Inventory managers at blood transfusion centers are always looking to create sufficient reserves to increase access to various blood products and reduce losses due to the expiration date of blood. Because timely, appropriate and sufficient response of its suppliers to consumers is considered very important and necessary due to the corruption of blood, the uncertainty of blood demand and the direct relationship of its presence or absence with human life. This requires full knowledge of the demand of the covered hospitals as base users and decision-making on how to meet their needs in the best possible way in order to minimize the shortages and losses in the network. Due to the importance of this issue, in this article, we have tried to design and implement an optimal model of how to respond to the demand of hospitals in the Mashhad blood transfusion network with the aim of reducing the cost of waste and blood shortages. In other words, the proposed model determines when the blood transfusion centers receive orders from their consumers, considering how to respond optimally to the orders, given the available inventory, which results in the least losses and blood shortages. Have. In order to validate the proposed model, statistical parameters such as mean relative absolute error, mean absolute error, constant R^2and mean square error were used.
