$\displaystyle \sum_{c \in g} \begin{cases} 1 & \text{if } \mathit{RewC}(c) > 0 \\ 0 & \text{otherwise} \end{cases}$

$\mathit{RewC}(c)$ returns the rework count for case $c$ .

$|\{c \in g \mid \mathit{RewC}(c) > 0\}|$

This indicator is implemented in the process_performance_indicators Python library.
