 To handle the scalability issue, we adopt a simulation-based
 approach, backed up by the \emph{scenario
 theory}~\cite{calafiore2006scenario}, that \emph{empirically}
 performs the uncertainty characterization, and provides
 \emph{formal guarantees} on the robustness of the resulting
-estimation. The scenario theory is capable of exploiting the fact
-that simulating the taskset execution (with statistical significance)
-is less computationally expensive than an analytical approach that
-incurs into the problem of combinatorial explosion of the different
-possible uncertainty realizations. In practice, this means that we:
-(i) randomly extract execution times from the probability
-distributions specified for each task, $f_i^{\mathcal{C}}(c)$, (ii)
