基于灰色层次分析的产品广义质量综合评价研究

以提高产品质量为出发点,深入分析了产品质量的内涵和外延,提出了产品广义质量的概念,确立了产品广义质量目标体系,其中包含结构性能、工作性能和工艺性能在内的产品全性能和全功能指标簇;较全面地考虑了产品广义质量的层次性和复杂性.采用AHP和灰色理论相结合对产品广义质量进行评价,兼顾产品广义质量的模糊性、复杂性和难以量化等特点.以某国产挖掘机为例,对其广义质量进行了综合评定;结果表明,广义质量及其评价体系可以为产品的设计制造、质量评价和企业定位提供科学参考及决策依据.

Generalized Evaluation Based on AHP/Grey Theory for Product Quality

To improve product quality,the product quality is analyzed in depth in a broad sense involving its connotation and denotation.An idea of generalized product quality is thus presented with a relevant evaluation index system suggested including all functions and comprehensively clustered performance of a product in view of its construction,operation and process technology.In this way the complexity and relational hierarchy of the generalized product quality in evaluation are fully considered by introducing AHP in combination with grey theory to make the fuzziness,complexity and difficulty in quantification compatible with each other.Then,taking a domestic excavator as example,its generalized product quality is evaluated comprehensively,and the results show that the generalized evaluation system for product quality can provide a scientific basis for decision making on product design/manufacture,quality evaluation and orientation of enterprise.
