Addressing the challenges inherent in passive unmanned search and rescue missions at sea, including difficulties in target identification, broad search areas, and slow route planning, a strategic process was introduced for maritime search and rescue area planning and a route planning model specifically designed for passive unmanned missions. By thoroughly understanding the emergency response operations at sea and the specific needs for route planning, an optimal routing model have been developed considering factors such as the efficiency of search and rescue area coverage and the cost of rescue routes. The objective function is constructed within these constraints and solved using the whale optimization algorithm. The validity of the model is confirmed through designated scenario experiments, indicating that our proposed model for maritime passive unmanned search and rescue route planning is capable of swiftly identifying the search and rescue area and efficiently discovering a route with reduced costs.
对比文献[23][24]的技术思路,进行相关实验设计,文献[23]中对海上搜救问题,将搜救海域划分为若干小段,并采用平行线样式的航路规划对小段中区域进行覆盖搜索。此方案为经典的搜索规划方案,为保证对比实验的合理性,对其矩形小段近似为无人艇搜索圆形区域的外接正方形,其长度为16 n mile,暂不考虑搜救线路转向时间,将其划分的航路规划小段数量依据搜救任务点数量进行设置。其矩形小段的规划分布模型采用随机规划,随机规划迭代次数为100次。
