Lead Time Deviation from time Limit

\mathit{LTDL}(c, \mathit{val})

Dimension:

Time

Granularity:

Case

Description

Difference between the time that a case is expected to take and its lead time.

Potential use

Event log is associated with a process in which the lead time of a case should not exceed a specific value.

Assumptions

Exceeding the lead time limit value is undesired.

Desired Value:

MAXIMIZE

Formula for practitioners

$val - \mathit{LT}(c)$

$\mathit{LT}(c)$ returns the lead time of case $c$ .
$val$ represents the predefined time Limit for the case.
The expression $|val - \mathit{LT}(c)|$ measures the absolute deviation of the case lead time from its deadline.

Formal Definition

$\mathit{val} - \mathit{LT}(c)$

Python implementation

This indicator is implemented in the process_performance_indicators Python library.
