Total cost associated with an activity instance, measured as the latest recorded value among the events of an activity instance.

Event log in which total cost information is recorded.

Minimizing total cost is desirable.

Formula for practitioners

$\begin{cases} \#^{}_{\mathit{tc}}(\mathit{cpl}(i)) & \mathit{if \ } \#^{}_{\mathit{tc}}(\mathit{cpl}(i)) \neq undefined \\ \#^{}_{\mathit{tc}}(\mathit{str}(i)) & \mathit{if \ } \#^{}_{\mathit{tc}}(\mathit{cpl}(i)) = undefined \land \#^{}_{\mathit{tc}}(\mathit{str}(i)) \neq undefined \\ undefined & \mathit{if \ } \#^{}_{\mathit{tc}}(\mathit{cpl}(i)) = undefined \land \#^{}_{\mathit{tc}}(\mathit{str}(i)) = undefined \\ \end{cases}$

$\#^{}_{\mathit{tc}}$ returns the total cost associated with an event.
$\mathit{cpl}(i)$ returns the completion event of activity instance $i$.
$\mathit{str}(i)$ returns the start event of activity instance $i$.
