Recursive models have been used in the past to model the variation of number of processes in all the queuing systems of heterogeneous parallel computer system. The main reasons for the use of recursive models when modeling the variation of number of processes in all the queuing systems of a heterogeneous parallel computer system is the inability of the analytic technique to determine the exact ...
BACKGROUND Changes in patient length of stay (the duration of 1 clinic visit) as a result of the introduction of an electronic patient file system forced an anesthesia department to change its outpatient clinic organization. In this study, we sought to demonstrate how the involvement of essential employees combined with mathematical techniques to support the decision-making process resulted in ...
We present a new hybrid approach to performance management, combining disparate strengths of Reinforcment Learning (RL) with model-based (e.g. queuing-theoretic) approaches. Our method trains nonlinear function approximators using offline RL on data collected while a model-based policy controls the system. By training offline we avoid potentially poor performance in live online training, while ...
Queuing networks are popular us models of performance of computer systems and communication networks. The Research Queueing Package, Version 2 (RESQ2), is a system ,for constructing and solving extended queuing network models. We refer to the class of RESQ2 networks as “extended” because of characteristics absent from most queuing models, RESQ2 incorporates a high-level language to concisely de...
Today’s Internet only provides Best Effort Service. Traffic is processed as quickly as possible, but there is no guarantee of timelines or actual delivery. With the rapid transformation of the Internet into a commercial infrastructure, demands for service quality have rapidly developed. People of the modern world are very much dependent on various network services like VOIP, Videoconferencing a...
The primary goal of future cellular mobile communication networks is to provide efficient and cost effective services to mobile users under all environments. The major issues that affects the quality of service and performance in wireless communications systems is scarcity of resources. Hence, efficient resource allocation is prime concern in order to improve the performance of cellular network...
In this paper, we present an analysis for an M/Ek/1 queuing system with balking and state-dependent service. Customers are served with two different rates depending on the number of customers in the system. If a customer on arrival finds other customers in the system, it either decides to enter the queue or balks with a constant probability. We first formulate the queuing model as a quasi-birth...
paper provides a nontechnicul introduction to queuing network concepts, a short introduction to results of research into analytical modeling methodology, and u set of simple but typical examples that illustrute the upplication of that methodology to problems of computer perfbrmunce. The objectives of this paper are to introduce concepts of the theory of queuing networks, to describe an APL prog...
While today's computer networks supports only best-effort service, future packet-switching integrated-services networks will have to support real-time communication services that allow clients to transport information with performance guarantees expressed in terms of delay, delay jitter throughput and loss rate. An important issue in providing guaranteed performance service is the choice of pac...
