An integrated data model for CIM planning and control

After describing a database-centered planning environment, the article concentrates on issues involved in developing an integrated data model. These include (1) the data requirements for representing modern manufacturing systems, (2) the data requirements for a decision-making environment, and (3) the data requirements of the planning models themselves. By emphasizing information relationships, the authors expect to establish an information structure that will combine computational models, database management, and, eventually, knowledge representation techniques developed in artificial intelligence research
