Abstract:

Aiming at the problem of weights decision of green-assessment-indexes, a new method based on the analytic network process (ANP) and theory of life cycle assessment (LCA) is proposed to compute the assessment indexes' weights. Firstly, the assessment indexes in life cycles of a product are presented. Secondly, according to the correlations among different indexes in the same hierarchy, the weights of green-assessment-indexes in different life cycles of a product are decided by the ANP. The results indicate that the analysis by the proposed method is more comprehensive and objective than that by the AHP alone.

Key words: green products assessment, life cycle assessment, analytic network process
