Formula for practitioners

$\sum_{i \in \mathit{inst}(c),\, \mathit{act}(i) \in \mathit{Autl}} \mathit{ST}(i)$

$\mathit{inst}(c)$ returns the set of activity instances that occur in case $c$.
$\mathit{act}(i)$ returns the activity associated with activity instance $i$.
$\mathit{Autl}$ denotes the set of automated activities.
$\mathit{ST}(i)$ returns the service time of activity instance $i$.
