Gran Sasso Science Institute

GSSI is an international PhD school and a research center for advanced studies in Computer Science, Mathematics, Physics, and Social Sciences, see more details here: http://www.gssi.it My main research interests:

  • model-based

performance analysis

  • probabilistic model-

checking

Challenges for composing new tools

§ Collaborative model-based analysis

§

Investigate the combined use of different QoS models for a collaborative analysis

§ Uncertainty reduction

§

Look for strategies on how to acquire further knowledge on system uncertainties

§ Quality-based refactoring

§

Improve the quality-based characteristics by devising effective model-based changes
