Optimal Pricing Analysis of Computer Networks Based on a Queueing System With Retrial Mechanism
We consider a single-server retrial queue with a Poisson arrival process and exponential service times, where the server is unreliable. Assume there is no waiting space in front of the server and the customer who finds the server unavailable joins an ...

This paper explores the two-commodity (TC) inventory system in which commodities are classified as major and complementary items. The system allows a customer who has purchased a free product to conduct Bernoulli trials at will.

Bounds and Maxima for the Workload in a Multiclass Orbit Queue
In this research, a single-server M-class retrial queueing system (orbit queue) with constant retrial rates and Poisson inputs is considered. The main purpose is to construct the upper and lower bounds of the stationary workload in this system expressed ...

Waiting Time Distribution and Some Characteristics in Finite Queueing Systems with Retrials [PDF]
A retrial queueing system consists of a primary service facility of finite capacity and an orbit. Customers arrive from outside the system according to Poisson process, or from the orbit according to a rate that depends upon the number of customers in ...

Optimization of multi-channel queuing systems with a single retail attempt: Economic approach [PDF]
This paper deals with retrial queues of the |MQ/M/c/∞|- type in which the rate of input flow depends on the number of sources of repeated calls and each call has only one retrial attempt.

A literature review on retrial queueing system with Bernoulli vacation [PDF]
The retrial phenomenon occurs inherently in a wide range of queueing systems. The majority of retrial queueing models do not account for vacation. However, in practice, retrial queueing systems undergo vacations for maintenance or other reasons.

On a batch arrival queuing system equipped with a stand-by server during vacation periods or the repairs times of the main server [PDF]
We study a queuing system which is equipped with a stand-by server in addition to the main server. The stand-by server provides service to customers only during the period of absence of the main server when either the main server is on a vacation or it ...

Retrial Queuing-Inventory Systems with Delayed Feedback and Instantaneous Damaging of Items
This paper studies a Markov model of a queuing-inventory system with primary, retrial, and feedback customers. Primary customers form a Poisson flow, and if an inventory level is positive upon their arrival, they instantly receive the items.

Retrial Queues with Unreliable Servers and Delayed Feedback
In this paper, models of unreliable multi-server retrial queues with delayed feedback are examined. The Bernoulli retrial is allowed upon the arrival of both primary (from outside) and feedback customers (from orbit), as well as the Bernoulli feedback ...
