Autonomous underwater vehicle(AUV)is an effective equipment for ocean development and exploration.It is important to improve the adaptability and reliability of AUV mission execution in consideration of various uncertainties such as complex ocean environment,changeable mission and limited communication.In this paper,we study and design a hierarchical mission planning and re-planning architecture.It is based on hierarchical task network which can describe experiential knowledge and solve problems efficiently.Secondly,we propose the mission planning method based on and-or decomposition tree and task planning scheme based on the finite state machine respectively. These methods achieve the hierarchical re-planning model and handle different uncertainty on different level.Then, the significance of hierarchical mission re-planning is expounded and the supervision and decision-making algorithm for hierarchical mission re-planning is presented.Finally,simulation experiments indicate that the designed hierarchical architecture,mission planning and re-planning supervision and decision-making methods can significantly improve the adaptability and reliability of AUV mission execution.
