Analyzing Web Server Performance Models with the Probabilistic Model Checker PRISM

by Tamás Bérczes, Gábor Guta, Gábor Kusper, Wolfgang Schreiner, János Sztrik - Johannes Kepler University , 2008
"... We report our experience with formulating and analyzing in the probabilistic model checker PRISM various closely related web server performance models that were previously described in literature in terms of classical queuing theory. By our work various ambiguities and deficiencies (also errors) are ..."

Using the Probabilistic Model Checker PRISM to Analyze Credit Card Use

by Amani El Rayes, Mevliyar Er
"... Abstract: Probabilistic model checking is a recent extension of traditional model-checking techniques for the integrated analysis of both qualitative and quantitative properties of systems which exhibit stochastic behaviour. In this paper we apply probabilistic model checking to study the effect of ..."

PRISM: Probabilistic symbolic model checker

by Marta Kwiatkowska, Gethin Norman, David Parker , 2002
"... Abstract. In this paper we describe PRISM, a tool being developed at the University of Birmingham for the analysis of probabilistic systems. PRISM supports two probabilistic models: continuous-time Markov chains and Markov decision processes. Analysis is performed through model checking such systems ..."

On probabilistic model checking

by Marta Kwiatkowska, Gethin Norman, David Parker , 1996
"... Abstract. This tutorial presents an overview of model checking for both discrete and continuous-time Markov chains (DTMCs and CTMCs). Model checking algorithms are given for verifying DTMCs and CTMCs against specifications written in probabilistic extensions of temporal logic, including quantitative ..."

Variations on itai-rodeh leader election for anonymous rings and their analysis in prism

by Wan Fokkink, Jun Pang - Journal of Universal Computer Science
"... Abstract: We present two probabilistic leader election algorithms for anonymous unidirectional rings with FIFO channels, based on an algorithm from Itai and Rodeh [Itai and Rodeh 1981]. In contrast to the Itai-Rodeh algorithm, our algorithms are finite-state. So they can be analyzed using explicit s ..."
