| 摘 要： | 遥感应用需求中存在点目标和区域目标两类任务,遥感卫星对两类任务的调度方式存在很大区别,将二者统一调度困难.本文将点目标视为特殊的区域目标,将它们按照卫星观测机会分解,构建元任务,将两类目标在元任务层次进行统一;根据任务类型分别构建收益函数,兼顾了二者在收益计算上的差异,并建立了面向点及区域目标的遥感卫星任务调度模型,实现了对两类任务的综合调度.仿真实例证明,此方法能够提高卫星的观测效率.

| Abstract: | Two types of tasks,the spot and polygon targets,are requested in remote sensing.However,great difference exists between the two request tasks and it is difficult to schedule the two kinds of requests within one model.In this paper,a novel model is proposed to tackle it by the following method.The spot requests are regarded as special polygon and they are also partitioned into subtasks.All of the subtasks generated by the requests are mapping into atomic task,and two types of request were unified in atomic t... |
