摘要： 研究了空间对地观测中配备多个有效载荷时的观测任务规划问题。首先建立了该问题的组合优化数学模型,优化指标考虑了科学和经济利益的最大化和各项资源约束;然后应用遗传算法对该问题进行了求解,并与贪婪算法结果进行比较;最后,验证了模型的有效性和算法的优越性。

Abstract: The earth observation missions planning was presented when there were several instruments on board.First,a set of mathematical models of this combined optimal problem were set up,in which we consider the maximum of science and economy benifits and the limitation of resources.And then,this combined optimal problem was studied by using genetic algorithm.Some computer simulations were performed.The results show that the model is valid and the genetic algorithm is better than greedy algorithm.
