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, 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 ...

PEPPplus

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

Boris Amberg

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 ...
