivals, service, balking, and catastrophes are time dependent. The catastrophes arrive as negative customers to the system.

Performance and sensitivity analysis of an M/G/1 queue with retrial customers due to server vacation
This paper treats an M/G/1 queue with retrial customers due to server vacation, which can be used to model a hospital service system. When an arriving customer finds the server on vacation at his arrival epoch, he either enters the retrial group with ...

Martingale approach to subexponential asymptotics for random walks [PDF]
Consider the random walk $S_n=\xi_1+...+\xi_n$ with independent and identically distributed increments and negative mean $\mathbf E\xi=-mx), x\to\infty$ for long-tailed distributions.

The number of overtakes in an M/M/2 queue
The phenomenon of overtaking in queueing systems and queueing networks has been addressed by several authors with various motivations in the last decades. Nevertheless, up to now, for the relatively simple M/M/2/FCFS queue, the distribution of the number

Functional analysis method for the M/G/1 queueing model with single working vacation
In this paper, we study the asymptotic property of underlying operator corresponding to the M/G/1 queueing model with single working vacation, where both service times in a regular busy period and in a working vacation period are function. We obtain that

The expected discrimination frequency for two-server queues
Fairness measures for queues were introduced for measuring the individual satisfaction of human customers with respect to the waiting experience. The measure which performs best in some sense is the expected discrimination frequency (DF).

In this investigation, single repairable server queueing system with bulk input and state dependent rates is analyzed by considering the general distributions for the repair, delay to repair and service processes.

Applications of Stochastic Semigroups to Queueing Models
Non-markovian queueing systems can be extended to piecewise-deterministic Markov processes by appending supplementary variables to the system. Then their analysis leads to an infinite system of partial differential equations with an infinite number of ...
