摘　　要：基于对成像卫星任务规划问题的特点的深入分析,提出一种基于状态-动作模型的任务规划建模的方法:采用PDDL语言对成像卫星的领域知识进行描述,解决动作的持续时间约束、复杂的资源约束和一类特殊的外部事件约束的表达问题,最终建立成像卫星任务规划模型。通过对该建模方法的模型描述能力分析,表明该建模方法较传统规划建模方法具有较好的描述能力,能满足描述成像卫星任务规划问题的要求。Based on analysis of mission planning for imaging satellite, a new approach for modeling mission planning based on state and action models is proposed. The processing steps include： adopting PDDL language to describe the domain knowledge of imaging satellite; solving representation problems of duration constraint, resource constraint and one particular exogenous event constraint. Finally, the domain model of mission planning for imaging satellite is constructed. Compared with traditional planning approach, the proposed approach has good representation capabilities and can meet the requirements of representing the problem of mission planning for imaging satellite through analyzing its model representation capabilities.
