In this paper, we analyse Stochastic Petri Net (SPN) models of slotted-ring networks. We show that a simple SPN model of a slotted-ring network, which exhibits a productform solution, yields similar results to a more detailed SPN model that has to be analysed by numerical means. Furthermore, we demonstrate a Mean-Value Analysis (MVA) approach to calculate efficiently the results for the simple ...

Approximate Mean Value Analysis (MVA) is a popular technique for analyzing queueing networks because of the efficiency and accuracy that it affords. In this paper, we present a new software package, called the Improved Approximate Mean Value Analysis Library (IAMVAL), which can be easily integrated into existing commercial and research queueing network analysis packages. The IAMVAL packages inc...

to study the changes of serum uric acid level which is influenced by various factors including nutrition, race, socio-economic conditions age, sex, obesity and hyper lipidemia, a wide variety of survey appeared to be performed. for this study in six large provinces of iran out of 12,524 apparently healthy individuals a total of 2,744 persons of both sexes (1,439 females, 1,305 males) were selec...

The conditional mean value has applications in regression analysis and financial mathematics, because they are used it. We can find papers from recent years that use the fuzzy cases. As intuitionstic sets an extension of sets, we will try to define a for intuitionistic case. crisp events was first studied by V. Valenčáková 2009. She Gödel connectives. Her approach only be special cases events, ...
