A production management information model ' for discrete manufacturing

The Manufacturing Systems Integration (MSI) project at the National Institute o f Standards and Technology i s developing a system architecture that incorporates an integrated production planning and control environment. T h e development of this architecture includes the definition of information models describing the information which needs to b e shared among production management systems (production planning, scheduling and control systems) in order to achieve the integration o f manufacturing systems. This paper presents the production management information model within the MSI project. The main focus of the model i s to identify and characterize the relationships between orders and workpieces, to identify the information necessary to achieve workpiece tracking and to identify the information necessary to achieve resource requirements specifications for process plans.
