Remanufacturing is an industrial process that makes used products reusable. Remanufacturing is a way to establish a closed-loop supply chain. One of the important aspects in both reverse logistics and remanufacturing is pricing of returned and remanufactured products (called cores) that it has been noticed in this paper. In addition, in this paper the researchers have tried to present a mathematical model that indicates prices and inventories in a closed-loop supply chain in an exclusive market. This model has argued on acquisition price of cores and remanufactured cores. Also, in the following the researchers essay discuss about acquisition price of cores in the competitive market via fuzzy rules. Numerical results demonstrate that appropriate values of the prices are obtained by these models
