Identifying and Ranking the Barriers to Sustainable Supply Chain Management, Using a Hybrid Fuzzy ANP-DEMATELApproach: A Case of shipyard in Bushehr

Sustainability  is a relatively new and very influential subject that has attracted the attention of researchers in the field of supply chain management. In addition to the academic field, societies, governments, businesses, international agencies and nonprofit organizations are increasingly focusing on this issue.The present study seeks to investigate the barriers to implementation of sustainable supply chain management practices in Bushehr Shipbuilding Plant using fuzzy and nonlinear ANP methods. Using a questionnaire method, among 50 experts in the supply chain of Bushehr Shipbuilding Company, 30 individuals were identified as the sample of which 20 completed the questionnaire. then a fuzzy DEMATEL method was used to build a framework for evaluating the impact of indicators. In the next step, using the fuzzy ANP technique, the barriers were studied. The compatibility rate of the performed comparisons is 0.019, which is less than 0.1, and therefore it is possible to trust the comparisons. According to the results, the knowledge and support dimension have the highest impact, in the ranking stage, three highest pririties are respectively, sustanability cost and economics condition (weight 0.124), lack of technical expertise (weight 0.099), and lack of training (weight 0.081). Regarding the results, it can be recommended that in implementing sustainable supply chain management it is crucial to learn from the supply chain  (i.e knowledge dimension) through collaboration.
