摘要
为了将高分对地观测系统的观测任务分配到卫星和地面站资源上,并满足任务的逻辑、时间和资源约束,设计了一种通用任务规划框架。该框架的核心是分离式资源模板、分层任务模板和通用决策引擎。针对多类型资源定义了分离式资源模板,实例化资源组件映射对地观测系统的各功能结构,以资源组件的组合方式构成对地观测系统的通用描述;针对复杂任务模式定义分层任务模板,将复杂任务分解为带有因果约束的活动网络;针对资源和任务的通用描述设计通用求解引擎,将复杂决策分解为人机结合的决策过程,以最大化满足用户需求。介绍了通用任务规划的框架设计,并通过应用实例说明了该框架对问题的描述和求解过程。
To assign tasks of high resolution Earth Observation Satellite system（EOSs） to satellites and ground station resources while satisfying tasks＇ logical,temporal and resource constraints,a general mission planning framework was designed.The detachable resource template,hierarchy mission template and general decision engine were the core of this framework,and the detachable resource template was defined for multi-types resource.Each functional configuration of EOSs was mapped by instantiation,and the general description of EOSs was constructed by resource component.Aiming at the complex mission modes,hierarchical mission template was presented as a process of decomposing complex mission into an activity graph with causality constraints.General solution engine for general representation of resource and task was designed,and complicated decision was decomposed into mix-initiative cooperative decision so as to satisfy maximum customers＇ requirements.A general mission planning platform for EOSs was introduced.Application examples were used to explain problem representation and solution process in the framework.
