This article presents a networking model that allows to simulate the behavior of the of the principal productive agro-industrial chains belonging to the Department of Bolívar. The model was built by integrating in a single model the components of cost, production and utility of each of the actors in the different chains; the model of networks elaborated with the help of the software I Think. On having defined the principal variables that characterize the model raised different scenarios to determine the sensitivity of the same and as these changes affect productivity, employment, and the utility of the actors.
