Potential use

Event log that contains automated activities and cost information.

Assumptions

Minimizing total cost is desirable.

Desired Value:

MINIMIZE

Formula for practitioners

$\frac{\mathit{AutC}(g)}{\mathit{C}(g)}$

$\mathit{AutC}(g)$ returns the total automated activity cost for group $g$ .
$\mathit{C}(g)$ returns the number of cases in group $g$ .

Formal Definition

$\frac{\mathit{AutC}\mathit{^{\times}}(g)}{\mathit{C}(g)}$
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 cost calculations, i.e., it uses $\mathit{AutC}\mathit{^{sgl}}$ ; if $\mathit{\times} = \mathit{sum}$ , then the function considers the sum of all events of activity instances for cost calculations, i.e., it uses $\mathit{AutC}\mathit{^{sum}}$ .
