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

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

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

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

Dalmijn, Menno (author), Atasoy, B. (author), Bijl, Peter (author), Negenborn, R.R. (author)This paper proposes a model for charge scheduling of electric vehicles in last-mile distribution that takes into account battery degradation. A mixed integer linear programming formulation is proposed that minimizes labor, battery degradation and time-dependent energy costs. The benefit of implementing charge schedule optimization is assessed...conference paper 2020

Zheng, Huarong (author), Jin, Chen (author), Luo, Xiling (author), Negenborn, R.R. (author), Wang, Yuexuan (author)The demand for transport between terminals within port areas, known as inter terminal transport (ITT), is increasing. This paper proposes a dynamic rolling horizon scheduling strategy for ITT using waterborne Autonomous Guided Vessels (waterborne AGVs). The strategy is dynamic in that it can handle the dynamically arriving ITT requests and...conference paper 2020

Pourmohammadzia, N. (author), Schulte, F. (author), Negenborn, R.R. (author)Autonomous vehicles (AVs) have been successfully applied in closed environments such as ports and industrial zones, while their operation in open areas has a long way to go. The current research is initiated to overcome this limitation by the introduction of platooning as a transfer mode. It investigates a container transportation problem...conference paper 2020

Li, Shijie (author), Liu, Jialun (author), Negenborn, R.R. (author), Wu, Qing (author)Autonomous shipping refers to the ability of a ship to independently control its own actions while transporting cargo from one port to another, which places higher requirements on ship motion control methods. When a ship enters a port, it is important to ensure that the ship sails from the fairway area to the assigned position at the berth...journal article 2020

Xin, J. (author), Meng, Chuang (author), Schulte, F. (author), Peng, Jinzhu (author), Liu, Yanhong (author), Negenborn, R.R. (author)This article investigates a new collision-free routing problem of a multirobot system. The objective is to minimize the cycle time of operation tasks for each robot while avoiding collisions. The focus is set on the operation of the end-effector and its connected joint, and the operation is projected onto a circular area on the plane. We...journal article 2020

Los, J. (author), Schulte, F. (author), Spaan, M.T.J. (author), Negenborn, R.R. (author)The transportation market requires collaboration to improve efficiency and reduce emissions. Individual carriers, however, might be hesitant to share their private information on a transportation platform. Although a few articles have investigated the value of information sharing, they assume identical behaviour of all carriers. In practice,...journal article 2020
