M/M/1 retrial queue with collisions and working vacation interruption under N-policy

Li Tao, Zaiming Liu, Zhizhong Wang (2012)

RAIRO - Operations Research - Recherche Opérationnelle

Consider an M/M/1 retrial queue with collisions and working vacation interruption under N-policy. We use a quasi birth and death process to describe the considered system and derive a condition for the stability of the model. Using the matrix-analytic method, we obtain the stationary probability distribution and some performance measures. Furthermore, we prove the conditional stochastic decomposition for the queue length in the orbit. Finally, some numerical examples are presented.

Modèles Analytiques de Routeurs

Emmanuel Besson (2010)

RAIRO - Operations Research

We focus on performance study of routers in high-speed network through a queuing network analytical model. Such a model gives accurate results about classical performance criteria. For example, analytical study of packet loss probabilities in a router uses a product-form queuing network. The analytical results are compared to simulation results, and they provide routers managers with invaluable information for internal memories tuning.

Multiclass Hammersley–Aldous–Diaconis process and multiclass-customer queues

Pablo A. Ferrari, James B. Martin (2009)

Annales de l'I.H.P. Probabilités et statistiques

In the Hammersley–Aldous–Diaconis process, infinitely many particles sit in ℝ and at most one particle is allowed at each position. A particle at x, whose nearest neighbor to the right is at y, jumps at rate y−x to a position uniformly distributed in the interval (x, y). The basic coupling between trajectories with different initial configuration induces a process with different classes of particles. We show that the invariant measures for the two-class process can be obtained as follows. First,...

Non-stationary departure process in a batch-arrival queue with finite buffer capacity and threshold-type control mechanism

Wojciech M. Kempa, Dariusz Kurzyk (2022)

Kybernetika

Non-stationary behavior of departure process in a finite-buffer M X / G / 1 / K -type queueing model with batch arrivals, in which a threshold-type waking up N -policy is implemented, is studied. According to this policy, after each idle time a new busy period is being started with the N th message occurrence, where the threshold value N is fixed. Using the analytical approach based on the idea of an embedded Markov chain, integral equations, continuous total probability law, renewal theory and linear algebra, a...
