可持续技术的综合评价方法探讨

从生命周期的角度,界定了可持续技术的内涵,提出了可持续技术的分类方法,将可持续技术分为5类,探讨了技术综合评价的一般过程。对4种印染废水处理技术(分别记为A、B、C、D)进行了实证分析,给出了评价指标,采用3种客观赋权法对指标赋权,运用灰色关联度模型对技术的可持续性进行排序。从评价结果看,4种技术的可持续性依次为D>A>B>C。然后,分别分析了各技术的经济、环境、社会效益情况。最后,对评价结果的不确定性进行了简要分析。

Study on Comprehensive Evaluation Method of Sustainable Technologies

The connotation of sustainable technology is defined,from the perspective of life cycle assessment.The classification of sustainable technology which is classified as five classes,is put forward,and general process of technology comprehensive evaluation is also discussed.Then four kinds of dyeing wastewater treatment techniques(marked as A,B,C,D,respectively)are analyzed,as a case study,the evaluation index is developed and three objective weighting methods are applied to weigh the index,then the grey relat...
