Li, Shijie (author), Liu, Jialun (author), Negenborn, R.R. (author), Ma, Feng (author)Ship collision is the main type of maritime accidents, which causes great losses on human lives and economy, and brings negative impacts to the maritime environment. In crowded waters such as the sea area near a seaport, multiple ships encountering situations happen frequently. While several methods have been proposed for solving multiple...journal article 2019

Jonker, Tim (author), Duinkerken, M.B. (author), Yorke-Smith, N. (author), de Waal, A. (author), Negenborn, R.R. (author)Increasing international maritime transport drives the need for efficient container terminals. The speed at which containers can be processed through a terminal is an important performance indicator. In particular, the productivity of the quay cranes (QCs) determines the performance of a container terminal; hence QC scheduling has received...journal article 2019

Wang, L. (author), Wu, Qing (author), Liu, Jialun (author), Li, Shijie (author), Negenborn, R.R. (author)At present, with the development of waterborne transport vehicles, research on ship faces a new round of challenges in terms of intelligence and autonomy. The concept of maritime autonomous surface ships (MASS) has been put forward by the International Maritime Organization in 2017, in which MASS become the new focus of the waterborne...journal article 2019

Xie, S. (author), Garofano, V. (author), Chu, Xiumin (author), Negenborn, R.R. (author)Real-time collision avoidance with full consideration of ship maneuverability, collision risks and International Regulations for Preventing Collisions at Sea (COLREGs) is difficult in multi-ship encounters. To deal with this problem, a novel method is proposed based on model predictive control (MPC), an improved Q-learning beetle swarm...journal article 2019

Liu, Chenguang (author), Zheng, Huarong (author), Negenborn, R.R. (author), Chu, Xiumin (author), Xie, Shuo (author)Since vessel dynamics could vary during maneuvering because of load changes, speed changing, environmental disturbances, aging of mechanism, etc., the performance of model-based path following control may be degraded if the controller uses the same motion model all the time. This article proposes an adaptive path following control method...journal article 2019

Wang, L. (author), Wu, Qing (author), Liu, Jialun (author), Li, Shijie (author), Negenborn, R.R. (author)Intelligent motion control is one of the key technologies of ships. This paper studies the application of Adaptive Mutation Beetle Particle Swarm (AMBPS)-PID algorithm in ship motion control. Firstly, the ship MMG model is established. Then the BAS algorithm is introduced, and AMBPS algorithm is improved and designed on this basis. Secondly,...journal article 2019

Wang, K. (author), Yan, Xinping (author), Yuan, Yupeng (author), Jiang, X. (author), Lin, X. (author), Negenborn, R.R. (author)Nowadays, optimization of ship energy efficiency attracts increasing attention in order to meet the requirement for energy conservation and emission reduction. Ship operation energy efficiency is significantly influenced by environmental factors such as wind speed and direction, water speed and depth. Owing to inherent time-variety and...journal article 2018

Lin, X. (author), Negenborn, R.R. (author), Lodewijks, G. (author)Modern technologies have enabled approaches to estimate freshness of perishable products during production and distribution. This allows supply chains to apply more advanced decision support systems in order to further reduce the loss of perishable products. In this paper we focus on the postharvest scheduling of starch potatoes. In...journal article 2018

Alves Beirigo, B. (author), Schulte, F. (author), Negenborn, R.R. (author)Autonomous vehicles (AVs) are expected to widely re-define mobility in the future, transforming many solutions into autonomous services. Nonetheless, this development requires an expected transition phase of several decades in which some regions will provide sufficient infrastructure for AV movements, while others will not support AVs yet. In...conference paper 2018

Ferranti, L. (author), Negenborn, R.R. (author), Keviczky, T. (author), Alonso-Mora, J. (author)This work presents a method for multi-robot trajectory planning and coordination based on nonlinear model predictive control (NMPC). In contrast to centralized approaches, we consider the distributed case where each robot has an on-board computation unit to solve a local NMPC problem and can communicate with other robots in its neighborhood. We...conference paper 2018

This paper focuses on a part of the cut rose supply chain, from auction house to several end customers. A new business mode is considered that would allow end customers to subscribe to florists and have a continuous supply of...journal article 2018
