The 21 full papers and 2 short papers presented together with 2 keynote papers were carefully reviewed and selected from 47 submissions. The papers are organized in the following topics: probabilistic model checking; quantitative models and metamodels: analysis and validation; queueing systems; learning and verification; simulation; performance evaluation; abstractions and aggregations; and stochastic models.Theoretical Computer Science and General Issues,2512-2029 ;12846Computer scienceComputer scienceMathematicsMathematical statisticsArtificial intelligenceSoftware engineeringAlgorithmsMachine theoryTheory of ComputationProbability and Statistics in Computer ScienceArtificial IntelligenceSoftware EngineeringAlgorithmsFormal Languages and Automata TheoryComputer science.Computer scienceMathematics.Mathematical statistics.Artificial intelligence.Software engineering.Algorithms.Machine theory.Theory of Computation.Probability and Statistics in Computer Science.Artificial Intelligence.Software Engineering.Algorithms.Formal Languages and Automata Theory.004.24Abate AlessandroMarin AndreaMiAaPQMiAaPQMiAaPQBOOK9910495168603321Quantitative Evaluation of Systems2914390UNINA
