Expected activity Instance count

\mathit{e}\mathit{I}(g)

Dimension:

Time

Granularity:

Group of cases

Expected number of times that any activity is instantiated in a case belonging to a group of cases.

If the event log does not contain timestamps, Expected activity Instance count can be used as a proxy for the time performance of a group of cases.

A greater number of activity instances implies that a case takes longer to complete.

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

$\mathit{I}(g)$ returns the activity instance count of group of cases $g$ .
$\mathit{C}(g)$ returns the case count of group of cases $g$ .

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