    摘要:

    以實現對極軌氣象衛星應用系統健康程度進行綜合評價為目的,提出結合主觀分析的層次分析法(Analytic Hierarchy Process, AHP)和客觀分析的熵權法(Entropy Weight, EW)確定待評價系統指標值的綜合權重,再采用逼近理想解排序法(Technique for Order Preference by Similarity to an Ideal Solution,TOPSIS)對系統的指標進行多角度評價排序來作為最終評價結果。本文根據連續5個月3顆極軌氣象衛星在實際業務系統運行中異常指標樣本進行實證分析。結果表明該方法較為全面考慮了影響應用系統的多種因素,避免了單一判據的局限性,并對各指標的重要性進行綜合對比分析,使得評價結果更科學準確,可以作為構建極軌氣象衛星應用系統健康程度評價指標體系的一種方法。

    Abstract:

    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.
