摘要: |
对地观测卫星(EOS)的应用任务建模是任务规划与调度的重要组成部分。从对地观测卫星系统的组成、应用任务特点以及建模基本要素等3个方面,对应用任务进行了详细的分析,其中特点包括任务周期性、严格的时间限制性、实体属性的复杂性以及任务的突发性等,建模基本要素主要包括约束条件和活动。在此基础上,使用规划领域定义语言(PDDL)对建模要素进行建模,主要包括约束条件和活动模型的标准化构建等。最后,给出了对地观测卫星对点目标的应用任务的建模案例,验证了任务建模适用于对地观测卫星任务规划。 |

Abstract: |
Modeling of earth observing satellite (EOS) application task is an important part in EOS mission planning and scheduling. From the perspective of the system components, characters of application tasks of EOS and modeling factors, a detailed analysis of EOS application task was accomplished. Among them, task periodicity, strict time limits, entity property complexity and suddenness of mission were investigated in characters of EOS application task. The constraints of task and actions were taken for the main modeling factors and applied to model EOS application task by plan domain define language (PDDL). Finally, through designing a case that EOSs take images from point target, the modeling method presented is illuminated and validated. |
Keywords: earth observation satellite application task plan domain define language(PDDL) modeling |
