A SYSTEMIC APPROACH FOR SAWMILL MODELING

To illustrate how to perform sawmill modeling through the systemic app roach, an independent sawmill and a sawmill integrated to a pulp compl ex were selected and modeled. Applications of a methodology for modeli ng the operation, information. and decision subsystems are presented. Comprehensive diagrams assembling the different subsystems for both sa wmills are built. The fitness of this approach for the diagnosis of in tegration problems is shown. Examples of integration problems between production and administrative information systems, as well as organiza tional aspects of integration, are discussed. The systemic models appe ar to be useful tools to share a common vision of the organization and its mission.
