Agri-food supply chains (ASC) focus on stakeholders with the objective of providing access to essential inputs, processing primary products, marketing and distributing the products to end consumers. In this context, it is proposed to design a model for locating rural centers that serves as logistical support for the yam agri-food supply chain. This location model for hubs aims to plan the distribution in the agri-food supply chain of yams in the Sabanas Subregion of the Department of Sucre, Colombia. Additionally, the use of the Hub Location Problem is considered, which is addressed as a mixed integer linear programming model. To this end, assumptions have been adopted that will allow obtaining results that maximize the profits of the warehouses (hubs). These results have been obtained through the use of GAMS software, solved with the CPLEX Solver. According to the results obtained, the optimal location for the opening of two strategic hubs has been identified. These distribution centers not only help reduce logistics costs, but also optimize delivery times, thus strengthening the supply chain.
