The rising and the characterization of production systems, in a conventional way, has it limited to the scale of the rural property, usually with analysis statistical univariate, just considering the size of the property and your main activity. With that, opted to develop a system computing for create types of units of family production through grouping analysis. Was used I Turbo Delphi, with the programming language Object Pascal. It was chosen the System of database Administration (SGDB) Relational Interbase 6.0. This SGDB presents the advantage of possessing open code, free license and, still, to be a light and fast SGDB. For the implementation of the system, opted to divide him in four main modules: a cadastral system, a tool of analysis univariate of data, a tool of grouping analysis and a georeferencing tool. To verify the operationalization of the application, the data of 34 rural establishments of the municipal district of Ivorá were used. Firstly, ocurred the analysis univariate of the data, being the tables and the analyzed fields, selected in agreement with the characteristics of the producers and your variability. Starting from the analysis univariate, the variables were selected for the construction of the head office that was used for the grouping analysis. A dendogram was generated where, it was verified that the rural properties formed four natural groups. The Group I formed by 15 properties, where the vegetables and fruits production associated with the tobacco prevails. The Group II formed by 16 properties, being characterized by automated traction, the soy appears as an important temporary cultivation and the production of swine raisin to have a very larger importance. The Group III formed by 3 properties, it is characterized by areas around 100 there is, the services rendered appears as an alternative of income. The production of vegetables appears as only productive activities. The Group IV formed by a property it is characterized by presenting an area of 153 there is, urban residence, soy production (60 ha), extensive creation of bovine of cut, honey production (120 beehives), and cheese (350 kg/year). The development of the tool computing for create types of units of family production, proposed in this work, he obtained success in your applicability. Showing like this, a better efficiency in the create types of units of production through techiniques multivariate.
