• Autonomous Machinery Management for Supervisory Risk Control Using Particle Swarm Optimization 

      Blindheim, Simon André Johnsen; Rokseth, Børge; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)
      Safe navigation for maritime autonomous surface ships (MASS) is a challenging task, and generally highly dependent on effective collaboration between multiple sub-systems in environments with various levels of uncertainty. ...
    • Development and testing of a risk-based control system for autonomous ships 

      Johansen, Thomas; Blindheim, Simon André Johnsen; Torben, Tobias Valentin Rye; Utne, Ingrid Bouwer; Johansen, Tor Arne; Sørensen, Asgeir Johan (Journal article; Peer reviewed, 2023)
      This paper presents a method for designing and verifying a control system with risk-based decision-making capabilities to improve its intelligence and enhance the safe operation of autonomous systems. The decision-making ...
    • Identifying clothing articles by use of iterative classification 

      Blindheim, Simon André Johnsen (Master thesis, 2018)
      Supervised machine learning is commonly applied in order to give machines the ability to assign labels to input data. Given a set of categories, the machine is tasked with identifying which class new observations belong ...
    • Particle Swarm Optimization for Dynamic Risk-Aware Path Following for Autonomous Ships 

      Blindheim, Simon André Johnsen; Johansen, Tor Arne (Peer reviewed; Journal article, 2022)
      This work presents the use of particle swarm optimization (PSO) for dynamic risk-aware path following, or waypoint re-planning during autonomous surface navigation in a maritime environment with polygonal grounding obstacles. ...
    • Risk-based supervisory control for autonomous ship navigation 

      Blindheim, Simon André Johnsen; Johansen, Tor Arne; Utne, Ingrid Bouwer (Peer reviewed; Journal article, 2023)
      This paper proposes a novel method to transform the results of qualitative risk analysis into a numeric optimal control problem for autonomous ship navigation. Today, making autonomous high-level decisions replacing a crew ...
    • Ship Collision Avoidance and Anti Grounding Using Parallelized Cost Evaluation in Probabilistic Scenario-Based Model Predictive Control 

      Tengesdal, Trym; Johansen, Tor Arne; Grande, Tom Daniel; Blindheim, Simon André Johnsen (Peer reviewed; Journal article, 2022)
      The ability to effectively process large amounts of information in reasonable time will be important for robust deliberative collision avoidance (COLAV) planning algorithms. Failure to do so can lead to collision, and can ...
