The paper considers the OSH management system in the enterprise with all internal connections and input - output parameters. The method IDEF0 model is built in a hierarchical pyramid in the top of which a general description of the system and at the bottom - the set of more detailed descriptions. It has been described in the methodology IDEF0 model system using IDEF0 graphic diagram. Wherein it’s model includes a series of interconnected " Diagrams", which divide a complex system into its component parts. "Diagram" higher layer (A0) is the general description of the system shown in separate blocks. Decomposition of this "Blocks" allows you to achieve the required level of detail in the description of the system.
