Neijmeijer, Nout (author), Schulte, F. (author), Tierney, Kevin (author), Polinder, H. (author), Negenborn, R.R. (author)Dynamic pricing can be used for better fleet distribution in free-floating vehicle sharing (FFVS), and thus increase utilization and revenue for the provider by reducing supply-demand asymmetry. Supply-demand asymmetry refers to the existence of an undersupply of vehicles at some locations at the same time as underutilization of vehicles at...conference paper 2020

Larsen, R.B. (author), Atasoy, B. (author), Negenborn, R.R. (author)When barges are scheduled before the demand for container transport is known, the scheduled departures may match poorly with the realised demands’ due dates and with the truck utilization. Synchromodal transport enables simultaneous planning of container, truck and barge routes at the operational level. Often these decisions are taken by...conference paper 2020

Alves Beirigo, B. (author), Schulte, F. (author), Negenborn, R.R. (author)Residents of cities’ most disadvantaged areas face significant barriers to key life activities, such as employment, education, and healthcare, due to the lack of mobility options. Shared autonomous vehicles (SAVs) create an opportunity to overcome this problem. By learning user demand patterns, SAV providers can improve regional service...conference paper 2020

Los, J. (author), Schulte, F. (author), Gansterer, Margaretha (author), Hartl, Richard F. (author), Spaan, M.T.J. (author), Negenborn, R.R. (author)While collaborative vehicle routing has a significant potential to reduce transportation costs and emissions, current approaches are limited in terms of applicability, unrealistic assumptions, and low scalability. Centralized planning generally assumes full information and full control, which is often unacceptable for individual carriers....conference paper 2020

Pourmohammadzia, N. (author), Schulte, F. (author), Souravlias, D. (author), Negenborn, R.R. (author)Automated ground vehicles (AGVs) are essential parts of container operations at many ports. Forming platoons—as conceptually established in trucking—may allow these vehicles to directly cater demand points such as dry ports in the hinterland. In this work, we aim to assess such AGV platoons in terms of operational efficiency and costs,...conference paper 2020

Zhang, Y. (author), Atasoy, B. (author), Souravlias, D. (author), Negenborn, R.R. (author)Inland waterway transport is becoming attractive due to its minimum environmental impact in comparison with other transportation modes. Fixed timetables and routes are adopted by most barge operators, avoiding the full utilization of the available resources. Therefore a flexible model is adopted to reduce the transportation cost and...conference paper 2020

Boers, Luke (author), Atasoy, B. (author), Correia, Gonçalo (author), Negenborn, R.R. (author)We present a “rich” Petrol Station Replenishment Problem (PSRP) with real-life characteristics that represents the complexities involved in actual operations. The planning is optimised over multiple days and therefore, the new variant can be classified as the Multi-Period Petrol Station Replenishment Problem (MP-PSRP). A Mixed Integer Linear...conference paper 2020

Guo, W. (author), Atasoy, B. (author), Beelaerts van Blokland, W.W.A. (author), Negenborn, R.R. (author)Global intermodal transportation involves the movement of shipments between inland terminals located in different continents by using ships, barges, trains, trucks, or any combination among them through integrated planning at a network level. One of the challenges faced by global operators is the matching of shipment requests with transport...conference paper 2020

Haseltalab, A. (author), Garofano, V. (author), van Pampus, Maurits (author), Negenborn, R.R. (author)The maneuvering control of autonomous vessels has been under extensive investigations by academic and industrial communities since it is one of the primary steps towards enabling unmanned shipping. In this paper, a model predictive control (MPC) approach is presented for trajectory tracking control of vessels which takes into account the...journal article 2020

Meng, Chuang (author), Xin, J. (author), Peng, Jinzhu (author), Negenborn, R.R. (author)In this paper, we study the collision-free routing of a multi-robot system to complete given tasks in the shortest time. In a robotic assembly unit, several stations work serially and in parallel. In a station, multiple robots share the same workspace and face the challenge of minimizing the cycle time and avoiding collisions at the same time...conference paper 2019

Larsen, R.B. (author), Atasoy, B. (author), Negenborn, R.R. (author)When containers are transported on a-modal bookings, the transport supplier can decide which combination of trucks, trains, ships, etc. to use. This gives the flexibility to transport suppliers to route the containers in accordance with the current state of the synchromodal transport network. At the same time, it enables the transport...conference paper 2019

Li, S. (author), Liu, J. (author), Negenborn, R.R. (author)Over the past two decades, a number of methods have been proposed for solving maritime collision avoidance problems. Most of these works take a single ship's perspective and focus on one-to-one or one-to-many situations. To more complicated many-to-many situations, less attention has been paid. To deal with the many-to-many collision...journal article 2019
