摘　　要：以实现对极轨气象卫星应用系统健康程度进行综合评价为目的,提出结合主观分析的层次分析法(Analytic Hierarchy Process,AHP)和客观分析的熵权法(Entropy Weight,EW)确定待评价系统指标值的综合权重,再采用逼近理想解排序法(Technique for Order Preference by Similarity to an Ideal Solution,TOPSIS)对系统的指标进行多角度评价排序来作为最终评价结果。本文根据连续5个月3颗极轨气象卫星在实际业务系统运行中异常指标样本进行实证分析。结果表明该方法较为全面考虑了影响应用系统的多种因素,避免了单一判据的局限性,并对各指标的重要性进行综合对比分析,使得评价结果更科学准确,可以作为构建极轨气象卫星应用系统健康程度评价指标体系的一种方法。In order to realize the comprehensive health evaluation of the polar orbiting meteorological satellite application system,the comprehensive weight of the index value of the system to be evaluated is determined by combining the Analytic Hierarchy Process(AHP)of subjective analysis and the entropy weight(EW)of objective analysis,then the TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution)is used to rank the indexes of the system from multiple angles as the final evaluation result.In this paper,three polar orbiting meteorological satellites in five consecutive months are used to analyze the abnormal index samples in the actual operation system.The results show that this method considers many factors that affect the application system comprehensively,avoids the limitation of single criterion,and makes a comprehensive comparative analysis of the importance of each index,making the evaluation results more scientific and accurate,and it can be used as a method for the health evaluation of the polar orbiting meteorological satellite application system.
