—In this paper, we propose an analytical approach to predict the performance of web service composition built on BPEL. The approach first translates web service composition specification into Stochastic Petri Nets. From the SPN model and its corresponding continuous-time Markov chain, we derive the analytical performance estimates of(More)
In recent decades, the approach known as Finite-Time Thermodynamics has provided a fruitful theoretical framework for the optimization of heat engines operating between a heat source (at temperature hs T) and a heat sink (at temperature cs T). The aim of this paper is to propose a more complete approach based on the association of Finite-Time Thermodynamics(More)
In recent decades, the approach known as Finite-Dimension Thermodynamics has provided a fruitful theoretical framework for the optimization of heat engines operating between a heat source (at temperature T hs) and a heat sink (at temperature T cs). We will show in this paper that the approach detailed in a previous paper [1] can be used to analytically(More)
