Operational Semantics for Product-Form Solutione product-form solutions for a formalism called Labelled Markov Automata (LMA). LMA are very useful as their relation with the Continuous Time Markov Chains is very direct. The disadvantage of using LMA is that the proofs of properties are cumbersome. In fact, in LMA it is not possible to use the in

Scale-Freeness of SPA Models with Weighted Immediate Actionsdoes not affect the resulting overall model. A classical weighted approach, which is independent of rescaling weights in submodels, is the WSCCS approach by Tofts. The stochastic process algebra CASPA also uses weights, but the results are in general not independent of rescaling the submodels’ weigh

Experimental Evaluation of the Performance-Influencing Factors of Virtualized Storage Systemss to increase resource efficiency. In I/O-intensive applications, however, the virtualized storage of such shared environments can quickly become a bottleneck and lead to performance and scalability issues. In software performance engineering, application performance is analyzed to assess the non-fu

Tradeoff between Accuracy and Efficiency in the Time-Parallel Simulation of Monotone Systemsted to the initial state of the simulation to derive upper and lower bounds of the sample-paths. For a finite state space with some structural constraints, we prove that the algorithm provides bounds at the first step. These bounds are improved at every fix-up computation steps leading to a natural

Compositional Approximate Markov Chain Aggregation for PEPA Modelstwo different approaches to obtain a nearly optimal partition of the state-space, based on different notions of approximate state equivalence..Both approximate aggregation methods require an explicit representation of the transition matrix, a fact that renders them inefficient for large models.

A Path Connection Availability Model for MANETs with Random Waypoint Mobilityrious degrees of system dynamics. In addition, the connection availability of paths can be used as a global measure for the performance of ad hoc networks. To the best of our knowledge, there is no analytical study that provides a closed form solution for analytical analysis of connection availabili
