ST(c)\mathit{ST}(c)
Dimension:
Time
Granularity:
Case

Description

Sum of elapsed time between the start and complete events of all activity instances of a case.

Potential use

Event log that contains lifecycle information for activity instances where the actual time spent executing them is of interest.

Assumptions

Minimizing service time is desirable.

Desired Value:

MINIMIZE

Formula for practitioners

iinst(c)ST(i)\sum _{i \in \mathit{inst}(c)} \mathit{ST}(i)

inst(c)\mathit{inst}(c) returns the set of all activity instances in case cc.
ST(i)\mathit{ST}(i) returns the service time of activity instance ii.

Formal Definition

iinst(c)ST(i)\sum _{i \in \mathit{inst}(c)} \mathit{ST}(i)
