An Analysis of the Barriers to the Implementation of the Circular Economy and Industry 4.0 in the Supply Chain: The Meta-Synthesis Approach and Fuzzy DANP

The purpose of this research is to identify and investigate the relationship between the barriers to the implementation of the circular economy and Industry 4.0 in the supply chain in one of the polluting industries of the country (Yazd Glass Complex). In order to identify the barriers and categorize the barriers, the Meta-Synthesis approach was used, and in the quantitative part, in order to present the pattern of relationships between these barriers and their prioritization, the combined method of Fuzzy DEMATEL- ANP (FDANP) was used. The findings of the qualitative section included the identification of 24 obstacles in 5 dimensions. In the quantitative part, the findings showed that economic, infrastructural and technical-legal barriers are considered as causal dimensions that affect human resources and organizational-management (Effect) dimensions. Also, the obstacles of lack of expertise and knowledge of employees regarding the circular economy and Industry 4.0; Fear of unemployment and resistance to organizational and process changes and lack of funds and financial tools for training and research and development and operations are the most important obstacles in the implementation of the circular economy and Industry 4.0 in the supply chain of polluting industries such as the glass industry.
