Uso de dinâmica de sistemas como suporte à decisão em propriedades produtoras de leite: um estudo de caso

The adequade management is the main factor of success in the milk production activity. In view of this, the objective of this paper was to develop a decision support tool based in system dynamics to be appled to this activity. To perform the simulations with the model they were used data from a representative milk production farm of the state of Minas Gerais, Brazil. The results obtained with simulations showed coherence with settled previously analysis. The system dynamics showed also to be very helpful to get a better understanding of milk production systems and to perform strategic planning.System dynamics, Milk production, Strategic planning, Farm Management,

Estrutura da tecnologia de produção agrícola regional: uma abordagem da programação de metas

The objective of this study was to analyze the average production functions and the frontiers production function to characterize the structure of the agricultural production technology. Using data of the agricultural census of 1995/96 regarding the mesorregião of the Triangulo Mineiro and Alto Paranaíba of the State of Minas Gerais the goal programming was used to calculate the parameters of the Cobb Douglas production functions. One of the main conclusions is the existence of significant differences in the level of productive efficiency and in the structure of the production technologies in this Mesorrregião, indicating the bias that is incurred when making decisions only based on the parameters of the average production function. Another important conclusion is the fact that the procedures adopted in this study, shows some evidence about the structural characteristics of the production technology offering better information for the decision makers
