Electric vehicle-sharing systems have been introduced to the cities to increase mobility, and reduce congestion and pollution. These systems give their users self-service access to vehicles scattered around cities and rent them for short time intervals throughout the day. Carsharing systems contribute to the integration of public transport by filling the gap between the flexibility offered by privately-owned car transportation and fixed-route and -schedule mass public transport services. They have the potential to decrease the car ownership, vehicle kilometres travelled, parking space need, and footprint of personal transport. They are grouped according to the flexibility they offered to their users. In (station-based) one-way systems, users are allowed to return the cars to the available parking spots of any station of the system whereas round-trip systems restrict users to return vehicles to their pick-up stations. In this talk, I am going to cover three different one-way (electric) vehicle-sharing problems that we worked on for different levels of decisions. The first paper covers a strategic-tactical level decision that was used to introduce the flexibility of one-way trips to a round-trip system. The second paper handles an operational planning problem that aims to look for the relationship between the customers’ acceptance level of spatial and temporal flexibility, and the profitability of the system. The third paper deals with a real-time operational application of a vehicle-sharing system and proactive relocation policies based on Markov chain dynamics. I will conclude my talk with a summary of the important contributions so far and some open questions from the research field.



Burak Boyacı is a Senior Lecturer (Associate Professor) in the Management Science Department and has affiliations with the Centre for Transport and Logistics (CENTRAL), Centre for Doctoral Training on Statistics and Operational Research in Partnership with Industry (STOR-i), and Data Science Institute (DSI) at Lancaster University. He has joined Lancaster University Management School in September 2013. He received his BSc and MSci degrees from the Industrial Engineering Department of Boğaziçi University. He received his PhD degree from Ecole Polytechnique Fédéral de Lausanne in 2014. His research and teaching interests include large-scale optimization problems, specifically discrete optimization and column generation applications. He has a particular interest in problems from transportation and logistics, more specifically city logistics, emergency response planning and operations, public and shared-use transport planning, air and freight transportation operations. His current work is focused on carsharing systems, mobility-as-a-service applications, airline maintenance scheduling, operations and maintenance in offshore wind farms, resource constraint project scheduling, and waste routing. He has published in various OR journals and presented in many conferences. In 2017, the article he has co-authored, that is published in the European Journal of Operational Research, received the best paper (in Innovative Applications of OR) award.
