摘要：The purpose of this paper is to present the causal loop diagram method.For that purpose, a qualitative modeling of the system was accomplished through the Feedback Cycles Diagrams, making it possible to understand that citrus agriculturists make decisions on planting based on incorrect and sometimes twisted information. That is due, mainly to the production lead time, which spreads for four years Keywords: agribusiness model, causal loop diagram, system dynamics
