A Tour In Process Mining: From Practice to Algorithmic Challenges

Tuesday, June 27, 2017 – Zaragoza, Spain

Description

Data science is the profession of the future, because organizations that are unable to use (big) data in a smart way will not survive. It is not sufficient to focus on data storage and data analysis. The data scientist also needs to relate data to process analysis. Process mining bridges the gap between traditional model-based process analysis (e.g., simulation and other business process management techniques) and data-centric analysis techniques such as machine learning and data mining. Process mining seeks the confrontation between event data (i.e., observed behavior) and process models (hand-made or discovered automatically). This technology has become available only recently, but it can be applied to any type of operational processes (organizations and systems). Example applications include: analyzing treatment processes in hospitals, improving customer service processes in a multinational, understanding the browsing behavior of customers using booking site, analyzing failures of a baggage handling system, and improving the user interface of an X-ray machine. All of these applications have in common that dynamic behavior needs to be related to process models.

Hence, process mining considers the discovery of process models from real process executions. Discovered models may deviate from reality, and therefore a very important functionality in process mining, as important as discovery, is the automatic assestment of the quality of a process model in representing the reality, a discipline known as conformance checking. Taken together, discovery and conformance checking offer a powerful toolbox to organizations for improving their processes.

Process mining provides not only a bridge between data mining and business process management; it also helps to address the classical divide between “business” and “IT”. Evidence-based business process management based on process mining helps to create a common ground for business process improvement and information systems development.

In the research community related to the topics of the Petri Nets conference, process mining can be the killer application for many other disciplines such as formal methods, concurrency and distributed systems. In particular, the use of Petri nets has grown considerably due being the most popular representation for process mining algorithms.

The motivation of this tutorial is to provide an introductory tour to the field, and then the necessary background and practice so that an attendant can understand the current challenges the field of process mining is facing nowadays. Unlike some of the current textbooks or online courses for process mining, the tutorial will pay special attention to the conformance checking dimension, where some interesting challenges can be addressed.

Outline

This tutorial will consists of four modules.

  • Module I: A Practical Introduction to Process Mining (1h) – Introduction to process mining with demos of commercial tools (highlighting the incredible relevance and the limitations of existing tools).
  • Module II: Discovering Process Models (2h) – Process discovery with inductive mining as an example of scalable discovery technique. Process discovery with region-based approaches.
  • Module III: The Challenge of Alignments (1.5h) – Complexity issues for relating observed and modeled behavior. Formal definition of alignments. Selected techniques for the computation of alignments. Alignments applications.
  •  Module IV: Evidence-based Quality Metrics for Process Models(2h) – Current metrics for measuring the quality of process models with respect to observed behavior. Limitations of some of the discovery approaches.

Audience

The target audience includes research students as well as researchers. The tutorial is suitable for computer scientists and engineers familiar with basic process modelling approaches. For the case of the last module, the tutorial illustrates in depth the current algorithmic challenges, thus it might be of special interest to those looking for new challenges to their theoretical background.
