Un modelo matemático para optimizar la cadena de producción de leche y queso en el sur de Nariño, Colombia

This study analyzes the milk production and processing chain in the southern region in Nariño, Colombia, through an optimization model aimed at improving the profitability of small-scale producers. Currently, about 44% of the region's milk is sent to collection centers and transported to large processing companies, resulting in frequent losses and reduced prices due to the product’s perishability. The proposed model evaluates the creation of processing plants managed by local associations under a solidarity economy approach, for transforming a part of surplus milk and increasing producer income. The optimization model suggests establishing a plant in Guachucal, one of the region’s top milk-producing municipalities, which could potentially double profits through the production of dairy derivatives such as cheese. Various scenarios were analyzed, supporting the feasibility of this strategy as a means to economically reactivate and strengthen the regional dairy sector.
