产品生命周期评价模型研究

A Model for Product Life Cycle Assessment

运用全生命周期分析方法对产品的性能进行分析,采用线性标度法和层次分析法建立产品全生命周期评价模型。在获得产品全生命周期数据清单之后,通过对各种指标进行量化、标度和权重计算,根据分析结果评价产品的性能,从而实现产品性能评价由定性向定量的转化。

Life cycle assessment was used to evaluate the performances of product,and linear scale and analytic hierarchy process were applied to establish the model for product life cycle assessment.After attaining the data inventory of product life cycle,the model can carry on quantization,linear scaling,and weighting for the different indexes,and then the indicators,which assessed the degree of product performances,were realized from qualitative to quantitative on the basis of the analysis result.The validity of the model was demonstrated by a beverage packaging.
