SIMUTools 2014 is the seventh edition of the annual International Conference on Simulation Tools and Techniques. The conference focuses on a broad range of research challenges in the field of simulation, modeling and analysis, addressing current and future trends in simulation techniques, models, practices and software. The conference is dedicated to fostering interdisciplinary collaborative research in these areas and across a wide spectrum of application domains. Building on the success of the previous six editions (2008-2013), this year's edition will provide an exciting forum for interaction among academic and industry researchers together with practitioners from both the simulation community and the different user communities.
