PhD scholarship in Optimization of Operations in Public Transport

jobbeskrivelse:

A 3-year PhD position in Operations Research is vacant at DTU Management Engineering. The PhD project is financed by the Innovation Fund Denmark and by DTU and will be carried out in collaboration with our industrial collaborators Movia (Danish transport agency) and DSB (Danish State Railways) among others.

Responsibilities and tasks The PhD project is part of a larger project (IPTOP) concerning integrated optimization and planning in public transport. 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 that 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 create operational plans for physical resources and crew given a timetable. The study is expected to develop models and methods to optimize railway operation considering operational constraints, such as rolling stock restrictions, turnaround time and staff restrictions. Integrated vehicle and crew scheduling for bus transportation is already an established research field. For rail transportation, the existing research focuses either on rolling stock circulation, or on crew planning separately while little research has been done towards integrating the two optimization problems. The research will thus be to 1) develop new models for integrated vehicle and crew planning for both bus and railway operations (taking into account constraints faced by local operators to make plans realistic), 2) develop fast algorithms (metaheuristics) for solving the large scale 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 algorithms for constructing timetables.

The PhD project will be carried out under the supervision of Professor Stefan Røpke. Assistant Professor Roberto Roberti and/or Associate Professor Allan Larsen are expected to have a role as co-supervisor.

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 Professor Stefan Ropke, DTU Management Engineering and Associate Professor Allan Larsen, DTU Transport.
