 Iran's carpet industry is one of the most important industries among non-oil exports for a long time. One of the most important concerns in this industry is the issue of choosing the right supply chain policy. On the other hand, among the issues affecting the knowledge-based economy, attention is paid to the development of the technology ecosystem and innovation. Therefore, in this article, after studying the available sources, the functional variables in the carpet supply chain have been identified, and then, based on the systems dynamics approach, the cause and effect relationship between all the variables has been considered and the desired system has been simulated. In the following, the possibility of applying the scenario in Vansim software was used, and the results showed that the increase in production leads to an increase in profitability, and with the return of this profit in the carpet supply chain, it will lead to an increase in the quality of manufactured products. Also, in the analysis of the scenarios, it has been shown that by using a higher level of technology and new technologies, an increase in production can be achieved, and by implementing this scenario, in addition to increasing the quality of products and success in the market compared to the previous scenarios, with the delivery rate remaining constant, the costs Production will also decrease. Therefore, in the current situation, the best policy is to implement both scenarios at the same time.
