Maestre, José M. (author), Velarde, Pablo (author), Ishii, Hideaki (author), Negenborn, R.R. (author)In this paper, we present an analysis of the vulnerability of a distributed model predictive control (DMPC) scheme in the context of cyber-security. We consider different types of the so-called insider attacks. In particular, we consider the situation where one of the local controllers sends false information to others to manipulate costs for...journal article 2021

Guo, W. (author), Atasoy, B. (author), Beelaerts van Blokland, W.W.A. (author), Negenborn, R.R. (author)This paper investigates a dynamic and stochastic shipment matching problem, in which a platform aims to provide online decisions on accepting or rejecting newly received shipment requests and decisions on shipment-to-service matches in global synchromodal transportation. The problem is considered dynamic since the platform receives requests...journal article 2021

Li, M. (author), Jiang, X. (author), Negenborn, R.R. (author)Operation & maintenance (O&M) costs account for a large portion of total life cycle cost for onshore wind energy, and the amount is estimated to be more for offshore wind energy. Developing a sound opportunistic maintenance strategy is a solution to reduce O&M costs and enhance wind energy's competitiveness. When the wind farm is...journal article 2021

(author), Sun, Peiting (author), Negenborn, R.R. (author), Yan, Xinping (author)It is of significant importance to optimize the energy consumption of ships in order to improve economy and reduce CO<sub>2</sub> emissions. However, the energy use of ships is affected by a series of navigational environmental parameters, which have certain spatial and temporal differences and variability. Therefore, the dynamic...journal article 2021

Haseltalab, A. (author), van Biert, L. (author), Sapra, H.D. (author), Mestemaker, Benny (author), Negenborn, R.R. (author)The shipping industry is facing increasing demands to reduce its environmental footprints. This has resulted in adoption of new and more environmental friendly power sources and fuels for on-board power generation. One of these novel power sources is the Solid Oxide Fuel Cell (SOFC) which has a great potential to act as a power source, thanks...journal article 2021

Guo, W. (author), Atasoy, B. (author), Beelaerts van Blokland, W.W.A. (author), Negenborn, R.R. (author)This paper investigates a dynamic and stochastic shipment matching problem faced by network operators in hinterland synchromodal transportation. We consider a platform that receives contractual and spot shipment requests from shippers, and receives multimodal services from carriers. The platform aims to provide optimal matches between...journal article 2021

Larsen, R.B. (author), Baksteen, Ruud (author), Atasoy, B. (author), Negenborn, R.R. (author)Container transport requires real-time control and a high degree of cooperation to alleviate disturbances and perform smoothly without unnecessary environmental impact and monetary losses. The involved operators are, however, often reluctant to cooperate as they fear loosing valuable information and autonomy, eventually leading their clients...journal article 2021

Larsen, R.B. (author), Sprokkereef, Jasper M. (author), Atasoy, B. (author), Negenborn, R.R. (author)It is desirable to improve the efficiency of container transport both from an economical and an environmental point of view, as increased efficiency decreases costs and emissions per transported container. Modern transport schemes, such as synchromodal transport, use a-modal bookings to increase the flexibility of the transport providers where...conference paper 2021

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
