Abstract: The difference and relationship between the equipment-grouped in distributed numerical control(DNC) and dynamic unit re-organized in flexible manufacturing system (FMS) are analyzed. Derived from the production planning in FMS, a sort of new modeling and arithmetic about equipment-grouped in DNC system is discussed. This modeling and arithmetic is adapted to the integrated production management in automatization workshop based on DNC system.

Key words: DNC, Equipment-grouped, Integrated manufacturing, Production management
