装备维修保障效能评估指标权重组合赋权法的研究

Study on Equipment Maintenance Support Performance Evaluation Index Weights of Combination Weighting Method

针对现有的主观赋权法、客观赋权法的各自优缺点,提出基于最小二乘法原理的组合赋权法思想。利用利差函数与目标规划方法得到了组合赋权法唯一最优存在定理;使用高等数学、线性代数等知识证明了定理的存在性及唯一最优性,并给出了组合赋权的表达式。该方法将主观权重与客观权重加权综合起来,使效能评估的分析结果同时反应了主观意愿和客观情况,为效能评估结果的可靠性与准确性打下了基础。

Aiming at subjective weighting and objective weighting for the existing law,the respective advantages and disadvantages,put forward based on least square theory combination weighting method thinking.Spread function and the use of goal programming method to get the optimal combination weighting method the only existence theorems;use of advanced mathematics,linear algebra and other knowledge to prove the theorem of existence and uniqueness of optimal,and gives the combination weighting expression.The method of subjective and objective weight weighted weights together,so performance evaluation results will also reflect the subjective and objective conditions for the performance evaluation results of the reliability and accuracy of the foundation.
