ON THE STARSHAPENESS OF G/G/c QUEUEING SYSTEMS
نویسندگان
چکیده
In this paper we show that the waiting and the sojourn times of a customer in a single-stage, multiple-server, G / G /c queueing system are increasing and starshaped with respect to the mean service time. Usefulness of this result in the design of the optimal service speed in the G / G /c queueing system is also demonstrated.

Emergency Location Problems with an M/G/k Queueing System
Since late 1960's, the emergency location problems, fire stations and medical emergency services have attracted the attention of researchers. Mathematical models, both deterministic and probabilistic, have been proposed and applied to find suitable locations for such facilities in many urban and rural areas. Here, we review some models proposed for finding the location of such facilities, wit...
متن کاملDilations for $C^ast$-dynamical systems with abelian groups on Hilbert $C^ast$-modules
In this paper we investigate the dilations of completely positive definite representations of (C^ast)-dynamical systems with abelian groups on Hilbert (C^ast)-modules. We show that if ((mathcal{A}, G,alpha)) is a (C^ast)-dynamical system with (G) an abelian group, then every completely positive definite covariant representation ((pi,varphi,E)) of ((mathcal{A}, G,alpha)) on a Hilbert ...
متن کاملComplete forcing numbers of polyphenyl systems
The idea of “forcing” has long been used in many research fields, such as colorings, orientations, geodetics and dominating sets in graph theory, as well as Latin squares, block designs and Steiner systems in combinatorics (see [1] and the references therein). Recently, the forcing on perfect matchings has been attracting more researchers attention. A forcing set of M is a subset of M contained...
متن کاملFormation and stability of Vitamin E nano-emulsion based delivery systems by spontaneous emulsification method: Glycerol as a co-solvent
There is considerable interest in using nano-emulsions (NEs) as delivery systems for lipophilicbioactive ingredients. In this study, the influence of G on the properties of vitamin E (VE) enriched NEsprepared using spontaneous emulsification (SE) method, were investigated. The particle size and optical clarityof the NEs depended strongly on the co-solvent presence, absence, an...
متن کاملAnalysis of M/G/ 1 queueing model with state dependent arrival and vacation
This investigation deals with single server queueing system wherein the arrival of the units follow Poisson process with varying arrival rates in different states and the service time of the units is arbitrary (general) distributed. The server may take a vacation of a fixed duration or may continue to be available in the system for next service. Using the probability argument, we construct the ...
