Sustainable supply chain management (SSCM) systematically coordinates internal organizational processes to achieve economic, environmental and social goals and increases the long-term economic performance of companies and supply chains. In this study, the importance of paying attention to the sustainable supply chain, which includes financial, environmental and social responsibilities, has been discussed as an important principle in today's competitive world, and at the same time, the control of inventory fluctuations that leads to the reduction bullwhip effect in the supply chain is also discussed. On the other hand, while most of the articles have used the reduction of costs or the increase of income or profit as a financial approach, in this research, the use of comparing the economic value of the supply chain activity with the interest rate, which can be a more comprehensive approach, has been considered. The model presented in this thesis was first solved by the augmented epsilon constraint method in GAMS software, and then considering the complexity of the problem which is included in the category of np-hard problems, a multi-objective genetic algorithm was presented to solve the examples in large dimensions and the convergence of the solutions using MID and SNS indicators have been eva‎luated. At the end, the investigation and analysis of the control performance of the bullwhip effect on the chain shows that by applying control over the fluctuations of the inventory (control of the bullwhip effect), the economic function of the model (NPV) is improved by 40% compared to the case where the control of the bullwhip effect and demand fluctuations is not applied.
