Evaluating the Green Supply Chain Management using Life Cycle Assessment Approach in Uncertainty
Authors: ,
Abstract: Green supply chain management in product life cycle assessment is a complex uncertainty concept that is difficult to determine based on a firm’s real situation because measuring GSCM requires a set of qualitative measures. A set of criteria is proposed and uses a hybrid fuzzy multi-criteria decision-making (MCDM) technique to address the dependence relations of criteria in hierarchical structure with the aid of the interpretive structural modeling (ISM) and analytical network process (ANP) in linguistic preferences. Fuzzy set theory is used to interpret the linguistic preference in accordance with the subjective evaluation. The evaluation results obtained through the proposed approach are for two reasons. First, the results are generated by a group of experts in the presence of motile criteria, and second, the linguistic preference approach reduces the distortion and loss of information. Managers judge the need to improve and determine which criteria provide the most effective direction towards improvement. The results and implications are discussed.
