Abstract: Abstract This paper presents a mathematical model of a potato supply and distribution chain in Latin America. We formulate a model for the distribution process from a set of potato producers to a set of nanostores (small retailers, common in Latin American countries) in both Bogotá, Colombia, and Cochabamba, Bolivia. In this model, we located a set of warehouses to consolidate and facilitate the distribution. The objective function was to minimize the sum of all costs subject to capacity, demand satisfaction, and coverage constraints. This model was implemented on the GAMS software; the results were translated into valuable information used to give shape to the distribution chain and to perform an analysis to further understand how the change in some of the input data could affect the optimal solution. The results show that even though the model implemented in both countries is the same, the results obtained are widely different because of each country's characteristics. This research opens the doors for future research that might consider traffic in the cities, criteria for the availability of producers, and even a vehicle routing solution for the delivery trucks. This model was developed jointly by students of Universidad de La Sabana and of Universidad Privada Boliviana as a part of a COIL (Collaborative Online International Learning) project.
