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.

Datesort ascending Title Abstract
04.06.2019 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

28.05.2019 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

21.05.2019 Geosimulation modelling

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

14.05.2019 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

07.05.2019 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

30.04.2019 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

23.04.2019 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

16.04.2019 Increasing Model Utilization in Software Engineering

"Model-Driven Software Development is widely adopted throughout research and industry" is a sentence that often opens scientific papers regarding model-driven software engineering. While it is true that models are widely adopted they are often not utilized to their full extent. Therefore, efficiency enhancement potential and inherent insights remain unused. The talk presents the current status of research on increasing model utilization in software engineering. The audience will understand... more

09.04.2019 Multimodality in Multi-Objective Optimization - More Boon than Bane?

This talk addresses a new perspective on multimodality of multi-objective (MO) optimization landscapes.  In Operations Research, we learn that local optima are traps for local opimizers. Interestingly, this fact is simply transfered to multi-objective optimization as certainty as well, although we do not have enough insights into multi-objective landscape characteristics. In our work, we use sophisticated visualization techniques, which rely on gradient fi eld heatmaps and enable a... more

29.01.2019 Lunchtime Seminar - Towards the automated Design of Heuristic-Based algorithms for lot-sizing problems

Supply chains and production environments, especially in high wage countries like Germany, are constantly becoming more dynamic and complex for several decades already. This development finds its most recent peak in the advent of Industrie 4.0, in which it is intended to enable production systems to be reconfigurable and flexible, manufacturing products in vastly varying amounts and constantly changing specifications. Such changes of course influence the planning model that creates the base... more
