基于权值重组的装备效能评价指标权重的确定

Determination of Evaluation Index Weight of Equipment Efficiency Based on Weight Reconfiguration

在分析装备效能评价工作重要性的基础上,以车载发配电系统为研究实体,建立其效能评价指标体系;利用权值重组方法确定指标的组合权值,重点对多种方法确定的权重值进行比对,讨论确定指标组合权值的合理性,同时,根据分析结果找出影响系统效能的关键指标。结果表明,这种方法能合理突出重点指标的作用,使多层次指标体系合理构建和优化组合,可实现整体评价的最优或满意。该方法可为科学客观地确定系统效能评价指标的权重提供有益的参考。

Based on analyzing the importance of equipment efficiency evaluation, the paper establishes the efficiency evalu- ation index system of on - vehicle generation and distribution system （ GDS）, calculates the combinational weight of the in- dex by weight reconfiguration method, compares the weights got from various methods, discusses the rationality of combina- tional weight calculation method, and identifies the key indexes affecting the system efficiency according to the analysis re- sult. It concludes that the method highlights the use of key indexes, reasonably builds and combines multi - level index sys- tem, and achieves optimal and satisfactory overall evaluation. The method offers beneficial reference for determining the e- valuation index weight of equipment efficiency scientifically and objectively.
