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.

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

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

Bouwstra, Pieter S. (author), Correia, Gonçalo (author), Bijl, Peter (author), Negenborn, R.R. (author), Atasoy, B. (author)The quality of the delivery service is a crucial asset for an e-grocer to create and maintain a loyal customer-base. With the rapid market growth of e-grocers over the last decade, there is an urgent need for e-grocer specific routing systems. Although stochastic and dynamic routing models are studied for a wide range of applications, e...conference paper 2021
