Fuzzy-AHP approach for evaluation of green product designs

Environmental concerns have become an important topic in recent years. Nevertheless, selection of green product design is a decision-making process that is not easy to address, as this involves both qualitative and quantitative measures. Even worse, uncertain parameters could presence in the process. Therefore, a fuzzy-Analytic Hierarchy Process (AHP) is proposed in this paper to facilitate decision-makers making such decisions. AHP is a useful tool to tackle qualitative aspect of the problems, whereas fuzzy logic can deal with uncertain and vague parameters, which is not uncommon in real situations but is not sufficiently addressed by AHP. The rationale behind the model is to analyse the environmental impacts of different designs, with reference to the life-cycle assessment model using fuzzy-AHP approach.
