Natalia Kliewer, Clemens Wickboldt
The research project focuses on the evaluation of Data Analytics and Decentralized Ledger Technologies (DLT) / Blockchain methods to address information asymmetries and inefficiencies in business processes for the use of spare parts. The evaluation is carried out from the perspective of a ...
E-Mobility in Public Transportation
Natalia Kliewer, Nils Olsen
In the course of climate change and the proceeding rejection of fossil energy sources towards renewable energies the importance of alternative engines in the transport sector has increased strongly. Electro mobility occupies a special position in the scope of alternative engines because electric ...
Fairness aspects in personnel scheduling
Lena Wolbeck, Natalia Kliewer
Companies with 24/7 service are facing the big challenge of finding duty rosters. Besides cost minimization, employees’ preferences are considered more and more within the planning process. In line with this trend, the aim of this project is to develop a method for solving a staff ...
Strategic Timetable Optimisation to Increase the Expected Punctuality in Rail Transport
Natalia Kliewer, Florian Hauck, in Kooperation mit DB Netz AG
The aim of the project is to minimise the unpunctuality in rail transport resulting from systematic deviations of actual from planned travel times by adjusting planned arrival and departure times using evolutionary or nature-analogue methods. The existing connections and frequencies are to be ...
Airline Revenue Management
In revenue management, methods of quantitatively oriented information systems are used for achieving maximum revenue. For this purpose, those customers with the highest expected willingness to pay receive preferential treatment. This concept is used successfully, especially in airline and ...

New Perspectives on Flight Booking Data
Sebastian Vock, Laurie Anne Garrow
New Perspectives on Airline Booking Data In cooperation with Laurie Garrow (Georgia Institute of Technology), Sebastian Vock currently develop new, data-driven perspectives on airline booking data. By comparing booking distributions from itineraries offered at different times, for ...
Optimization of the course planning - time and space plans
Within the project "Optimization of the course scheduling" a software module is developed with which improved curriculums for the Department of Economics can be created. The module consists of three main components: user interface, database, and optimization. The control of the system and the ...
Natalia Kliewer, in Kooperation mit Charité - Klinik für Psychiatrie und Psychotherapie
The flat-rate payment system for psychiatry and psychosomatics “ Pauschalierende Entgelte für Psychiatrie und Psychosomatik for psychiatry and psychosomatics (PEPP)" will lead to extensive changes in the remuneration of psychiatric-medical services, with consequences for future billing systems that are difficult to predict and the resulting economic implications.
Resources scheduling with irregular timetables
In the research project mathematical optimization models and methods are developed with which the scheduling of mostly regular vehicle blocks and crew duties in public transport (PT) are supported. Although the use of traditional optimization methods leads to optimal but under certain ...
Robust efficiency in Airline Resource Schedules
The project deals with the robust and cost-efficient scheduling of aircraft and crews in the airline industry. Novel mathematical models and optimization techniques shall be developed in order to construct airline resource schedules that are not only cost-efficient but also stable and flexible ...
Robust scheduling in public transport
The research project deals with vehicle and crew scheduling in public bus transport. The goal is the development of robust scheduling approaches so that vehicle blocks and crew duties are less affected by disruptions and short-term changes on the day of operations. Focus of the project is ...
