Intuitionistic fuzzy sets on Performance Evaluation of the supply chain using Supply chain operations reference (SCOR)

Evaluation of the supply chain encompasses various functions aimed at performance improvement, efficient resource management, identification of strategies to address current challenges and weaknesses in the existing supply chain, and ultimately, sustainable development of the company. Aimed to identify criteria and sub-criteria for evaluating the supply chain using dimensions of the operational supply chain model within this company. The operational supply chain model was adopted as a reference, and sub-criteria were extracted based on the dimensions of reliability, responsiveness, quality, cost, and asset management. Using the DEMATEL method, causal relationships among 24 sub-criteria were defined in a fuzzy Intuitionistic environment, and then weighted using the Analytic Network Process (ANP) with three types of data: crisp, fuzzy, and fuzzy cognitive. Weighting with all three methods was compared, showing that fuzzy Intuitionistic data yielded significantly more accurate results. Finally, decision-making units were ranked, with Decision Unit 1 achieving the highest rank and Decision Unit Eight the lowest.
