绿色产品设计决策的影响评估算法

Algorithm of lmpact Assessment of Green Design Decision

将各种排放物影响因子进行分类后 ,应用灰色系统理论 ,提出了影响评估灰类划分及其白化权函数 ,对各影响类别进行了灰色聚类分析 ,而后根据分析结果给出了分类影响指数的计算方法 .根据各影响类别的作用范围 ,将影响类别按全球影响、区域影响、本地影响进行了分组 ,并给出了分组影响指数以及总体影响指数的计算方法 .最后 ,以设计中的材料选择为例 ,说明了该方法在一类产品比较选择中的应用 .

After classifying the impact factors of emissions,with grey-system theory,the evaluating grey-groups and their whitening weighing functions are defined.The grey-cluster analysis of each classified impact is performed.Based on analyzing the results,the calculating method of classified impact index is given.By the range of action,the impact classes are grouped into three groups,namely global impact,regional impact,and local impact.The calculating methods of the grouped and the over all impact index are presented.Finally,to illustrate the application of the above method in the comparative choice of a category of products,an example of material choice in design is given.
