    摘要:

    随着地球观测领域相关技术的高速发展, 近年来具有先进姿态调整能力的敏捷地球观测卫星已经引起了广泛的关注. 敏捷卫星任务调度具有时间依赖性切换时间, 在多星、多轨道、多需求的卫星观测场景下, 产生了复杂的时间依赖性多敏捷卫星多目标调度问题. 针对该问题, 首先, 基于问题特征和优化目标建立问题的数学规划模型; 其次, 提出一种分布式元$ Q$学习协同进化框架, 包括预训练和进化搜索两个阶段, 预训练阶段通过分布式$ Q$学习提高训练效率, 进化搜索阶段通过训练好的分布式$ Q$学习模型实现多种群进化算子的自适应选择; 然后, 基于所提出的进化框架和问题特征, 设计多样化的进化算子和动态种群划分选择策略, 建立一种分布式元$Q $学习协同进化算法(DMCEA); 最后通过实验验证DMCEA求解问题的有效性.

    Abstract:

    With the rapid advancement of earth observation technologies in recent years, agile earth observation satellites (AEOS) equipped with advanced attitude adjustment capabilities have attracted widespread attention. The scheduling of AEOS involves time-dependent transition times, which generates a complex time-dependent multi-objective scheduling problem in multi-satellite, multi-orbit, and multi-demand observation scenarios. To solve this problem, we first formulate a mathematical programming model based on the problem characteristics and optimization objectives. Subsequently, a distributed meta-$Q $-learning co-evolutionary framework is proposed, which consists of a pretraining phase and an evolutionary search phase. In the pretraining phase, distributed $Q $-learning is used to enhance the pretraining efficiency, while the evolutionary search phase leverages the pretrained distributed $Q $-learning model to adaptively select the evolutionary operators. Based on the proposed evolutionary framework and problem characteristics, different evolutionary operators and a dynamic population division strategy are designed. Further, a distributed meta-$Q $-learning co-evolutionary algorithm (DMCEA) is constructed. Finally, computational experiments validate the effectiveness of the DMCEA in solving the problem under consideration.
