with gray possible degree to evaluate GSCM criteria in the supplier
selection. This study examines the consistency approaches by factor
analysis that determines the adoption and implementation of green
supply chain management in Taiwanese electronic industry. The
fuzzy analytic hierarchy process method is applied to prioritize the
relative importance of four dimensions and twenty approaches
among nine enterprises in electronic industry. Also, Tseng et al.
(2010b) investigated a set of qualitative and quantitative
measurements of environmental practice in knowledge management
capability by a novel hybrid multi criteria decision-making
model to address the dependence relationships of criteria with
the integration of the analytical network process and DEMATEL.
Chang et al. (2011) analyzes fuzzy DEMATEL method identifies
