系统科学视角下高分辨率对地观测系统任务管控统筹优化

高分辨率对地观测系统因其高清晰度的影像产品倍受测绘、农业、林业、采矿、城市规划、国土资源等众多领域的用户青睐.在面对不同用户各种繁杂的任务需求和超过载的卫星影像订购,以及在云层遮挡等随机因素干扰下,如何通过对任务统筹管控来提升系统整体效益已成为航天领域一个崭新的管理科学问题.通过对高分辨率对地观测任务管控流程的分析,指出了星务管控的关键在于卫星任务规划和星地资源调度问题,并围绕问题基本输入要素和输出要素构建了该问题的概念模型.通过与车辆调度、车间作业调度等常见资源调度问题对比,强调了该问题的特殊性和巨复杂性,并从任务、资源、约束和优化目标四方面进行了详细论述.最后,基于系统科学观的思想提出采用统筹优化的方法来处理高分辨率对地观测系统任务管控问题,并从系统层次性、涌现性和协调性角度进行了系统分析.

Planning overall high-resolution earth observation system mission in the perspective of systems science

High-resolution earth observation system wins the favor of users of surveying,agriculture, forestry,mining,urban planning,land resources and other fields,for its high-definition video products. Meanwhile,a new problem of management science emerges.This problem is how to improve the whole efficiency of the system by handling overall its mission,from different users' needs and usually oversubscribed, under the circumstance of the random interference of cloud and others.Through the analysis of the management f...
