The main aim of this study is proposing an assessment model for evaluating the supply chain sustainability across the automotive sector. In this study, through reviewing the sustainability indicators in the economic, social, environmental, and governance pillars, the fuzzy Delphi is applied. Then, survey method is used to implement the model designed in CANFIS to evaluate the sustainability indicators. In this research, the proposed model was used for evaluating the sustainability in four pillars which is more inclusive than previous research. To improve the sustainability, it must be evaluated and measured so that after the improvement measures, the results are determined through measurement. According to the findings, it was concluded that the model designed in CANFIS was a reliable tool for assessing the sustainability. Manuscript profile

Today's competitive world has led managers to shift from traditional management to scientific management. Supply chain management is one of key issues in industries because, considering a high number of competitors in today's competitive world, competition has been extended from company level to the level of competition on their supply chain. For any organization seeking to achieve its goals in conditions of economic competition, timing, and quality of services, especially in an economic environment is characterized by globalization of business and acceleration of industrial cycle. Thus, this study was conducted to identify supply chain sustainability factors by applying fuzzy Delphi approach. Firstly, by reviewing theoretical literature, four dimensions of economic, social, environmental, and governance were selected as main dimensions as well as 46 indicators as sub criteria. Finally, after three stages of Delphi method, experts agreed on 41 indicators. The indicators that have been most agreed upon by experts are: the use of non-renewable energy in the environmental dimension with a score of 0.84, the rate of employees trained in the social dimension with a score of 0.80, financial performance and market share and quality. In addition, product safety in the economic dimension with a score of 0.77 and interaction and partnership with stakeholders and value creation for shareholders and stakeholders in the governance dimension with a score of 0.77. Now, managers can increase the sustainability of the supply chain by considering these indicators in targeting and formulating the relevant strategy. Manuscript profile
