Stochastic sum-of-ratios fractional programming model in an agricultural decision support system

The task of an agricultural management information system is to continuously provide the management with information required for decision-making within their scope of work. In order to do this, adequate quantitative models and computerized systems for their solving and analysis need to be implemented in the area of agricultural output planning. Since agricultural production is characterized by a level of uncertainty, it is normally not possible to estimate model parameters and relations with certainty, which has a direct impact on the effectiveness of planning. Such problems can be resolved to a significant degree by constructing decision support systems based on stochastic models. This paper will present as such the stochastic sum-of-ratios fractional programming model.
