Systemography
Systemography or SGR is a process where phenomena regarded as complex are purposefully represented as a constructed model of a general system. It maybe used in three different roles: conceptualization, analysis, and simulation. The work of Jean-Louis Le Moigne is associated with systemography.
The systemography modeling consists of building, simultaneously, the process´ operational, the informational and the decisional systemographs in modeling phase. Ettore Bresciani Filho (2001) recommends the following order in the systemography modeling:
Define the border of the system to be modeled, characterizing the border´s processors responsible for the system´s inputs and outputs.
Build the operational systemograph of the production system, disposing in a block diagram the different stages of the production process, representing each one with an operational processor.
Build the informational systemograph of the production system, disposing in a block diagram the different stages of the information´s generation, transformation and communication, representing each one with an informational processor.
