Publikation Sequenzbildung in der Automobilmontage anhand von materialorientierten Nivellierungsstrategien. Analyse der Auswirkungen auf die innerbetriebliche Materialversorgung(Cuvillier Verlag, 2014) Wörner, DominikSchwankende Bedarfsmengen bei der Materialversorgung in der Endmontage der Automobilindustrie führen zu einem erhöhten logistischen Ressourcenbedarf. Um diesen zusätzlichen Bedarf zu reduzieren, wurde das Konzept der materialorientierten Nivellierung entwickelt. Jedoch führt der Einsatz einer materialorientierten Nivellierung nicht zwangsweise zu einer Reduktion von logistischen Ressourcen. In der vorliegenden Arbeit werden die Zusammenhänge zwischen den Bedarfsmengen und der innerbetrieblichen Materialversorgung dargestellt sowie anhand eines simulativen Bewertungsmodells untersucht. Weiterhin werden Rahmenbedingungen für den erfolgreichen Einsatz einer materialorienterten Nivellierung identifiziert, um den Ressourceneinsatz der innerbetrieblichen Materialversorgung zu reduzieren. Anhand eines Anwendungsbeispiels werden schließlich die Potentiale einer materialorienterten Nivellierung für einen Automobilhersteller bestimmt.02 - MonographiePublikation How to support customer segmentation with useful cluster descriptions(Springer, 2015) Witschel, Hans Friedrich; Loo, Simon; Riesen, Kaspar; Perner, PetraCustomer or market segmentation is an important instrument for the optimisation of marketing strategies and product portfolios. Clustering is a popular data mining technique used to support such segmentation – it groups customers into segments that share certain demographic or behavioural characteristics. In this research, we explore several automatic approaches which support an important task that starts after the actual clustering, namely capturing and labeling the “essence” of segments. We conducted an empirical study by implementing several of these approaches, applying them to a data set of customer representations and studying the way our study participants interacted with the resulting cluster representations. Major goal of the present paper is to find out which approaches exhibit the greatest ease of understanding on the one hand and which of them lead to the most correct interpretation of cluster essence on the other hand. Our results indicate that using a learned decision tree model as a cluster representation provides both good ease of understanding and correctness of drawn conclusions.04B - Beitrag KonferenzschriftPublikation A semantically-enhanced modelling environment for business process as a service(IEEE, 2017) Hinkelmann, Knut; Kurjakovic, Sabrina; Lammel, Benjamin; Laurenzi, Emanuele; Woitsch, Robert; Li, Gang; Yu, YaleIn this paper we present a hybrid modeling approach which supports the continuous alignment of business and IT in the cloud. Business Process as a Service provides the end-to-end cloud support for business processes instead of single applications. A graphical modelling environment allows non-technical modelers to design business processes and to specify requirements in human-interpretable way. Via semantic lifting, the graphical models can be annotated with classes and values from an enterprise ontology. The BPaaS Ontology contains the relevant classes for the smart Business and IT-Cloud alignment. It supports the modeler in using a standard terminology and thus ensures consistent modeling.

Digitalisierung im Vertrieb an Konsumenten. Eine qualitative Studie aus Sicht der Anbieter(Institut für Wirtschaftsinformatik, Hochschule für Wirtschaft FHNW, 2019) Wölfle, Ralf; Leimstoll, UweDie elfte Ausgabe der Studienreihe E-Commerce Report Schweiz behandelt neben der jüngsten Marktentwicklung die strukturellen Veränderungen in der Distribution von Konsumgütern. Das Vertiefungsthema 2019 ist ein Ausblick auf die vernetzte Angebotswelt im Jahr 2025.05 - Forschungs- oder ArbeitsberichtPublikation Real World Data - Technologies, Research Questions and Applications - Study in Cooperation - School of Business & School of Life Science(Fachhochschule Nordwestschweiz FHNW, 2019) Grimberg, Frank; Asprion, Petra; Schneider, Bettina; Miho, Enkelejda; Babrak, Lmar; Habbabeh, AliIn this research report of the University of Applied Sciences and Arts Northwestern Switzerland (FHNW), a classification of ‘Real World Data’ into the research landscape takes place. In addition, an identification of the still open research questions is done based on the fundamental principles and properties. The manifold potential of this relatively new data set is illustrated by a presentation of the already existing but also conceivable future application possibilities. Finally, the contribution of the FHNW, based on its specific competencies, to the further application of the dataset is shown.05 - Forschungs- oder ArbeitsberichtPublikation Checking the students aptitude for a bachelor program: experiences with a web-based tool(2018) Jüngling, Stephan; Telesko, Rainer; Reber, AndreasResearch Abstract: Checking the student’s aptitude for a Bachelor program: Experiences with a Web-based tool Research Objectives: In autumn 2014 the Bachelor program „Business Information Technology (BIT)” has been launched. BIT is about the application of information technology in business with the focus on building information systems. Since several terms, it can be observed that a considerable number of students faces difficulties in modules related to programming and mathematics at the beginning of the study. In order to monitor the aptitude of the program for beginners a project was launched with the aim to develop a method and a web-tool supporting the self-assessment related to indispensable competencies in the BIT program. Methodology: The aptitude test - built with Google Forms - currently consists of 31 predefined multiple choice questions and calculates an overall aptitude value and single aptitude values for the main categories logical and analytical thinking, understanding algorithms and abstract thinking. The questions are taken from well-established test systems like ELIGO-System, BOMAT, CASA etc. and are typically solved within less than 45 minutes. The students can check their suitability for the study programme by comparing their overall aptitude value with a given threshold. First test runs conducted with the tool confirm the validity of the aptitude test. The future scope will involve more students and deal with an analysis of concrete weaknesses that can be used as input to adapt the settings of programming and mathematics modules.06 - PräsentationPublikation Development of a measurement scale for business process standardization(2018) Wurm, Sebastian; Schmiedel, Theresa; Mendling, Jan; Fleig, ChristianProcess-oriented companies face the dichotomy of process standardization versus process diversity. On the one hand, multinational companies try to realize returns of scale by standardization. On the other hand, markets require businesses to adapt to local needs and government regulations. As of to-day, there is no framework available to measure the degree of process standardization. This is both a problem for companies that want to assess their degree of standardization as well as for research that aims to investigate standardization and its connection with other concepts. In this paper, we address this research gap from the perspective of scale development. We utilize a well-acknowledged method for devising a measurement instrument to specifically and directly measure the degree of standardization in business processes. Various application scenarios and future research areas are pointed out.06 - PräsentationPublikation Sentiment analysis for a swiss gig platform company(2019) Pustulka, Elzbieta; Hanne, ThomasWe work with a Swiss Gig Platform Company to identify innovative solutions which could strengthen its position as a market leader in Switzerland and Europe. The company mediates between employers and employees in short term work contracts via a platform system. We first looked at the business processes and saw that some process parts were not being controlled by the company, which is now being remedied. Second, we analyzed the job reviews which the employers and employees write, and implemented a prototype which can detect negative statements automatically, even if the review is positive overall. We worked with a dataset of 963 job reviews from employers and employees, in German, French and English. The reviews have a star rating (1 to 4 stars), with some discrepancies between the star rating and the text. We scored the reviews manually as negative or other, as negative reviews are important for business improvement. We tested several machine learning methods and a hybrid method from Lexalytics.06 - Präsentation
