Systemic Model of the Rice Chain. Plateau of Ibagué Case

Abstract

The rice supply chain in Colombia has low competitiveness, which happens mainly in the echelon of farmers. The problems are related to production costs, yield and paddy rice prices that impact farmers’ profitability. In this work, a dynamic simulation model is proposed, which combines elements of several authors. It follows the line that worked [1], it is incorporated the inventories of each of the echelons of the supply chain proposed by [2, 3] and the formulation of pricing described by [4]; to identify the actors and relevant variables of the chain, analyze the behavior of the rice chain in different situations and propose improvements. From analysis of scenarios, it was concluded that the cultivated area and yield are the variables that allow to achieve a greater impact on the profitability of the farmer.
