Equations

Formula for practitioners

$\sum _{i \in \mathit{inst}(c)} \mathit{U}(i)$

$\mathit{inst}(c)$ returns the set of all activity instances in case $c$ .
$\mathit{U}(i)$ returns the outcome unit count of activity instance $i$ .

Formal Definition

$\sum _{e \in \mathit{inst}(c)} \mathit{U}\mathit{^{\times}}(i)$
The $\mathit{\times}$ indicates that the PPI can take multiple forms, in this case, $\mathit{\times} \in \{\mathit{sgl}, \mathit{sum}\}$ . If $\mathit{\times} = \mathit{sgl}$ , then the function considers single events of activity instances for outcome unit calculations, i.e., it uses $\mathit{U}\mathit{^{sgl}}$ ; if $\mathit{\times} = \mathit{sum}$ , then the function considers the sum of all events of activity instances for outcome unit calculations, i.e., it uses $\mathit{U}\mathit{^{sum}}$ .
