Predictive Process Monitoring is becoming more prevalent as an aid for organizations to support their operational processes. However, most software applications available today require extensive technical know-how by the operator and are therefore not suitable for most real-world scenarios. Therefore, this work presents a prototype implementation of a Predictive Process Monitoring dashboard in the form of a web application. The system is based on the PPM Camunda Plugin presented by Bartmann et al. (2021) and allows users to easily create metrics, visualizations to display these metrics, and dashboards in which visualizations can be arranged. A usability test is with test users of different computer skills is conducted to confirm the application’s user-friendliness.
Public electronic procurement (eProcurement), here electronic sourcing (eSourcing) in particular, is almost certainly on the agenda when eGovernment experts meet. Not surprisingly is eProcurement the first high-impact service to be addressed in the European Union- recent Action Plan. This is mainly dedicated to the fact that public procurement makes out almost 20% of Europe- GDP and therefore holds a huge saving potential. To some extent this potential lies in the common European market, since effective cross-boarder eSourcing solutions can open many doors, both for buyers and suppliers. To achieve this, systems and processes and tools, need to be adoptable, transferable as well as be able to communicate with each other. In one word, they need to be interoperable. In many relevant domains, interoperability has reached a very positive level, standards have been established, workflows been put in place. In other domains however, there is still a long road ahead. As a consequence it is crucial to define requirements for such interoperable eSourcing systems and to identify the progress in research and practice.
This thesis explores the possibilities of probabilistic process modelling for the Computer Supported Cooperative Work (CSCW) systems in order to predict the behaviour of the users present in the CSCW system. Toward this objective applicability, advantages, limitations and challenges of probabilistic modelling are excavated in context of CSCW systems. Finally, as a primary goal seven models are created and examined to show the feasibilities of probabilistic process discovery and predictions of the users behaviour in CSCW systems.
Die vorliegende Arbeir zeichnet eine Kategorisierung der im deutschen Fernsehen und Rundfunk vorhandenen Gewinnspiele auf. Beginnend mit der Erläuterung von grundlegenden Begrifflichkeiten und dem Beleuchten der Verfahren zur Teilnehmerauswahl wird der Leser an das Thema der Arbeit herangeführt. Fortgesetzt wird mit der eigentlichen Darstellung der momentan vorhandenen Gewinnspielformate. Abschließend gibt die Arbeit eine erste Festlegung und Aufrechnung einer Gewinnwahrscheinlichkeit an.
The aim of this thesis is to provide the information that is needed to build a correct data history in a Business Intelligence System. Thereby the phenomena of "Slowly Changing Dimensions" is emphasised. At first a definition of business intelligence is provided which includes the ETL-process, data warehousing, and on-line analytic processing. Furthermore data mining, reporting, dashboards an BI-portals can be considered as a part of the BI-process. It is possible to represent slowly changing dimensions in a database management system. This is modelled in the ETL-process. The data is transformed in a certain way, before being loaded into the data warehouse. Type 1 SCD represents a simple update of the current dimension entry. Type 2 SCD provides a history of the data. It saves all the intermediate states of it. Thus, a user can track all states that changed during a certain time. Type 2 SCD is the one which is mostly used. Type 3 SCD provides just the original and the actual state. Aside from this three types there are existing some hybrid and extended versions.
Die vorliegende Arbeit bildet den Abschluss eines Forschungspraktikums von Studierenden der Masterstudiengänge Informationsmanagement und Wirtschaftsinformatik unter Betreuung der wissenschaftlichen Mitarbeiterin Daniela Simić-Draws und von Prof. Dr. Rüdiger Grimm. Eine wesentliche Vorlage zu dieser Arbeit war ein Vorgehensmodell zur Sicherheitsanalyse von Geschäftsprozessen, das von D. Simić-Draws im Rahmen ihrer Dissertation erarbeitet wird und zu dessen laufender Verbesserung dieses studentische Forschungspraktikum wertvolle Hinweise liefern konnte. Als Anwendungsbeispiel wurden die sicherheitskritischen Prozesse "Kommunalwahl" und "Geldauszahlung am Bankautomaten" gewählt, weil die Arbeitsgruppe von Prof. Grimm in diesen beiden Anwendungen aus vorhergehender wissenschaftlicher Arbeit Erfahrung gesammelt hat. Insbesondere zum Anwendungsbeispiel "Kommunalwahl" hatte sich dankenswerterweise das Ordnungsamt Koblenz, das für die Kommunalwahlen zuständig ist, unter aktiver Mithilfe ihres Leiters Dirk Urmersbach zur Zusammenarbeit angeboten, so dass dieser Geschäftsprozess wirklichkeitsnah untersucht werden konnte.
The industry standard Decision Model and Notation (DMN) has enabled a new way for the formalization of business rules since 2015. Here, rules are modeled in so-called decision tables, which are defined by input columns and output columns. Furthermore, decisions are arranged in a graph-like structure (DRD level), which creates dependencies between them. With a given input, the decisions now can be requested by appropriate systems. Thereby, activated rules produce output for future use. However, modeling mistakes produces erroneous models, which can occur in the decision tables as well as at the DRD level. According to the Design Science Research Methodology, this thesis introduces an implementation of a verification prototype for the detection and resolution of these errors while the modeling phase. Therefore, presented basics provide the needed theoretical foundation for the development of the tool. This thesis further presents the architecture of the tool and the implemented verification capabilities. Finally, the created prototype is evaluated.
Diese Bachelorarbeit behandelt die Erweiterung eines Instant Messenger um die Funktion einer verschlüsselten Audio-/Videokonferenz. Es werden verschiedene zu diesem Zweck nutzbare Techniken beschrieben und gegenübergestellt. Besonderer Wert wird darauf gelegt, die Verbindung dementsprechend zu sichern, dass auch vertrauliche Informationen übermittelt werden können. Letztlich wird die Implementierung in Java für den Instant Messenger "Spark" sowie die Integration der Konferenz in ein eVoting-Plugin erläutert.
