ValueTools 2012 is an interdisciplinary conference whose goal is to gather and to facilitate the flow of expertise between researchers from different communities working on performance evaluation, optimization, and stochastic modeling in complex systems.

Owing to recent technological advances and the massive connectivity of our "always-online" era, these issues have attracted considerable interest in the fields of Computer Science, Control Theory, Networks and Telecommunications, Operations Research, Optimization, and Signal Processing, and, traditionally, all these communities have had a strong presence in the organization and steering of the conference. Correspondingly, ValueTools 2012 solicits previously unpublished contributions that propose new performance evaluation methodologies (or help clarify the limitations of older ones) in practical complex scenarios, and new tools (or novel applications of already established ones) with which to control the performance of complex systems where traditional methods have failed to produce appealing results.
