This study tempts to analyze fuzzy DEMATEL which is proposed
method to identify main GSCM criteria described in practices,
performances and external drivers that affect on implementing
GSCM, also their criteria interrelationships assessment are
acknowledged in this study. With the combination of fuzzy set
theory, this examination will solve the distortion and loss of
information of human judgments by convert linguistics preferences
to fuzzy numbers. The study obtains direct and indirect influence
among criteria using the DEMATEL technique, and computes the
causal relationship and strength among criteria. The DEMATEL
technique does not need large amounts of data. This method is used
to fill the gaps between the interactive relations of those criteria
(Chen et al., 2011; Tseng et al., 2009c; Chang et al., 2011; Zhou
et al., 2011).
