Generalized Conformance Checking

Recently, we submitted a work to the BPM conference with the title “In Log and Model We Trust? – A Generalized Conformance Checking Framework”.
The work is dealing with a problem, where we are given a process log and a process model, but both can have errors. That is, we might have different degrees of trust in the correctness of each of the artifacts. Imagine a process model created by a novice, or not capturing the process in it’s entirety. In this situation we might want to pull the model closer to the behavior reflected in the log. Conversely, the log can also have anomalies, outliers, noise or missing entries. Then, we might have a lower degree of trust in the log and want to pull it more towards the modeled behavior.

The proposed approach solves both problems in one go, when it tries to find a model-log pair that is well-fitting each other, and also not too far away from the input model and input log (in terms of edit distance). We applied this general framework to the formalism of process trees as model representation and event logs.

The attached screencast shows the GeneralizedConformance plugin in Prom in action. Currently, it requires two inputs: a Process Tree model, and an Event Log. If you only have an Event Log, you can simply first mine a process tree, as shown in the screencast.

IEEE EDOC 2016 is the twentieth conference in a series that provides the key forum for researchers and practitioners in the field of enterprise computing. EDOC conferences address the full range of models, methodologies, and engineering technologies contributing to intra- and inter-enterprise application systems. Since 1997, EDOC has brought together leading computer scientists, IT decision makers, enterprise architects, solution designers, and practitioners to discuss enterprise computing challenges, models and solutions from the perspectives of academia, industry, and government. The EDOC conference series emphasizes a holistic view on enterprise applications engineering and management, fostering integrated approaches that address and relate business models, business processes, people and technology.

EDOC 2016 welcomes high quality scientific submissions as well as experience papers on enterprise computing from industry. The main theme of EDOC 2016 is ”Enabling innovative business models in the enterprise of the future” and seeks to explore innovative approaches synthesizing concepts of (1) data science, (2) enterprise computing and (3) social computing.

Expert panel discussions and keynotes will address current topics and issues in this domain.

Abstract:

Companies need to efficiently manage their business processes to deliver products and services in time. Therefore, they monitor the progress of individual cases to be able to timely detect undesired deviations and to react accordingly. For example, companies can decide to speed up process execution by raising alerts or by using additional resources, which increases the chance that a certain deadline or service level agreement can be met. Central to such process control is accurate prediction of the remaining time of a case and the estimation of the risk of missing a deadline.

To achieve this goal, we use a specific kind of stochastic Petri nets that can capture arbitrary duration distributions. Thereby, we are able to achieve higher prediction accuracy than related approaches. Further, we evaluate the approach in comparison to state of the art approaches and show the potential of exploiting a so far untapped source of information: the elapsed time since the last observed event. Real-world case studies in the financial and logistics domain serve to illustrate and evaluate the approach presented.

 

 

BPM paper accepted

My paper with Gjergji Kasneci on Temporal Anomaly Detection in Business Processes has been accepted to BPM 2014.

The paper describes an approach to detect anomalies in the timestamps of events that happen during process execution. The approach is based on historical observations of usual behavior and uses a stochastic model to find outliers in a non-parametric way. It helps process analysts to identify and filter errors from process logs, and also to distinguish between measurement errors (where only one timestamp is the outlier) and real delays (where succeeding activities are also shifted).

Paper Abstract:

The analysis of business processes is often challenging not only because of intricate dependencies between process activities but also because of various sources of faults within the activities. The automated detection of potential business process anomalies could immensely help business analysts and other process participants detect and understand the causes of process errors.
This work focuses on temporal anomalies, i.e., anomalies concerning the runtime of activities within a process. To detect such anomalies, we propose a Bayesian model that can be directly inferred form the Petri net representation of a business process. Probabilistic inference on the above model allows the detection of non-obvious and interdependent temporal anomalies.
