Abstract
Neste trabalho foi discutido o impacto de perturbações estocásticas em um modelo de planejamento florestal. Foi desenvolvido um modelo de programação linear e uma abordagem, através de simulações estocásticas, para analisar e quantificar a variabilidade que ocorre nos valores da função objetivo, perante a natureza estocástica dos dados que alimentam o modelo. Um programa para efetuar tais simulações foi desenvolvido. O conceito de razão de variabilidade objeto-sistema foi introduzido para medir a suscetibilidade do sistema em relação às variações ocorridas no objeto.
The impact of stochastic perturbations in a forest planning model was discussed in this work. It was developed a linear programming and an approach, through stochastic simulations, to analyse and quantify the variability that occurs in the values of the objective function, because of the nature of the data that are used in the model. A program to do such simulations was developed. A new concept was introduced, called object-system ratio of variability, in order to measure the sensitivity of the response of the system when variations occur in the object.
