Dr Andrea Raith
BSc, Dipl.-Math., PhD
Andrea Raith is Senior Lecturer in the Department of Engineering Science. She obtained her PhD in Engineering Science in 2010. Her thesis is titled ‘Multi-objective Transportation and Routing Problems’. Prior to this she obtained the degrees of Dipl.-Math. and Bachelor of Science in Mathematics from the Technische Universität Darmstadt, Germany, in 2002 and the degree of Diplom Mathematikerin (similar to MSc) in 2005. As part of her MSc, she wrote a thesis titled ‘Bicriteria optimisation of synchronous generators for wind power plants’ in collaboration with the Department of Electrical Engineering and Information Technology. After the completion of her thesis, she continued working at the department and developed an extension of the bicriteria optimisation method to the multi-objective case. This was used in consulting work for a major manufacturer of wind power plants.
Andrea's main research interests are algorithms for bi- and multiobjective network optimisation problems such as the shortest path problem, network flow problems, and the transportation problem. Furthermore, Andrea currently applies bi-objective optimisation in the context of the so-called traffic assignment problem, which models the route choice of network users in traffic networks. These techniques can be applied to transportation planning, and especially when modelling the effects of road tolling, or when modelling the route choice of cyclists that seek short but comfortable routes. Other interests in transport modelling are modelling of aircraft paths and dealing with weather uncertainty in this context.
More recently, Andrea is exploring the use of Operations Research techniques in health care planning, in particular in radiation therapy treatment.
