摘要： 为客观有效地评价产品的总功能和全性能(广义质量),以物元模型为基础,结合广义质量指标体系和评价的一般过程,在指标的权重确定中综合了层次分析法和熵值法.同时对于不同性质的指标采用了不同的从优模式,排除了由于各项指标单位不同以及其数值数量级之间的悬殊差别所带来的影响,从权重确定和指标质量两个方面均对一般评价方法做了改进,避免了不合理结果的产生.以经济型轿车为例,用基于组合权重的产品广义质量综合评价法对其综合性能进行了评定.结果表明,此方法能合理地分配指标的权重,有效地对产品进行综合评价,评价结果全面体现了产品的综合性能,为用户选择产品,企业制定产品战略提供科学依据.

Abstract: Based on the fuzzy matter element model and generalized quality evaluation indices, a relevant evaluation was done objectively and efficiently for products' overall quality/performance, where the index weights were determined by AHP in combination with entropy weight coefficients so as to exclude the influences from the difference between index units especially between the orders of magnitude of index values. Thus, the irrational outcome can be avoided by determining both index weights and performance indices. Taking a car as example, its overall performance was evaluated with the generalized quality evaluation using combination weights, and the results showed that the index weights are reasonably assigned with its overall performance evaluated properly and completely. The evaluation method can provide scientific reference for customers to select the products they desire and make the strategy for the enterprise to develop their products.
