Aluminum recycling has many environmental and economic advantages and has attracted the most attention in different countries. Therefore, it is considered important to pay attention to the shape of the parameters in different processes, and to examine the various parameters of this industry, including the collection centers. collection, recycling process costs, market price and many other parameters are discussed and the degree of uncertainty in these parts is examined and analyzedTherefore, in order to investigate this issue of uncertainty in these sectors, various aspects of it have been investigated, which affect decisions related to investment in the field of metal recycling, which includes aluminum recycling. Therefore, in the current research, the main goal Optimal design of closed-loop reverse supply chain for aluminum recycling to maximize annual profit considering the uncertainty in the market price of aluminum collection, recycled materials and related logistics costs.. Therefore, the present research was carried out as a case study in aluminum recycling complex in Tehran province. The flow process of aluminum recycling in different facilities has been modeled based on the supply chain method, and the volume of the movement of recycled aluminum from consumer goods containing aluminum to the recycling center, from the recycling center to aluminum sheet production, from sheet making to ingot making and from ingot making which Finally, it reaches the retail sector, so that the profit from the whole process is maximized. For this purpose, limitations on the dimensions of the storage warehouse should be considered in the problem. Also, based on the defined goals and its limitations, the presented model suggests the construction of a new center in the field of recycling. Therefore, the results of the present study state; The construction of a new center for aluminum recycling will improve the level of production and increase the level of response to existing demands. which is determined based on the costs related to different sectors such as: transportation, maintenance and production and purchase, the amount of the available product and the shortages related to them. At the end of the research, a sensitivity analysis was performed on the outputs of the parameters of the proposed model
