摘要 在多星联合调度过程中,存在着很多不确定性因素,其中云层覆盖变化是主要的不确定性来源。本文针对考虑云层覆盖变化的多星联合调度问题,借鉴了连续函数的鲁棒性优化思想,提出了一种基于邻域的鲁棒性指标。在此基础上,建立了多星联合鲁棒性调度模型,给出了观测任务优先级的计算方法。实例研究表明,本文建立的模型能够在保证调度方案性能的基础上,获得鲁棒性强的调度方案。 The possible presence of clouds is the main origin of uncertainty in the multi satellites joint scheduling problem. Considering this uncertainty, we propose a neighborhood-based robustness measure for scheduling which is inspired by advances in robust optimization of continuous functions, construct a multi satellites joint robust scheduling model, and put forward a method to estimate priority of observing task. Numerical results indicate that our model can get a robust schedule with high performance.
