Technological development of a forecasting model production for greenhouse tomato crop production, based on climatic, environmental and greenhouse variables of the area. Validation of the solution and creation of a software prototype as support tool to support for the construction of production agronomic forecasting model. Development of a support system for decision making (DSS) on the climate management, production and cost applied to a polygon greenhouses. It will be used as a simulator to assess climate, agronomically and economically different scenarios.
