Zusammenfassung
The key points of this article are:
The authors propose a methodology grounded in the CRISP-DM framework for evaluating agent-based simulation
(ABS) models using process mining techniques. The methodology consists of six phases: Contextual Understanding,
Data and Tool Understanding, Data Preparation, Modeling, Evaluation, and Deployment.
The authors demonstrate the application of the proposed methodology using Schelling's model of segregation, a
seminal example in the domain of ABS models. They focus on examining the impact of outlier behaviors on the
validity of the ABS model.
In the Modeling phase, the authors use process mining techniques, such as the Fuzzy Miner algorithm, to extract
process models and insights from the ABS model's event logs. They then assess the plausibility of these insights
through a face validity check with a human expert.
The results of the face validity assessment show a mix of outcomes, with some observations deemed plausible,
some requiring further investigation, and others deemed not plausible. This highlights the potential of process
mining techniques to identify both valid and invalid behaviors in ABS models.
The authors discuss the limitations of their approach, such as the reliance on a single human expert for the face
validity assessment, and the challenges in representing the iterative nature of the methodology in a linear format.
They also emphasize the need for more rigorous and procedural approaches to validate ABS models.
Overall, this article contributes a structured methodology for leveraging process mining techniques to evaluate
the validity of ABS models, using Schelling's segregation model as an illustrative case study.
Statistiken
The simulation model runs until it achieves a specified convergence level of happiness (of 100%) or completes a
specified number of steps (100 in this case).
The event log used in the case study contains 20,024 events, 280 cases, and 46 activities.
Zitate
"Applying process mining techniques combined with ABS has proven its effectiveness, as further showcased in
Section 2."
"Our methodology offers: (1) a guideline for the steps to undertake when applying process mining techniques to
assess event logs generated by an agent-based system; and (2) an endeavor to enhance the replicability and
transparency of combined ABS and process mining research by adapting a well-established data science project
methodology."
