Object-Centric Alignments
Lukas Liss, Jan Niklas Adams, Wil M.P. van der Aalst

TL;DR
This paper introduces an alignment approach for object-centric processes that preserves inter-object dependencies, providing better insights into complex process behaviors and interactions.
Contribution
It defines object-centric alignments, proposes an algorithm to compute them, and evaluates their effectiveness and computational challenges.
Findings
Object-centric alignments improve process insight by considering inter-object dependencies.
Run-time complexity grows exponentially with process size and complexity.
The approach is validated through qualitative and quantitative evaluations.
Abstract
Processes tend to interact with other processes and operate on various objects of different types. These objects can influence each other creating dependencies between sub-processes. Analyzing the conformance of such complex processes challenges traditional conformance-checking approaches because they assume a single-case identifier for a process. To create a single-case identifier one has to flatten complex processes. This leads to information loss when separating the processes that interact on some objects. This paper introduces an alignment approach that operates directly on these object-centric processes. We introduce alignments that can give behavior-based insights into how closely related the event data generated by a process and the behavior specified by an object-centric Petri net are. The contributions of this paper include a definition for object-centric alignments, an…
