Directly-Follows Relations count

\mathit{DFR}(g)

Dimension:

Flexibility

Granularity:

Group of cases

Number of activity pairs where one is instantiated directly after the other in a group of cases.

Process where several distinct directly-follows relations can occur.

A greater number of directly-follows relations is desirable, as it implies a greater capability to address unexpected situations.

$\displaystyle \sum_{r \in (\cup_{c \in g} \mathit{dfrel}(c))} 1$

$\mathit{dfrel}(c)$ returns the set of unique Directly-Follows Relations (DFR) in case $c$ .

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

This indicator is implemented in the process_performance_indicators Python library.
