(DE) Die Professur Delfmann bietet Abschlussarbeiten im technischen und operativen Bereich des Business Process Management und der Kommunikationssysteme an. Bitte beachten Sie: Auf Grund der formalen und technischen Ausrichtung der Abschlussarbeiten sind sehr gute Kenntnisse im Bereich Algorithmen und Datenstrukturen, Modellierung und Programmierung, Graphentheorie sowie anderer verwandter Disziplinen der Informatik zwingend erforderlich. Folgende Themen sind im Moment möglich.

(EN) The FG Delfmann offers theses in the technical and operative area of Business Process Management and of communication systems. Please note: Due to the formal and technical scope of the topics, excellent (sehr gut) knowledge in the areas of algorithms and data-structures, modeling and programming, graph theorie as well as other disciplines related to computer science are a mandatory requirement. The following topics are currently available.



Nachdem ein Thema in Absprache mit den Betreuern gefunden wurde, umreißt der Studierende in einem Exposé das gewählte Thema und die Vorgehensweise der Abschlussarbeit. Dabei soll auf die Fragestellung, die Zielesetzung, die anzuwendende Methodik sowie den Aufbau der Arbeit eingegangen werden. Ein weiterer Punkt ist ein Zeitplan, der die Schritte der Abschlussarbeit und deren voraussichtliche zeitliche Umsetzung beinhaltet. Die Abgabe findet digital statt. Wird das Exposé akzeptiert, ist der Studierende angenommen und kann mit der Arbeit an der Abschlussarbeit beginnen. Ein Vorlage für ein Exposé finden Sie in der folgenden Sektion.

(EN) After the student and the supervisors agreed on a topic, the student outlines the topic and the procedure of the thesis in an exposé. This should include the problem, the goal, the applied methodology, and the structure of the thesis. Thus, a time line with all steps of the thesis and the expected time of execution must be part of the exposé. The submission will be done digitally. Once the exposé is accepted, the student is accepted and can start working on the thesis. A template can be found in the following section.

  • Mining (FCL-)Rules from Text (Implementation) [BSc/MSc] (reserved)
    Having business rules stored in logical form poses many advantages for companies. However, there are often experts missing to initially create such logical expressions. This thesis should aim at implementing a miner, capable of parsing some form of textual rules into a logic program rule base.

  • Survey of Compliance-Violation-Pattern Classifications [BSc/MSc]
    Many different "categories" of compliance violation patterns have been proposed. This thesis should aim at an extensive review and classification of proposed families of patterns.

  • Mapping possibilities of graph-based and logic-based model query languages (reserved)
    Model query languages are used to find sections in conceptual models that comply with a specific structure or behavior. For instance, in Business Process Management endeavors, we can use those query languages to find weaknesses, inefficiencies or law violations in process models so we can improve them subsequently. Some query languages come from the field of logic, some others come from the field of graph theory. Both have their advantages and disadvantages. In order to exploit the advantages from both fields and develop query languages that include these advantages, we must analyze which capabilities of logic-based languages are already reproducible by graph-based query languages and vice-versa. The latter is the topic of the thesis.
  • Survey of Business-Rule Vendors and Services [BSc/MSc] (reserved)
    Many vendors and services that provide (international) rule bases have emerged, e.g. rule bases containing relevant laws that banks have to adhere to. This thesis should aim at an extensive review, comparison and description of available vendors and services.
  • Survey of quantitative measures of compliance in process models [BSc/MSc]
    Detecting compliance of business processes is a central field of interest. Here, many approaches have been proposed towards finding the presence of errors in process models (e.g. the process as it is modelled violates a law). There has been recent attention towards analyzing the detected errors and comparing them. The intuition behind this is, that different errors may have a different "degree" of violating compliance, i.e. some errors can be said to be "worse/more significant" than others. This thesis should be aimed at an extensive review of proposed quantitative measures, capable of quantitatively assessing the degree/severity of compliance violations.
  • Survey of Process Modeling Recommender Systems (reserved)
    Recommender Systems help process modelers in creating process models more quickly and accurately. Based on the lastly modeled elements, such systems provide suggestions what to model next or point to possible semantic flaws. These systems rely on different methodologies, e.g., ontologies or frequencies of already modeled elements in other models. The thesis should provide an overview of existing recommender systems approaches and the basic formal concepts they rely on.
