摘 要:航材的可靠性是保证飞机完成遂行任务的基础,评估航材的可靠性可为保障决策提供依据;而目前相关的装备评估研究大多都是基于数理统计学的,其准确性会因样本的大小产生不可避免的误差;为了得到更准确的评估结果,文章引入逼近理想点(TOPSIS)法并改进了指标权重及理想解的确定方法,利用“合格得分线”概念,具体量化评估结果的等级划分,达到客观科学的效果;最后,通过实例分析,验证了文章方法在航材可靠性评估中应用的可行性,可为航材保障人员提供决策依据。

Abstract: The reliability of air materials is the basis to ensure the aircraft to accomplish the mission of implementation. And evaluating the reliability of air materials can provide a basis for support decision. At present, most of the relevant equipment evaluation studies are based on mathematical statistics, whose accuracy will inevitably produce errors due to the size of the sample. In order to get more accurate evaluation results, this paper introduces the TOPSIS method and improves the determination method of index weight and ideal solution, use the concept of“qualified score line”, achieve objectivity and scientific nature. Finally, the feasibility of applying the method in air material reliability assessment is verified through an example analysis, which can provide decision basis for air material guarantee personnel.
Key words: air material reliability; assessment; the TOPSIS method

航材的可靠性是保證飞机完成既定目标任务的重要保证,评估航材可靠性对于航材保障工作具有必要性。随着科技的飞速发展,装备技术显著提高,传统的检测方法已经很难准确地评估装备的可靠性。
对于装备的可靠性评估,已有很多专家学者提出了可行的方法,主要是基于数理统计学的方法来进行评估,但此类方法的评估准确性会因样本数据的大小波动明显。尤其是对新型装备进行评估时,由于使用时限短、历史数据少,得出的评估结果经常会有较大误差。而非基于数理统计学的评估研究虽有但很少,如:非线性指标聚合评估方法,是结合主客观打分法产生的一种方法,虽不受样本数据影响,但方法太偏向主观性,使评估结果的客观性不够充分[1-3]。针对……
