基于AHP的遥感卫星任务规划效能评价方法

An AHP-based Approach for Evaluating Mission Planning Efficiency of Imaging Satellites

目前,针对遥感卫星任务规划问题的求解算法种类繁多,但是对算法效能进行客观定量的综合评价一直是个难题。对此,提出了一个面向应用的算法效能评价机制,给出了标准测试算例集的生成方法,并首次从资源利用率和任务满足度2个方面,抽取建立了算法的分层评价指标体系,基于层次分析(Analytic Hierarchy Process,AHP)算法和Delphi算法建立了算法效能的综合评价模型,给出了具体的评价步骤。通过2个算法的实例对比分析,验证了方法和模型的有效性。

There are many kinds of algorithms of mission planning for imaging satellits presently, but it is difficult to evaluate the efficiency of thses algorithms. An approach based on application is proposed, the method to build the test examples is given, the index system is designed considering the rate of resource consuming and the degree of mission satisfaciton, and the model of evaluation is constructed based on the AHP algorithm and Delphi algorithm. At last, two mission planning algorithms are evaluated and compared, which verifies the effectiveness of the approach and the model.
