Selection of Supply Chain Sustainability Management System by Fuzzy Additive Preference Programming Method

A selection of suitable sustainability management systems (SMS) is a major part supply chain strategies to create competitive advantage, reduce total costs, and manage long-term sustainability. framework method for prioritizing SMSs are presented in this research. Analytic hierarchy process (AHP) the most common alternative multi-criteria decision-making (MCDM). However, complex information mixed with ambiguity uncertainty, which makes decision makers unable use precise or crisp numbers, so fuzzy numbers remedy difficulty. Therefore, research proposes additive preference programming (FAPP) select optimum SMS chain. FAPP can produce unique normalized optimal priority vector pairwise comparison matrices effectively linear constraints. The constraints eliminate weaknesses existing methods equalize upper lower triangular judgments. In addition, proposed identify abnormal pairs judgments that cause inconsistency. methodology prioritize key criteria lead appropriate SMS. An example rubber factory demonstrates feasibility validity method.
