绿色产品多级模糊评价方法的研究

Research on the Method of Multilevel Fuzzy Evaluation of the Green Products

采用多级模糊综合评价方法解决了综合考虑产品在全生命周期或多生命周期内从设计、制造、使用及回收利用等方面众多因素的影响下的评价问题。评价过程不仅考虑了所有因素的影响 ,而且保留了各级评价的全部信息。通过权重系数可突出重要的评价项目 ,评价结果直观地反映了实际情况 ,且便于评价和比较 ,并通过实例说明了评价过程。

The appraisement of the “green degree” for a green product is a problem that is considered as multilevel evaluation of multi-aspect and multi-stratification. The multilevel fuzzy evaluation solves the problem that considers the influences of design, manufacture, usage and recycle in all-life cycle or multi-life cycle of the products. In the evaluation process it is not only deal with the action of all factors but also continue to remain all messages in evaluation. The weighting coefficients can stand out the main items. The results are impersonal and intuitionistic,which can be to easy appraise and compare. There is an example that introduces the evaluation process.
