Nicolet, A. (author), Negenborn, R.R. (author), Atasoy, B. (author)Understanding the modal split in freight transportation is a key factor for the successful implementation of innovations. Mode choice models should then be as representative of reality as possible. The use of disaggregate shipment data can help to achieve it. However, shipment data are often unavailable due to confidentiality issues. As a result...journal article 2022

Alves Beirigo, B. (author), Negenborn, R.R. (author), Alonso-Mora, J. (author), Schulte, F. (author)With the popularization of transportation network companies (TNCs) (e.g., Uber, Lyft) and the rise of autonomous vehicles (AVs), even major car manufacturers are increasingly considering themselves as autonomous mobility-on-demand (AMoD) providers rather than individual vehicle sellers. However, matching the convenience of owning a vehicle...journal article 2022

Guo, W. (author), Atasoy, B. (author), Negenborn, R.R. (author)Global synchromodal transportation involves the movement of container shipments between inland terminals located in different continents 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 accepted shipments with...journal article 2022

Wang, Le (author), Li, Shijie (author), Liu, Jialun (author), Wu, Qing (author), Negenborn, R.R. (author)Autonomous docking and undocking control is an important part of intelligent ship motion control. In this study, the adaptive-mutation beetle swarm prediction (AMBS-P) algorithm is used to propose a control approach for autonomous docking and undocking. Firstly, this paper introduces the principle of the AMBS-P algorithm, then the convergence...journal article 2022

Los, J. (author), Schulte, F. (author), Gansterer, Margaretha (author), Hartl, Richard F. (author), Spaan, M.T.J. (author), Negenborn, R.R. (author)Carriers can remarkably reduce transportation costs and emissions when they collaborate, for example through a platform. Such gains, however, have only been investigated for relatively small problem instances with low numbers of carriers. We develop auction-based methods for large-scale dynamic collaborative pickup and delivery problems,...journal article 2022

Zhang, Y. (author), Li, X. (author), van Hassel, E.B.H.J. (author), Negenborn, R.R. (author), Atasoy, B. (author)In synchromodal transport, a freight forwarder usually serves multiple shippers with heterogeneous and vague preferences, such as low-cost, fast, or reliable transport. Ignoring shippers’ preferences will negatively impact the satisfaction of shippers and lead to the loss of them in the longer run. In order to incorporate these preferences, a...journal article 2022

You, Xu (author), Yan, Xinping (author), Liu, Jialun (author), Li, Shijie (author), Negenborn, R.R. (author)This paper investigates the formation keeping problem of heterogeneous ships with underactuated inputs, uncertain dynamics, and environmental disturbances. The control objective is to make the heterogeneous followers keep the desired formation while tracking a leader. To solve the problem effectively, a novel virtual leader–follower formation...journal article 2022

Zhang, Y. (author), Atasoy, B. (author), Negenborn, R.R. (author)Decision-makers in synchromodal transport (ST) have different preferences toward different objectives, such as cost, time, and emissions. To solve the conflicts among objectives and obtain preferred solutions, a preference-based multi-objective optimization model is developed. In ST, containers need to be transferred across modes, therefore...journal article 2022
