AI总结:

本文针对需求不确定性下的在轨服务作业,提出结合扩展的空间物流技术与滚动时域决策方法的建模优化框架,通过混合整数线性规划高效求解,并经案例验证其在短期调度和长期战略决策中的有效性。

摘要:

本文提出了一个框架,用于对包含一个或多个服务航天器与轨道仓库的复杂在轨服务基础设施的作业进行建模和优化,以向地球静止轨道卫星群提供多种服务。该方法通过解决在轨服务应用中的独特挑战,扩展了最先进的空间物流技术,并将其与滚动时域决策方法相结合。空间物流技术能够将在轨服务后勤作业建模为混合整数线性规划问题,其最优解可高效求解;滚动时域方法通过考虑地球静止轨道卫星随时间产生的不确定服务需求,能够评估在轨服务基础设施的长期价值。两个案例研究成功证明了该框架在(1)短期作业调度和(2)不同市场条件下在轨服务架构的长期战略决策中的有效性。

英文摘要:

This paper develops a framework that models and optimizes the operations of complex on-orbit servicing infrastructures involving one or more servicers and orbital depots to provide multiple types of services to a fleet of geostationary satellites. The proposed method extends the state-of-the-art space logistics technique by addressing the unique challenges in on-orbit servicing applications, and integrate it with the Rolling Horizon decision making approach. The space logistics technique enables modeling of the on-orbit servicing logistical operations as a Mixed-Integer Linear Program whose optimal solutions can efficiently be found. The Rolling Horizon approach enables the assessment of the long-term value of an on-orbit servicing infrastructure by accounting for the uncertain service needs that arise over time among the geostationary satellites. Two case studies successfully demonstrate the effectiveness of the framework for (1) short-term operational scheduling and (2) long-term strategic decision making for on-orbit servicing architectures under diverse market conditions.
