基于组合赋权法和Vague集理论的预警卫星探测效能评估

Efficiency Evaluation of Reconnaissance Satellite Intelligence Processing Systems based on Combination Weight Method and Vague Set

针对传统预警卫星探测效能评估方法中存在模糊性、缺乏数学定量评价的问题,提出基于组合赋权法和Vague集理论的预警卫星探测效能评估方法。将区间层次分析法与改进CRITIC法相结合,系统指标权重由主客观组合赋权确定;构造Vague集决策矩阵,计算Vague集加权相似度,利用综合决策规则评估系统效能优劣。实例分析结果表明,该方法能有效评估预警卫星系统探测效能,为导弹预警防御系统整体效能评估提供方法指引。

For fuzziness and lack of mathematical quantitative evaluation in traditional evaluation methods of reconnaissance satellite information processing systems,an evaluation method was proposed based on subjective and objective comprehensive weight assignment combined with Vague set theory.Interval analytic hierarchy process and improved critic method were adopted to determine the expert weight and the objective weight of evaluation indicators,and the comprehensive weight of indicators was determined by game theory aggregation model.Then calculate the weighted similarity of the constructed Vague set and combine the comprehensive decision rule to evaluate the effectiveness of the system.The results of a concrete computation example showed that the method could effectively evaluate the effectiveness of the early warning satellite,which laid a foundation for the overall evaluation of the effectiveness of missile early warning and defense system in the next step.
