Abstract :

Background and Aim: Due to the existing dynamics, it is necessary to achieve the goals of supply chain management of refractory industries, creating coordination between different levels of supply chain, identifying influential factors and identifying how different risks interact, which ultimately requires analyzing large volumes of information. For this purpose, the purpose of the present study is to provide a mesh line model in the management of supply chain risks of raw materials in conditions of uncertainty with a dynamic approach to systems in refractory industries.  Method: In terms of purpose, the present study is part of applied research. The statistical population of the study included the managers of refractory industries in the country, which was selected as a sample size by a purposeful method available to 15 people. Library and field methods and refractory industry database tools were used to collect information. In order to analyze the data, the systems dynamics approach and Wensim software were used.  Results: The simulation results showed that there are two mesh lines to reduce supply chain risks that in the structure of cooperation between suppliers and partners, it is important to pay attention to long-term returns and in shaping key factors to reduce supply chain risks in the absence of conditions. Certainty in the refractory industry, it is necessary to focus on the fact that long-term returns should be considered in the short run.  Conclusion: According to the findings, in order to reduce supply chain risks in the uncertainty of refractory industries, in the short term, they should focus on reducing the level of differences in work situations and conflicts between them, and partners and suppliers in the long run to resolve conflicts. They should be non-functional in the system and keep its level to a minimum.
