This paper studies and gives an analysis of a particular queuing model. It considers a non-preemptive priority queuing system with K ( ≥ 2 ) classes of jobs. The system consists of a single processor. It represents the model of discrete dynamic scheduling problems associated with M k / Gk / 1 / ∞ endogenous priority queues. The processor schedule jobs arriving according to a Markov arrival proc...

In this paper, an analytical framework is developed to evaluate the performance of complete sharing (CS) with two different handover priority schemes for multi-class traffic in Low Earth Orbit-Mobile Satellite Systems (LEO-MSS). In the first priority scheme, the handover requests are given the higher priority using queuing scheme with also taking into consideration the priority between classes ...

This paper presents one of the features of DS (Differentiated Services) architecture, namely the queuing or congestion management. Packets can be placed into separate buffer queues, on the basis of the DS value. Several forwarding policies can be used to favor high priority packets in different ways. The major reason for queuing is that the router must hold the packet in its memory while the ou...

This article presents an hybrid priority queuing model based scheduler for real-time traffic differentiation. The proposed scheduler is designed as a mechanism to provide queuing delay differentiation among real-time traffic classes. The novel characteristic of the presented scheduler is the capability to simultaneously try to achieve an upper time limit for queuing delays and, under heavy load...

In CT examination, the emergency patients (EPs) have highest priorities in the queuing system and thus the general patients (GPs) have to wait for a long time. This leads to a low degree of satisfaction of the whole patients. The aim of this study is to improve the patients' satisfaction by designing new queuing strategies for CT examination. We divide the EPs into urgent type and emergency typ...

In this paper we report on a study of a two level preemptive priority queue with balking and reneging for lower priority level. The inter-arrival and the service times for both levels follow exponential distribution. We use a finite difference equation approach for solving the balance equations of the governing queuing model whose states are described by functions of one independent variable. H...

This article provides an effective method to analyze the performance measures of non-preemptive fuzzy priority queues with unequal service rates. Here arrival rate and are in numbers. Using a new ranking method, values reduced crisp values. For that cause, both Triangular Fuzzy Number (TFN) Trapezoidal (TpFN) chosen establish proposal's effectiveness. An illustration is given find efficiency qu...
