Automated Discovery of Process Models with True Concurrency and Inclusive Choices
This addresses a gap in process mining for enterprise systems by enabling more accurate modeling of overlapping activities, though it is an incremental improvement on an existing method.
The paper tackles the problem that existing automated process discovery techniques fail to capture true concurrency in business processes, and presents a refined version of Split Miner that discovers true concurrency relations and differentiates between exclusive and inclusive choices, achieving improved accuracy over baselines on 11 real-life logs.
Enterprise information systems allow companies to maintain detailed records of their business process executions. These records can be extracted in the form of event logs, which capture the execution of activities across multiple instances of a business process. Event logs may be used to analyze business processes at a fine level of detail using process mining techniques. Among other things, process mining techniques allow us to discover a process model from an event log -- an operation known as automated process discovery. Despite a rich body of research in the field, existing automated process discovery techniques do not fully capture the concurrency inherent in a business process. Specifically, the bulk of these techniques treat two activities A and B as concurrent if sometimes A completes before B and other times B completes before A. Typically though, activities in a business process are executed in a true concurrency setting, meaning that two or more activity executions overlap temporally. This paper addresses this gap by presenting a refined version of an automated process discovery technique, namely Split Miner, that discovers true concurrency relations from event logs containing start and end timestamps for each activity. The proposed technique is also able to differentiate between exclusive and inclusive choices. We evaluate the proposed technique relative to existing baselines using 11 real-life logs drawn from different industries.
