灰色关联分析在工程机械质量评估中的应用

Application of gray relational analysis to quality evaluation of construction machinery

将灰色关联分析法运用于工程机械质量水平的评估,建立了工程机械质量水平评估模型,并以液压挖掘机为例阐述了应用该模型进行质量水平评估的基本步骤,结果表明它具有较高的准确性和实用性,同时该模型也适用于其他具有多指标评估选优性质的问题。

In the paper, gray relational analysis method is used to evaluate the quality of construction machinery. A gray evaluation model based on the gray-system theory was built to do it and the basic procedures of quality evaluation was pointed out during the quality evaluation of practical excavators. The result of the quality evaluation of the excavators shows that the method is accurate and practical, and the model can also be applied to other multi-purpose evaluation. The result of the quality evaluation of the excavators shows that the method is accurate and practical.
