Application of mixture of exponentials distributions for modeling queuing systems [PDF]

open access: yesLietuvos Matematikos Rinkinys, 2008
The article considers approximation of positive distribution functions by mixture of exponentials distributions. This approximation enables to model non-markovian queuing systems by Markov process with continuous time and countable set of states.

From multiplicity of infection to force of infection in sparsely sampled high-transmission Plasmodium falciparum populations [PDF]

open access: yeseLife
High multiplicity of infection (MOI), the number of genetically distinct parasite strains co-infecting a host, characterizes falciparum malaria and other infectious diseases under high transmission.

The Application of Phase Type Distributions for Modelling Queuing Systems [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2007
Queuing models are important tools for studying the performance of complex systems, but despite the substantial queuing theory literature, it is often necessary to use approximations in the case the system is nonmarkovian.

An Integrated Model of Patient and Staff Satisfaction Using Queuing Theory [PDF]

open access: yes, 2015
This paper investigates the connection between patient satisfaction, waiting time, staff satisfaction and service time. It uses a variety of models to enable improvement against experiential and operational health service goals.

Algorithms and error bounds for multivariate piecewise constant approximation [PDF]

open access: yes, 2010
We review the surprisingly rich theory of approximation of functions of many vari- ables by piecewise constants. This covers for example the Sobolev-Poincar´e inequalities, parts of the theory of nonlinear approximation, Haar wavelets and tree ...

APPROXIMATIONS TO PERFORMANCE MEASURES IN QUEUING SYSTEMS

open access: yesThe South African Journal of Industrial Engineering, 2012
Approximations to various performance measures in queuing systems have received considerable attention because these measures have wide applicability. In this paper we propose two methods to approximate the queuing characteristics of a GI/M/1 system.

Modelling of non‐Markovian queuing systems

open access: yesTechnological and Economic Development of Economy, 2006
The purpose of this paper is to suggest a method and software for evaluating queuing approximations. A numerical queuing model with priorities is used to explore the behaviour of exponential phase‐type approximation of service‐time distribution.

Numerical Approximation of 5G-V2V Physical Sidelink Shared Channel (PSSCH) Capacity Limit using M/G/1 Queuing and Newton–Raphson Method

open access: yesAlexandria Engineering Journal, 2023
3GPP 5G V2X technology promised some advanced vehicle safety driving use cases in the future. Vehicle to vehicle communications (V2V) is the pivotal enabler in 5G-V2X by allowing the exchange of Cooperative Awareness Message (CAM) over the Physical ...

Korisnički aspekt prelaznog režima rada sistema masovnog opsluživanja / Practical aspects of the transient regime in queuing systems

open access: yesVojnotehnički Glasnik, 2007
Problem početnog, prelaznog, nestacionarnog perioda ili perioda zagrevanja postoji niz decenija, kao važan i još uvek aktuelan problem u simulacionom modelovanju sistema masovnog opsluživanja (SMO). Uz primenu jedne teorijske aproksimacije za određivanje

Managing Dynamic Enterprise and Urgent Workloads on Clouds Using Layered Queuing and Historical Performance Models [PDF]

open access: yes, 2011
The automatic allocation of enterprise workload to resources can be enhanced by being able to make what-if response time predictions whilst different allocations are being considered.
