摘要: 针对 CHARTER 机制下的减灾卫星( 主要为成像卫星) 调度问题进行了研究, 介绍了 CHARTER 机
制的工作流程, 指出 CHARTER 机制下的减灾卫星调度实质上是一个针对区域目标的重调度问题。在此基础
上提出一种改进的区域目标划分算法, 并提出基于启发式规则的动态卫星重调度算法, 最后通过应用实例证
明了所提算法的正确性和有效性。

Abstract: The problem of disaster monitoring satellite ( imaging satellite) scheduling based on CHARTER mechanism is researched.
At the very beginning the mechanism on which CHARTER is working was introduced. The problem was taken as a rescheduling problem
against area targets according to the mechanism. To observe effectively, a dynamic partitioning algorithm for area target was proposed,
and a dynamic rescheduling algorithm was raised to support satellite re-rescheduling. Finally an example was constructed to testify the
correctness and validity of the algorithm proposed.
