Dataflow architectures are fundamental to achieve high performance in data-intensive applications. They must be optimized elaborate input data arriving at an expected rate, which is not always constant. While worst-case designs can significantly increase hardware resources, more optimistic solutions fail sustain execution phases with throughput, leading system congestion or even computational e...

In this paper, we address the issue of congestion in future Unmanned Aerial Vehicle (UAVs) traffic system uncertain weather. We treat UAVs as fluid queues, and introduce models for dynamics at three basic components: single link, tandem merge link. The impact weather uncertainty is captured fluctuation saturation rate queue discharge (capacity). assumed to follow a continuous-time Markov proces...

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...

Among the various existing models for the warehousing management, the simultaneous use of private and public warehouses is as the most well-known one. The purpose of this article is to develop a queuing theory-based model for determining the optimal capacity of private warehouse in order to minimize the total corresponding costs. In the proposed model, the available space and budget to create a...

Most of the real queuing systems include special properties and constraints, which can not be analyzed directly by using the results of solved classical queuing models. Lack of Markov chains features, unexponential patterns and service constraints, are the mentioned conditions. This paper represents an applied general algorithm for analysis and optimizing the queuing systems. The algorithm stag...

The paper is devoted on computer simulation of rare event probability, which is a critical issue in areas such as reliabilities, telecommunications, aircraft management, etc. This means that it is necessary to evaluate probabilityties less than 10, which is unreasonable to be simulated with standard Monte Carlo approach. M/M/1/N queuing system and tandem queuing system are under investigation w...
