| Evaluating influential factors of green supply chain management using dual-aspect fuzzy DEMATEL method |
Jih Kuang Chen 1*
Abstract
Decision Making Trial and Evaluation Laboratory (DEMATEL) and fuzzy DEMATEL (FDEMATEL) methods are often used to observe cause and effect relationships among green supply chain management (GSCM) factors. This paper argues that both methods target the mutual influence among contained factors as one entity, however, various factors may oppose each other, be in positive or negative relation to each other, or encompass other meaningful information per the relationships among them. The influential GSCM factors implicitly encompass both economy (e.g., product, production, income) and ecology (e.g., emissions reduction, green design) which may be contradictory. Evaluating the mutual influence among factors as one entity may lead to erroneous decisions. A dual-aspect fuzzy DEMATEL method is proposed in this paper to divide these GSCM factors into two separate categories, “economy” and “greenness”, then isolate them for analysis via FDEMATEL. They can then be further integrated to split them into a “cause” group or “effect” group. Organizations would benefit from focusing on cause group factors. A case study was conducted to validate the feasibility and effectiveness of the proposed method. The results of this work may provide workable guidance for organizational GSCM practices, as well as further research on the similar subjects.
