ABSTRACT

The phrase “sustainable supply chain management techniques” refers to a collection of tactical activities that may assist a corporation in achieving more sustainability in the economic, environmental, and social aspects of sustainability. These kinds of activities center on the process of implementing sustainable supply chain management, which significantly impacts the level of sustainability performance a firm achieves. It is generally agreed upon that one of the most important aspects of sustainable supply chain management strategies is identifying sustainable vendors. This is because the activities of suppliers are essential to assisting downstream businesses in achieving a collaborative and sustained competitive advantage. In addition, the selection of a supplier may be thought of as a process of multi-criteria decision-making (MCDM), which is comprised of two stages: the calculation of the weights of the criteria and the ranking of the suppliers. The model used consists of two multi-criteria decision-making (MCDM) methods, the CRiteria Importance through Intercriteria Correlation (CRITIC) method, and the Combinative Distance-based ASsessment (CODAS) method. The model used is conducted under the IFS environment and using IFNS. Initially, the CRITIC method prioritizes criteria and determines their weights. Then, the CODAS method ranks and selects the best available alternatives.
