Resource count

\mathit{R}(g)

Dimension:

Cost

Granularity:

Group of cases

Number of resources that are involved in the execution of a group of cases.

If the event log does not contain cost information, Resource count can be used as a proxy for the cost performance of a group of cases.

Minimizing the number of resources involved is desirable.

$\mathit{count}(\cup_{c \in g} \mathit{res}(c))$

$\mathit{res}(c)$ returns the set of unique resources involved in case $c$ .

$|\cup_{c \in g} \mathit{res}(c)|$

This indicator is implemented in the process_performance_indicators Python library.
