Pourmohammadzia, N. (author), Schulte, F. (author), González-Ramírez, Rosa G. (author), Voß, Stefan (author), Negenborn, R.R. (author)Modern ports face significant challenges as strategic nodes of global supply chains, being responsible for the coordination of inbound and outbound flows at deep-sea and in hinterland transport corridors. Digitization and the adoption of disruptive technologies can help ports to tide over operational challenges. Automated Ground Vehicles ...journal article 2023

He, P. (author), Jin, Jian Gang (author), Schulte, F. (author), Trépanier, Martin (author)Travel to intercity transportation hubs, such as railway stations and airports, can be the most troublesome and inefficient part of the entire air/railway travel journey, as travelers often carry large luggage and have stringent arrival time requirements. Taking public transportation, such as metro and bus services, is inconvenient to carry...journal article 2023

Wenzel, P.A. (author), Jovanovic, Raka (author), Schulte, F. (author)Ensuring the accuracy of the estimated time of arrival (ETA) information for ships approaching ports and inland terminals is increasingly critical today. Waterway transportation plays a vital role in freight transportation and has a significant ecological impact. Improving the accuracy of ETA predictions can enhance the reliability of inland...conference paper 2023

Tang, X. (author), Schulte, F. (author)Storage space management in bulk terminals has become an important focus for research and practical operation due to the increasing demand for bulk cargo and limited storage space in stockyards. The study of storage space management in dry bulk terminals is less thorough and comprehensive, and the existing research investigates the storage...conference paper 2023

Kortekaas, Joris J.A. (author), Beirigo, Breno A. (author), Schulte, F. (author)A Dynamically Configurable Autonomous Vehicle (DCAV) is a new class of autonomous vehicle concept using a separable design of lower and upper parts—carriers and modules—to allow more flexible operation. A fleet of DCAVs consists of a set of carriers and a set of compatible modules. Different, possibly crowd-sourced, modules can increase the...conference paper 2023

Xin, Jianbin (author), Meng, Chuang (author), D'Ariano, Andrea (author), Schulte, F. (author), Peng, Jinzhu (author), Negenborn, R.R. (author)This paper investigates a novel routing problem of a multi-robot station in a manufacturing cell. In the existing literature, the objective is to minimize the cycle time or energy consumption separately. The routing problem considered in this paper aims to reduce the cycle time and energy consumption jointly for each robot while avoiding...journal article 2023

Pauwels, A.J. (author), Pourmohammadzia, N. (author), Schulte, F. (author)Next to environmental aspects, establishing areas for safe and economically viable automated driving in mixed-traffic settings is one major challenge for sustainable development of Autonomous Vehicles (AVs). This work investigates safety in the interactions between AVs, human-driven vehicles, and vulnerable road users, including cyclists and...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

Alves Beirigo, B. (author), Schulte, F. (author), Negenborn, R.R. (author)Current mobility services cannot compete on equal terms with self-owned mobility products concerning service quality. Because of supply and demand imbalances, ridesharing users invariably experience delays, price surges, and rejections. Traditional approaches often fail to respond to demand fluctuations adequately because service levels are,...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

Los, J. (author), Schulte, F. (author), Spaan, M.T.J. (author), Negenborn, R.R. (author)The trends of autonomous transportation and mobility on demand in line with large numbers of requests increasingly call for decentralized vehicle routing optimization. Multi-agent systems (MASs) allow to model fully autonomous decentralized decision making, but are rarely considered in current decision support approaches. We propose a multi...conference paper 2022

Los, J. (author), Schulte, F. (author), Spaan, M.T.J. (author), Negenborn, R.R. (author)Collaboration in transportation is important to reduce costs and emissions, but carriers may have incentives to bid strategically in decentralized auction systems. We investigate what the effect of the auction strategy is on the possible cheating benefits in a dynamic context, such that we can recommend a method with lower chances for...conference paper 2022

Lyu, X. (author), Schulte, F. (author)Berth allocation is fundamental to port-related operations in maritime shipping. Port managers have to deal with the increasing demands either by expanding the terminals or by improving efficiency to maintain competitiveness. Port expansion is a long-term project, and it requires much capital investment. Thus, the question of how to enhance...conference paper 2022

Lyu, X. (author), Negenborn, R.R. (author), Shi, Xiaoning (author), Schulte, F. (author)Traditionally, terminal operators create an initial berthing plan before the arrival of incoming vessels. This plan involves decisions on when and where to load or discharge containers for the calling vessels. However, disruptive unforeseen events (i.e., arrival delays, equipment breakdowns, tides, or extreme weather) interfere with the...journal article 2022

Niu, Y. (author), Schulte, F. (author), Negenborn, R.R. (author)Human aspects in collaboration of humans and robots, as common in warehousing, are considered increasingly important objectives in operations management.

Grassel, Joshua (author), Keller, Alfred Craig (author), Hill, Alessandro (author), Schulte, F. (author)The craft beer supply chain in the USA differs from the supply chain of macro breweries in its structure, handled volumes and product shelf-life. In this work, we study how these smaller craft breweries can benefit from transparency in their supply chain. We consider additional information sharing of orders and inventories at downstream nodes...book chapter 2021
