During lecture time, we have our Lunchtime Seminar each Tuesday from 12.15-12.45. During this seminars, researchers of the Department or invited guest provide us with insights into their research.
|Assessing and improving the maturity of spare parts supply chains in the mechanical engineering industry
Nowadays, the provision of spare parts and related maintenance, repair and overhaul (MRO) services is a differentiating key factor and important growth sector for manufacturers. Especially in the capital-intensive mechanical engineering industry, companies rely on high-value technical systems in their processes. Hence, failures of machinery and related downtimes lead to losses in production or operations, decreasing customer satisfaction and high costs. Corresponding spare parts supply... more
|How to master the "E" - Tools for Competence Identification, Provision and Preservation in a Digitalized Public Sector
The digitalization of every aspect of life is in full swing and becoming an all-embracing societal phenomenon. Public administrations worldwide, eager to increase their efficiency and effectiveness, are in a change process, induced by the pervasiveness of technological advancements. This development does not only mean the substitution of analogue processes by the integration of information technologies, but first and foremost leads to changing demands on the tasks, roles and competences of... more
|Think Digitization to its End – The Impact and Importance of eGovernment to Public Administration
Whereas digitization offers countless opportunities to individuals as well as to organizations, public administration lacks behind in making use of advanced technologies and applying information management tools. However, as public authorities have recognized the potential of digitization for service delivery and administrative organization their efforts in establishing common digitization strategies, institutions, and electronic service delivery are faced with several challenges. Recent and... more
|Accessible mobile and web applications: concerns regarding their development
In the context of approaches for mobile software development, we present our concerns on the level of accessibility and usability for their interface components. We understand that model-driven development (MDD) and cross-platform mobile development, together, may offer benefits to solve the gap and benefit the development of more accessible mobile applications. This presentation discusses the investigations and trends to include requirements for accessibility in interface components during... more
Large-scale spatial systems, such as river catchments, crowds, or land use systems, are difficult to fully analyze empirically. Geosimulation models are built to enable analyses of these systems. On the one hand, geosimulation models help us to better understand the system, because we can 'experiment' with its parameters. On the other hand, geosimulation models are used to make projections of the potential future development of the system under a set of scenarios. Scenario studies are often... more
|Channel Choice Complications: Exploring the multiplex nature of citizens' channel choice
In spite of massive investment and increased adoption of digital services, citizens continue to use traditional channels to interact with public organizations. The channel choice (CC) field of research tries to understand citizens’ interactions with public authorities to make the interaction more efficient and increase citizen satisfaction. However, most studies have been conducted either as surveys of hypothetical services or in experimental settings, leading to a lack of empirical data... more
|Uniform universities? Output Indicators, Data Capitalism and Steering of Science
The talk describes how commercial companies create operating systems with highly integrated services, which scientists use in every phase of their daily work and which by the way produce data about this work. These data, in turn, are processed by the commercial providers and converted into further products, which are now offered to the science bureaucracy as a tool for recruitment and research planning. The structure and marketing of both the tools for scientists and the controlling tools... more
|Test-Case Generation for Java Programs
Java is still one of the most popular programming languages and widely used to develop enterprise, mobile, and web applications. This talk presents an automated approach to generate unit tests for Java programs. The approach is based on symbolic execution, a popular program analysis technique that is able to explore all execution paths through a program.
|The value of practical and academic partnering – the case of ERCIS & Arvato/Bertelsmann
While digitization and digitalization require substantial organic change (1) and often times M&A (2), partnering represents a 3rd lever for strategy execution. Partners can come from multiple backgrounds. Some working for-profit, such as software vendors, consultants or incubators. Yet there are interesting players from the non-profit arena, such as governmental institutions or universities. Universities among others focus on education but also on research that ideally... more
|Artificial Intelligence is a trending topic in computer science
Autonomous systems rely on AI to make decisions and adapt to changes. What role do security considerations play when designing such systems? This talk will give an overview of the interaction and combination of IT security with artificial intelligence.
