A Dynamic Non-preemptive Priority Queueing Model with Two Types of Customers

open access: yes, 2018
In this paper, we study a single-server non-preemptive priority queueing model with two types of customers. The customers arrive according to two independent Poisson processes, and the service times are exponential with possibly different parameters ...

ANALYSIS OF MULTI-SERVER QUEUEING SYSTEM WITH PREEMPTIVE PRIORITY AND REPEATED CALLS

open access: yesInformatika, 2016
Multi-server retrial queueing system with no buffer and two types of customers is analyzed as the model of cognitive radio system. Customers of type 1 have a preemptive priority.

Waiting Time Distributions in the Preemptive Accumulating Priority Queue [PDF]

open access: yes, 2017
The final publication is available at Springer via http://dx.doi.org/10.1007/s11009-015-9476-1We consider a queueing system in which a single server attends to N priority classes of customers.

Preemptive Software Project Scheduling Considering Personality Traits

open access: yesSystems
The success of software projects is inseparable from the effective scheduling of multi-skilled human resources. In software development, employees’ personality traits often affect the performance of their work.

ACCESS NETWORKs WITH THE RELATIVE PRIORITY

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2019
The engineering method of calculation of an average waiting time on priority classes a non-preemptive priority model of the exponential server as tool base of measurement of quality of service in networks with switching of packages is developed.

Optimizing Priority Queuing Systems with Server Reservation and Temporal Blocking for Cognitive Radio Networks

open access: yesTelecom
In the domain of cognitive radio (CR), unlicensed users have the opportunity to efficiently use available spectrum bands without interfering with licensed primary users (PUs). Our study addresses the challenge of secondary user (SU) spectrum shortage due

Flow-times in an M/G/1 Queue under a Combined Preemptive/Non-preemptive Priority Discipline.: Scheduled Waiting Time on Single Track Railway Lines [PDF]

open access: yes, 2010
A priority based rule for use during the process of scheduling trains oper- ating on a single track railway line was proposed by the Norwegian railway operator and owner, Jernbaneverket.

Delay Analysis of a Discrete-Time Non-Preemptive Priority Queue with Priority Jumps [PDF]

open access: yes, 2014
In this paper, we consider a discrete-time non-preemptive priority queueing model with priority jumps. Two classes, real-time (high priority) and non-real time (low priority), of traffic will be considered with providing jumps from lower priority traffic

Improving achievable traffic load of cognitive wireless networks under GoS constraints

open access: yesTongxin xuebao, 2012
To improve the achievable traffic load of secondary user(SU) under grade of service (GoS) constraints in cognitive wireless networks with heterogeneous traffic,a novel spectrum sharing scheme was proposed.The key idea of the proposed scheme was to ...

Modeling Fixed-Priority Preemptive Multi-Task Systems in SpecC

open access: yes, 2001
Many real-world embedded systems employ a preemptive scheduling policy in order to satisfy their real-time requirements. However, most System-Level Design Languages (SLDLs) which were proposed up to now, such as SpecC, do not explicitly support modeling ...
