In a heterogeneous distributed memory parallel computer system, each of the processors has its own memory. Describing the system using queuing network, each of the processors has its own ready queue. Since the system has many I/O queues and I/O processors, therefore, the various processors with their various ready queues and the various I/O processors and their various I/O queues form the queui...

Objectives: This study aims to analyze the accuracy of queuing models and application layout design at gas station in Ngasinan Wonosobo, Indonesia. Fuel service providers are encouraged optimize space as number motorized vehicle customers grows. The focus attention management is not only on model, but also that acceptable adequate for customers, particularly motorcycle riders who use Pertalite....

In this paper a new structure is proposed for the massive parallel processing systems. This structure is expandable in vertical and horizontal manner and cover many of the previous computer designs. The queuing theory and Jackson queuing network is applied for constructing an analytical model for the proposed structure. This model gives a closed-form solution for the system performance metrics,...

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...

Two common approaches for predicting the response times of distributed enterprise applications on new server architectures are solving queuing models and extrapolating from previously gathered performance data. The dynamic recalibration of a layered queuing model and a historical model is investigated experimentally using the IBM Websphere Performance Sample benchmark. It is found that these mo...

This paper presents a detailed web server performance analysis for a company whose website has performance problems – their customers have been experiencing long response times and high rejection rates. In order to analyze and solve the problem, two queuing models are suggested: M/M/1/L and IPP/M/1/L. Relevant parameters for both queuing models are estimated, and a simulation for each model is ...

How to sustainably conduct intersection operations is a key issue of the current research. For an actuated control intersection, queued vehicles, parameters, and phase schemes all affect operation effect. This paper discusses vehicles at intersections their influence on signal timing. First, this establishes improved traffic wave model proposes vehicle queuing basis. Second, by analyzing disper...

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 potential benefit from introducing trajectory based operations into the NAS is estimated in this paper. Delay predictions of a stochastic and a deterministic queuing model, which represent high and low levels of trajectory uncertainty, are compared. It is found that delay savings are on the order of 35% in the average case, Delay predictions from the various models are found to be strongly ...
