基于不确定事件威胁度评估的UUV任务重规划

open access: yes智能科学与技术学报, 2022
无人水下航行器(UUV)的任务规划直接关系到水下作业的效率。由于水下环境复杂,不确定事件频发,有时UUV按照最初的规划很难完成任务。针对UUV任务规划问题,提出基于不确定事件威胁度评估的UUV任务重规划策略。首先,UUV根据任务点的分布进行初始任务规划,采用自组织网络算法为UUV规划访问多任务点的时间顺序及访问任务点的最短路径。其次,判断 UUV 执行任务过程中出现的不确定事件类型,并转换为贝叶斯网络的形式。最后,利用贝叶斯网络对不确定事件的威胁度进行评估。如果威胁度大于阈值,则 UUV 进行任务重规划;
