在此基础上给出了系统的总体设计和各子模块的功能

重点阐述了时间窗口计算模块

提出区域目标的动态分解算法。借助基于规则的动态启发式算法生成卫星任务规划方案

提出三项指标对方案进行评价。

Abstract

A system for scheduling of disaster monitoring satellites which follows the tenet and operation mechanism of CHARTER is developed. First

it introduces the significance and mechanism on which CHARTER is running and then details the design and implementation of the system. At the same time detailed function of each module is given out. Great attention is paid to the analysis module of tasks’ time windows. In the process of the computation of the targets’ time windows

a dynamic partition algorithm for area target is introduced. Then a dynamic scheduling algorithm is constructed to create schedule plan for disaster monitoring satellites. Also the paper develops three variables to evaluate the plan created

and gives out the meaning of each variable respectively.
