Characterization of the departure process from an queue

Jayesh Kumaran, Kenneth Mitchell, Appie van de Liefvoort (2010)

RAIRO - Operations Research

Similarity:

In this paper we propose a family of finite approximations for the departure process of an queue indexed by a parameter defined as the system size of the finite approximation. The approximations capture the interdeparture times from an queue exactly and preserve the lag correlations of inter-event times of the departures from an queue up to lag ( - 1).

Analysis of a MX/G(a,b)/1 queueing system with vacation interruption

M. Haridass, R. Arumuganathan (2012)

RAIRO - Operations Research - Recherche Opérationnelle

Similarity:

In this paper, a batch arrival general bulk service queueing system with interrupted vacation (secondary job) is considered. At a service completion epoch, if the server finds at least ‘’ customers waiting for service say , he serves a batch of min (, b) customers, where  ≥ . On the other hand, if the queue length is at the most ‘-1’, the server leaves for a secondary job (vacation) of random length. It is assumed that the secondary job is interrupted abruptly and the server resumes...

The MX/M/1 queue with working breakdown

Zaiming Liu, Yang Song (2014)

RAIRO - Operations Research - Recherche Opérationnelle

Similarity:

In this paper, we consider a batch arrival //1 queue model with working breakdown. The server may be subject to a service breakdown when it is busy, rather than completely stoping service, it will decrease its service rate. For this model, we analyze a two-dimensional Markov chain and give its quasi upper triangle transition probability matrix. Under the system stability condition, we derive the probability generating function (PGF) of the stationary queue length, and...

Nash equilibria for a model of traffic flow with several groups of drivers

Alberto Bressan, Ke Han (2012)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

Traffic flow is modeled by a conservation law describing the density of cars. It is assumed that each driver chooses his own departure time in order to minimize the sum of a departure and an arrival cost. There are groups of drivers, The -th group consists of drivers, sharing the same departure and arrival costs (), (). For any given population sizes ,, , we prove the existence of a Nash equilibrium solution,...

An MX/G/1 unreliable retrial queue with two phase service and persistence behaviour of customers in service

M. Senthil Kumar, R. Arumuganathan (2013)

RAIRO - Operations Research - Recherche Opérationnelle

Similarity:

This paper describes an unreliable server batch arrival retrial queue with two types of repair and second optional service. The server provides preliminary first essential service (FES) to the primary arriving customers or customers from retrial group. On successful completion of FES, the customer may opt for second optional service (SOS) with probability . The server is subject to active break downs. The customer under FES (or SOS) during the failure decides, with probability , to join...

Entropy maximization and the busy period of some single-server vacation models

Jesus R. Artalejo, Maria J. Lopez-Herrero (2010)

RAIRO - Operations Research

Similarity:

In this paper, information theoretic methodology for system modeling is applied to investigate the probability density function of the busy period in vacation models operating under the -, - and -policies. The information about the density function is limited to a few mean value constraints (usually the first moments). By using the maximum entropy methodology one obtains the least biased probability density function satisfying the system's constraints. The analysis of the three controllable...

An Extended Opportunity-Based Age Replacement Policy

Bermawi P. Iskandar, Hiroaki Sandoh (2010)

RAIRO - Operations Research

Similarity:

The present study proposes an extended opportunity-based age replacement policy where opportunities occur according to a Poisson process. When the age, of the system satisfies for a prespecified value , a corrective replacement is conducted if the objective system fails. In case satisfies for another prespecified value , we take an opportunity to preventively replace the system by a new one with probability , and do not take the opportunity with probability . At the moment reaches...
