The Chair of Economics, Discrete Optimization and Mathematics at Friedrich-Alexander-Universitaet Erlangen-Nuernberg (FAU), Germany, invites applications for a full-time     PhD Position in Discrete Optimization at the Department of Mathematics to be filled as soon as possible for an initial period of three years. The successfull applicant will work in a project on the     Integrated Optimization of International Transportation Networks in cooperation with DB Cargo Polska, a subsidiary of Deutsche Bahn AG. The focus of the project will be the development of model hierarchies and exact mixed-integer optimization methods for the optimal allocation of resources in railway transport (staff, rolling stock, ...), especially in the context of border-crossing transport services. The mathematical work in this project will focus on structural analysis of this problem, drawing e.g. upon polyhedral analysis and graph theory, as well as the treatment of data uncertainties, which will require the development of robust or stochastic optimization approaches. The PhD candidate will spend secondments for technical and scientific training at DB Cargo Polska in Zabrze, Poland. The PhD degree will be awarded by FAU. Applicants should have completed their studies at master level in a program with strong mathematical background in discrete optimization. We seek excellent open-minded and team-spirited PhD candidates who will get unique international, interdisciplinary and inter-sectoral training in scientific and transferable skills by distinguished leaders from academia and industry. This position is offered as part of the European Industrial Doctorate (EID) training network ROMSOC (Reduced Order Modelling, Simulation and Optimization of Coupled systems) within the Marie Skłodowska Curie Actions of the Horizon 2020 programme. Please note that according to the EU mobility rule governing this kind of training network, we can only consider applicants who have not lived or worked in Germany for more than 12 months during the last 3 years. Furthermore, we can only consider candidates whose master degree does not date back longer than 2014. For further information and the application guidelines, please see the official announcement: https://euraxess.ec.europa.eu/jobs/294945 Please send your complete application documents (motivation letter, detailed CV, certificates, list of MSc courses and grades, copy of the master thesis, reference letter etc.) in electronic form until 30 April 2018 to: Alexander.Martin@fau.de (Prof. Dr. Alexander Martin FAU Erlangen-Nuernberg Lehrstuhl fuer Wirtschaftsmathematik Cauerstraße 11 91058 Erlangen, Germany)
