PhD scholarship in Optimization of Public Transport Schedules

jobbeskrivelse:
A 3-year PhD position in Operations Research is vacant at DTU Transport. The PhD project is financed by the Innovation Fund Denmark and by DTU and will be carried out in collaboration with our industrial collaborators, namely, Movia (Danish transport agency), DSB (Danish State Railways), BaneDenmark and Trafikstyrelsen. Responsibilities and Tasks The PhD project is part of a larger project Integrated Public Transport Optimization and Planning (IPTOP). The goal of the overall project is to develop methods for planning public transport that integrates and synchronizes timetables across different modes of transportation (i.e., bus and rail). The overall project aims at producing timetables that provide a better level of service for the passengers. However limited resources are available to carry out the timetables, so it is important to be able to evaluate a timetable from a resource point of view. For bus timetables, it is necessary to know how many buses and drivers will be needed to carry out the plan; for train timetables, it is necessary to know if the timetable is feasible at all given the restrictions of track capacity and secondary what the costs are in terms of rolling stock and crew requirements. More information about the overall project is available at http://www.iptop.transport.dtu.dk/. The aim of the PhD project is to optimize the schedules of both trains and buses given the expected passengers flows and preferences. Such schedules are expected to be properly integrated in order to decrease the passenger transfer times. The project will start from recent studies illustrating the benefits of optimal route design, stop locations, and overall passenger railway optimization in real-size public transport networks, and from the state-of-the-art mathematical algorithms (e.g., column generation, cutting planes, parallel heuristics, etc). Different timetabling principles will also be investigated. The research will thus be aimed at 1) develop new models for integrated optimized timetables for both bus and railway operations, 2) develop fast algorithms (metaheuristics) for solving the large-scale problems and exact algorithms for small/medium-sized problems. The precise scope and goals of the PhD project will be settled with the PhD candidate. The candidate is expected to work closely together with the research team that is developing optimization algorithms for operations in public transport. The PhD project will be carried out under the supervision of Associate Professor Allan Larsen. Professor Stefan Røpke, from DTU Management Engineering, and/or Assistant Professor Roberto Roberti, from DTU Transport, are expected to have a role as co-supervisor(s). The applicant is expected to contribute to teaching at the department and must take courses equivalent to 30 ECTS points during the studies. Qualifications The applicant should have a strong background in operations research or related subjects (i.e., computer science or mathematics). This background must be documented by courses, MSc / BSc theses and/or publications. Good English skills are expected. Relevant programming experience in a programming language, such as C, C++, C#, and/or Java, is required. Approval and Enrollment The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide. Assessment The assessment of the applicants will be made by Associate Professor Allan Larsen, DTU Transport and Professor Stefan Røpke, DTU Management Engineering.
