Queuing is common in urban public places. Automatically monitoring and predicting queuing time can not only help individuals to reduce their wait time and alleviate anxiety but also help managers to allocate resources more efficiently and enhance their ability to address emergencies. This paper proposes a novel method to estimate and predict queuing time in indoor environments based on WiFi pos...

In this paper, we proposed a new multistage virtual shared memory model for cluster based parallel systems. This model can be expanded in hierarchical manner and covered many of the previous clusters of parallel system designs. Queuing theory and Jackson queuing networks are applied for constructing an analytical model. This model gives a closed-form solution for the system performance metrics,...

Motivated by the problems encountered in the operation of the front end of a grocery store, a queuing model is formulated for a variable channel queuing system. A cost structure is superimposed over the queuing model and after examining the customer jockeying properties of the system, an optimal operating policy is generated. The practical aspects of the generation and implementation of an opti...

PRP (Psychological Refractory Period) is a basic but important form of human information processing in dual-task situations. This article describes a queuing network model of PRP that successfully modeled PRP without the need of setting up complex lock/unlock performance strategies employed in the EPIC model of PRP or drawing complex scheduling charts employed in the ACT-R/PM model of PRP. Furt...

Many studies have indicated the importance of capturing scaling properties when modeling traffic loads; however, the influence of long-range dependence (LRD) and marginal statistics still remains on unsure footing. In this paper, we study these two issues by introducing a multiscale traffic model and a novel multiscale approach to queuing analysis. The multifractal wavelet model (MWM) is a mult...

The paper explains the main idea of how the Estelle semantics may be reinterpreted within the queuing network model making possible a translation of Estelle into the algorithmic language of the Queuing Network Analysis Package (QNAP2). Such a translation gives access to all utilities of the package and enables the performance analysis to be integrated into the design process of Estelle specific...

A framework for stochastic traffic flow modeling over the U. S. National airspace based on queuing network models is advanced. The proposed framework allows the inclusion of a wide variety of trajectory uncertainties such as delays due to weather deviation, air traffic control actions, en route wind, aircraft performance, navigation system precision and flight control. En route queuing networks...

 In this paper we develop queuing model results for a single “automated” workstation that receives jobs from another automated workstation. An automated workstation is a server with deterministic processing times that experiences random operating times between failures, and then subsequent random repair times. We develop analytical expressions for the queue size distribution, the average numbe...

In cellular systems there is usually an overlap cell coverage area (area covered by two or more base stations) which has valuable practical applications. Particularly, it permits the queuing of handover requests as a handover prioritization scheme. The modeling of the sojourn time in the overlap area is a topic which is not sufficiently explored, and even less is the effect it may have on the p...
