Intelligent Risk-Based Under-Ice Altitude Control for Autonomous Underwater Vehicles

Risk-based path planning for autonomous underwater vehicles in an oil spill environment

“…This application of the BN model identified risk factors from technical, organizational, and operational perspectives, and it quantified the probability of the IMR mission failure. More recently, Bremnes et al (Bremnes et al, 2019;Bremnes et al, 2020) proposed a Bayesian approach towards supervisory risk control of AUVs for under-ice operations. The BN reasoning was employed to predict the risk state for online risk modelling.…”

“…With the development of AUV technologies, risk analysis of AUV operations is broadening to an intelligent scope (Bremnes et al, 2019). Intelligent risk analysis in the AUV domain refers to performing risk analysis and decision making by the vehicle system itself instead of human operators.…”

A copula‐based method of risk prediction for autonomous underwater gliders in dynamic environments

“…Over the years, BBN has been widely applied for risk analyses in the AUV domain. Former applications of the BBN model mainly include estimating the risk of AUV loss (Yang et al., 2020; Bremnes et al., 2019; Brito & Griffiths, 2016) and monitoring the mission abort (Brito & Griffiths, 2018; Hegde et al., 2018; Thieme et al., 2015). There are several advantages of using the BBN to assist in risk analyses.…”
