چکیده

We introduce a product-form approximation for tandem networks with Poisson arrivals and non-exponential service times. The proposed technique perturbates the model state space to match the sufficient conditions for product-form solution provided by the Compound Reversed Agent Theorem (RCAT). After characterizing the relation between RCAT product-forms and matrix geometric solutions, we develop an algorithm based on nonlinear programming that automatically searches for an approximating product-form model.

Using Fluid Queues to Model Energy Storage and Distribution

Energy storage and distribution is an increasingly important problem as renewable (and generally unreliable) energy sources supply more of our power needs. In this extended abstract we consider a simple network of energy suppliers, consumers and buffers modelled as fluid queues. Analytical evaluation of networks of fluid queues is hard as even tandem networks do no have a product form solution....

Analysis and Approximation of Dual Tandem Queues with Finite Buffer Capacity

Tandem queues with finite buffer capacity commonly exist in practical applications. By viewing a tandem queue as an integrated system, an innovative approach has been developed to analyze its performance through the insight from Friedman's reduction method. Fundamental properties of tandem queues with finite buffer capacity are examined. We show that in general system service rate of a dual tan...

GDOP Classification and Approximation by Implementation of Time Delay Neural Network Method for Low-Cost GPS Receivers

Geometric Dilution of Precision (GDOP) is a coefficient for constellations of Global Positioning System (GPS) satellites. These satellites are organized geometrically. Traditionally, GPS GDOP computation is based on the inversion matrix with complicated measurement equations. A new strategy for calculation of GPS GDOP is construction of time series problem; it employs machine learning and artif...

بررسی تحلیل عددی ورقهای نازک ایزوتروپ و ارتوتروپ بکمک روش بدون شبکه گالرکین (EFG) با اشکال هندسی گوناگون

Utilizing one of the mesh free methods, the present paper concerns static analysis of thin plates with various geometric shapes based on the mindlin classical plate theories. In this numerical method, the domain of issue is solely expressed through a set of nods and no gridding or element is required. To express the domain of issues with various geometric shapes, first a set of nodes are define...
