摘要 研究装备质量评估中指标优化、权重确定、评估方法选取等问题.首先运用改进的群层次分析法(IGAHP)选取通用特性指标、测试数据指标作为状态评估的二级指标;在对质量状态进行定性划分的基础上,分别采用IGAHP、CRITIC(criteria improved through inter-criteria correlation)等方法对状态评估三级指标进行遴选和权重分析;然后,提出改进证据推理(ER)方法进行通用特性指标的评估,并采用CRITIC方法,基于客观权重进行测试指标降维优化,对各评估结果进行改进ER融合;最后通过算例验证所提出方法的有效性和优越性.研究结果表明:IGAHP-CRITIC组合赋权方法可有效综合主客观权重信息;通过指标优化可降低评估的维数和复杂度;考虑证据冲突的改进ER方法可有效降低评估的不确定性和不完备性. In equipment quality assessment, the problems of index optimization, weight determination and selection of assessment methods are discussed. Firstly, the improved group analytic hierarchy process(IGAHP) is used to select the general performance index and the testing data index as the second index of condition assessment. On the basis of qualitative division of the quality condition, the IGAHP and CRITIC methods are used to select and analyze the third level indicators of the assessment system. After that, an improved evidence reasoning(ER) approach is proposed to evaluate the general performance indicators, the CRITIC method based on objective weight is used to reduce the dimensionality of the testing data indicators, and the results are integrated by using the improve ER approach. Finally, the validity and superiority of the proposed method are verified by an example. The results show that the IGAHP-CRITIC combination weighting method can effectively integrate the subjective and objective weight information. Optimization of indicators can reduce the dimensions and complexity of the assessment. The improved ER method considering evidence conflict can effectively reduce the uncertainty and incompleteness of the assessment.
