An Integrated Decision-Making Approach for Green Supplier Selection in an Agri-Food Supply Chain: Threshold of Robustness Worthiness

Along with the increased competition in production and service areas, many organizations attempt to provide their products at a lower price higher quality. On other hand, consideration of environmental criteria conventional supplier selection methodologies is required for companies trying promote green supply chain management (GSCM). In this regard, multi-criteria decision-making (MCDM) technique based on analytic hierarchy process (AHP) fuzzy order preference by similarity ideal solution (TOPSIS) used evaluate rate suppliers. Then, considering resource constraint, weight rank suppliers are taken into account multi-objective mixed-integer linear programming (MOMILP) determine optimum quantity each under uncertain conditions. To deal multi-objectiveness proposed model, robust goal (RGP) approach Shannon entropy applied. The offered methodology applied real case study from food manufacturing company Iran verify its applicability sensitivity analysis performed different uncertainty levels. Furthermore, threshold robustness worthiness (TRW) studied applying budgets company. Finally, discussion conclusion provided, an outlook future research projects given.
