Systemography (SGR[1]) is a process where phenomena regarded as complex are purposefully represented as a constructed model of a general system.
Ettore Bresciani Filho (2001) recommends the following order in systemography modeling: To systemograph consists, in a few words, in building a model, physical or mathematical, static or dynamic, analytical or numeric of a phenomenon that can be noticed as complex by the analyzer that intends to model it.
These systemographs allow to observe and to eliminate redundancies and cycles that are (or not) important for the process, providing its systemic visualization, identifying points to allow its rationalization, increase of flexibility, and activation.
The systemography was studied and presented theoretically by Jean-Louis LeMoigne (1990; 1994) in his Théorie du Système Général (1994).
Bresciani Filho presents, in his works and through his students, a practical use of the systemography concepts, particularly for systems of production and of information.
